SamSa Ransomware – Blog Week 12

For the final week, the suggestion topic was kind of the same as the topic for the Final Reflection for the course so I decided to write something different.  The topic for week 12 that I would like to write is about the SamSa Ransomware.

The SamSa Ransomware was also known as MSIL/Samas.A.  SamSa Ransomware happened in the middle of the year 2016.  It hit different businesses, such as healthcare, industrial control, and government.  SamSa Ransomware had exploited the vulnerabilities of the Remote Desktop Protocol (RDP) connection and JBoss systems to carry out its infections.  The majority of the victims are in the United States and some internationally.
This is how the SamSa Ransomware worked.  It exploited Windows servers to gain persistent access to a victim’s network and infect all reachable hosts by using the JexBoss Exploit Kit to access vulnerable JBoss applications and RDP to gain access to victims’ networks.  The main method that the hackers used was the brute force attacks or stolen login credentials, which “cyber actors purchased several of the stolen RDP credentials from known darknet marketplaces” (US-CERT, 2018).  After having access to the network, the hackers escalated privileges for administrator rights, dropped malware onto the server, and ran an executable file.  The actions were performed without victims’ notice or authorization.  SamSa Ransomware was very dangerous ransomware.  It is because it did not relied on any victim completing the action, such as opening an email, clicking on a link, or visiting a compromised website.

SamSa Ransomware targets are big organizations.  The “Network-wide infections against organizations are far more likely to garner large ransom payments than infections of individual systems. Organizations that provide essential functions have a critical need to resume operations quickly and are more likely to pay larger ransoms”(US-CERT, 2018).  SamSa Ransomware often leaves ransom notes on infected computers.  If a victim wants to gain the control back on the computers/servers, they have to follow the instruction, which directs the victims to establish contact through a hidden service site to pay the ransom.  The hackers want to have the ransom in Bitcoin.  After the victim pays the ransom, the hacker sends a link for the victim to download cryptographic keys and tools to decrypt their computers/servers.

To me, the ransomware is the warfare between the White Hat hackers and the Black Hat hackers.  The Black Hat hackers often are criminals performing illegal activities for personal gain and attacking others.  They often violate computers/servers/network security for personal benefit, such as stealing credit card numbers, social security numbers, bank accounts, or harvesting personal data for sale.   On the other hand, White Hat hackers are the opposite of the Black Hat hackers and they are often known as “ethical hackers”.  They are the ones that have the roles to play against the Black Hat hackers and finding security holes via hacking methods like the Black Hat hackers, performing penetration testing, testing in-place security systems and performing vulnerability assessments for companies with permission from the companies.

The warfare between the Black Hat hackers and White Hat hackers would never end.  It’s because both Black Hat hackers and White Hat hackers are living by hacking.  One main difference between them is one is doing the hacking with good purpose and the other one with bad purpose.  I always have questions for the Black Hat hackers.  Black Hat hackers have good computer skills and I am sure that their skill can qualify for many security positions for any organizations.  Why do the Black Hat hackers not choose the legal ways and jobs, but go with the illegal ways?  Why can’t they become a White Hat team while they are doing pretty much the same task as the White Hat team?

I read the article “Black-hat hackers more daring and experienced than white-hat hackers” that was written by Steve Morgan. The article shocked me by indicating “Sixty-five percent of respondents to a poll say black hats are more experienced than white hats” (Morgan, 2017).  If this is the true case, then there will be more viruses, ransomware, cyber-attacks, and more security breaches happening in the future.  Perhaps, the only way to help reduce those security issues is to have a strong White Hat team, which has more experience than the Black Hat group.  The White Hat team must be smart and at least one step ahead of Black Hat hackers to predict and know the methods of hacking from the Black Hat so that they can prevent it.  It’s just a hypothesis and I would never think the world could stop the Black Hat hackers.  It’s the nature of law.  There are always two things that go against each other.  They are good and bad, negative and positive, hot and cold, etc.

Action Plan – Week 10

In the week 9 and week 10 assignments, I had a chance to learn and work on the Action Plan.  It was a step further after the Threat Analysis that was completed from the week 7 and 8 assignments.  Without the Action Plan, I think the Threat Analysis was an incomplete document for the company to mitigate the risks.  The Action Plan is an add-on task to the Threat Analysis to make the whole document complete.

When working on the Action Plan, the most difficult part was how the format of the Action Plan looks.  What needed to be included in the Action Plan?  I had to do some research and through the study, it helped me to have a much better understanding of the Action Plan.   The Action Plan is a “sequence of steps that must be taken or activities that must be performed well, for a strategy to succeed. An action plan has three major elements (1) Specific tasks: what will be done and by whom. (2) Time horizon: when will it be done. (3) Resource allocation: what specific funds are available for specific activities” (BusinessDictionary, 2019). 

To be more detailed, a good Action Plan consists of many steps, but each step should include the following information:
1.      Actions
2.      Responsible groups
3.      Timeline
4.      Resources, such as money and staff for making the changes
5.      Communication

The good Action Plan should include three main elements above, which are listing out specific tasks, timelines, and resource allocation.  The specific tasks for the case study of the class were to be able to identify all the assets, then recognize the threats, vulnerabilities, and risks associated with each asset.  In addition, one of the most important tasks is to provide recommendations to fix the security issues with detail actions.  Without recommendations and detail actions, the company would not know how to fix their security problems.  Providing the timeline for each task is also an important factor within the Action Plan.  The timeline will show when the task should be started and when the task should be done.  This will help both management and technical groups to know when to start the tasks and when the tasks should be completed.  It especially helps the management group to allocate the time, budgets, and resources.  The last important element of the Action Plan is resource allocation.  In this step, it helps management groups to be able to plan for the funds and assign the task to the right groups or person to work on each task. 

When we have a good Action Plan, it will help the organization improve security greatly.  It is because the Action Plan lists out the assets for the company.  It evaluates the threat and vulnerability of the assets.  It then analyzes the risks and potential impact on the company.  After that, it provides recommendations and solutions to fix the security issue.  “An action plan is a way to make sure your organization's vision is made concrete.  It describes the way your group will use its strategies to meet its objectives” (CommunityToolBox, 2019). 

So how we can make a good Action Plan?  There are three criteria that help us to make a good Action Plan.  They are: complete, clear, and current (CommunityToolBox, 2019).  For the completeness, it indicates that all the action steps to be sought in all relevant parts of the community.  For clearness, it indicates if the Action Plan is clear, easy to understand, and clearly indicates the who, what, and when to perform the task.  For the current point, it indicates if the action plan reflects the current work.

The assignments for the last four weeks were very practical and I valued them a lot.  They are all new concepts and ideas to me so I love to learn them and I am sure they will benefit me for my future work.  I have learned much from the classes for the Cybersecurity program and I could tell that the Current Trend in CyberSecurity class is one of the most practical classes that I have had.  It is good information and very practical.

Apple FaceTime Vulnerability – Week 9



The last couple of days, the tv and newspaper talked about the Apple FaceTime Vulnerability.  It was one of the security holes that Apple has on their products, such as iPhone, iPads, and Mac computers.  A vulnerability happened in Apple FaceTime application.  It allows someone to access audio and video on another Apple device even when the recipient does not answer the call. This vulnerability applies to Apple iOS users who have Group FaceTime capability on iOS 12.1 or later.

This was how the vulnerability actually happens:

When user #1 starts a FaceTime call with user #2, while the call is processing, the user #1 adds a person and then enters their own phone number.  The user #1 can then hear the audio from the user #2, even when user #2 hasn’t answered.  “The problem was the result of a bug and involves Apple’s FaceTime app for placing video and audio calls over an internet connection. The bug could also give caller access to a live feed of the recipient’s camera” (Chen, 2018).

For now, Apple has disabled the Group FaceTime feature and has tried to fix the bug.  I hope that Apple could fix the bug as soon as possible and resume the Group FaceTime feature for the users.  I am not a big fan of Apple, but I am a big of Android.  I have a small business and I use Messenger for group chat.  Messenger has similar features as Group FaceTime and I love to use this feature to have a meeting with my employees when I am away from the office.

I came from a software development background and when I heard about this security bug, I could tell that Apple needs to update their software development life cycle (SDLC) as soon as possible.  Their SDLC has a serious bug.  It’s either their employees not performing the tasks correctly within the SDLC or the SDLC missed important steps to verify the quality and security of the software.   As a big and well-known company like Apple, they should not have this kind of bug that leads to a huge vulnerability to the customers.  Here is what I could tell Apple needs to do with the SDLC.
First, they need to create a design (general design and detail design) with a flow diagram for the Group FaceTime feature.  With a flow diagram, it should give senior developers, security software developers, and architect software engineers the ability to review the whole process and catch any security issue.

Second, when the developers write the code, they would be able to understand the whole process before coding.  They should be able to catch the security issue when coding and especially testing.  The testing from the developer is considered a unit test, but it could catch great defective errors.
Last, Apple Quality Control (QA) team did a bad job.  Their testing scripts, testing different cases, and different groups of users were not throughout.  QA plays a very important role.  They need to work with senior developers to come up with different test cases and make sure the product is free from error in terms of logical errors and security errors.

Depending on the products, each company will have a different rating level for the defective acceptance.  For example, if a system (software and hardware) is written for a hospital to distribute medicine to the patient, the required defective acceptance level would be - 0.00001% or +0.00001%.  It is because if the system distributes 1mg less or more of medicine this could cause a serious problem to the patients.  If a system (software and hardware) is written for distributing food for the pets, the required defective acceptancy level could be -10% or +10%.  In this case, the defective level could be large and it is still acceptable because it won’t hurt the pets when the system distributes a bit more or less food for the pet. 

Back to the Apple FaceTime system.  It’s a security issue and the product serves the whole world.  Therefore, it is critical for Apple to not have this security problem.  The issue did not only hurt the customers, but it also hurt Apple itself financially (the stock market went down) and Apple’s reputation.

Dharma Ransomware Attack - Week 8


A ransomware attack is one of the most critical security breaches.  Here is some general information about the ransomware. 

  • ·        It infects computers through clicking an unsafe link or downloading unsafe programs. These can come in e-mails, torrents, botnets, or other forms of transmission.
  •       Ransomware can’t be removed even when the computer’s owner flashes the BIOS, wipes the drive, or attempts to return to a prior restore point.
  • ·        A ransomware often locks down user files and the ransom demand is made, while a unique decryption key is created and stored on the hacker’s servers. “If the ransom is not paid in time, or if any attempt to alter the program directly is made, the decryption key is permanently deleted, rendering all encrypted files inaccessible. If the ransom is paid in time, the decryption key is transferred and the files will be decrypted” (Alvarez, 2019).


On December 2018, a Phobos ransomware exploited open or poorly secured remote desktop protocol (RDP) ports.  It snuck inside the networks, encrypted files, and demanded a ransom be paid in bitcoin for returning the files.  The ransomware was created by Dubbed Phobos, which people believe this group also the creators of the Dharma ransomware.  “Phobos also contains elements of CrySiS ransomware — also related to Dharma — with anti-virus software detecting Phobos as CrySiS. The ransomware's file markers also differentiate it from Dharma. However, the attack methods and threat remain the same” (Palmer, 2019).  With so many similar ways of an attack, the researchers believed that Phobos ransomware was just the modification of Dharma ransomware. 

The Dharma ransomware attack happened on September 3, 2018, which was about 3 months before the Phobos ransomware.  Dharma ransomware hit the Altus Baytown Hospital (ABH).  It snuck into the ABH network with malicious code and infected the hospital's systems.  The Dharma ransomware was able to encrypt files and then demanded a ransom payment in return for access.  The files “included files containing patient information such as names, home addresses, dates of birth, social security numbers, driver license numbers, credit card information, phone numbers, and medical data” (Osborne, 2018).

The world will continue to deal with more data breaches and cyber attacks.  Therefore, it is the businesses’ responsibility to prepare and prevent themselves from all the possible security issues.  Now, it would cost business quite a bit of money and effort to build and maintain a strong security network.  If companies don’t have enough funds for security, they can go with the following options:

1.    Cloud solution: There are the services that provide the computing resources for business.  It includes everything, such as from application to the data center and obviously, the security network with the cloud is designed and secured by the best security experts.  The service is mainly through the internet on a pay for use basis. 

2.    Pay-as-you-go model: “One major benefit of the pay-as-you-go method is that there are no wasted resources, since users only pay for services procured, rather than provisioning for a certain amount of resources that may or may not be used. With traditional enterprise design, users architect data storage to handle the maximum workload. But with the public cloud, the pay-as-you-go method allows you to be charged only for what you store” (Rouse, 2015)

Recap for the first half of the Class - Week 7


For the last six weeks, I have had a chance to learned real practical lessons from the cybersecurity.  The first two weeks, I learned how to create the Threat Model Process.  Then the next two weeks, I have learned how to use the Threat Modeling tool.  The last two weeks, I have learned how to perform the system analysis for a case study. 

For the Threat Model Process, I have no experiences on this.  Working on creating the Threat Model Process, I had a chance to study, do research, read other classmates’ work, and getting back the valuable feedback from the professors and classmates give me a good understanding about the Threat Model Process.  Each enterprise would have a different type of businesses and each business required different security controls.  I believe that if the company could come up with their own Threat Model Process, which could review by the experienced security experts, then the company can just use the Threat Model Process to verify all the threats, vulnerabilities, and risks within the organization and monitor then mitigate them.  Having a good Threat Model Process and seriously practice on it, companies would be able to have a low number of security issues.

For the Threat Modeling Tool, which is the tool that is used to perform a systematic analysis of attack vectors.  Through the homework and exercise for the class, I would be able to search, know, and learn many different Threat Modeling Tool, such as:

•    SecuriCad by Forseeti – It is the “is a threat modeling and risk management tool that enables you, the user, to get a holistic understanding of your IT infrastructure, incorporating risks from both structural and technical vulnerabilities” (Kumar, 2013)
•    ThreatModeler – It is the tool that helps to “Identify, predict and define threats across the entire attack surface to make proactive security decisions and minimize overall risk” (Threat Modeler, 2019)
•    Irius Risk – “this tool helps create a threat model and derive security requirements in no time using a straightforward questionnaire based system” (Kumar, 2013).
•    SD Elements by Security Compass – It is “An Advanced Automation Platform that Builds Security, Compliance, and Policy into Applications” (SecurityCompass, 2019)
•    Microsoft Threat Modeling Tool 2016 - is a free tool that was designed by Microsoft.  It is one of the best tools that can help any organization to create the threat modeling process.

For the system analysis, I have not had any experiences in performing any system analysis before.  I came from a software development background and I have done a lot of design documents for various projects.  However, system analysis is something that is a new concept for me.  Though the assignment for the last two weeks, I had a chance to perform the system analysis for a case study.  It was a good learning lesson.  Along with reading the assignment, reviewing other classmates’ work, and especially the feedback from the professor, I have a good understanding of how to perform a system analysis.  For example, when performing a system analysis for a company, I should identify all the current assets, processes, and policies within the current IT environment.  Explain their function and their effects if something bad happens to them.  A system analysis should be succinctly and all the complicated technical terms must be translated to the common business terms for the readers, mostly executives to understand. 

So far, I really enjoy this class.  It gives me a deeper knowledge and practical exercise for threats/vulnerabilities analysis.  I am looking forward to the other half of this class to continue to learn more about security and different aspects of the cybersecurity field.

Aadhaar - Biggest Data Breach in 2018 - Week 6


Data breach is one of the security threats that will continue to grow in the future.  Hackers are trying to make money from the data that they steal.  This threat does not only hurt the businesses, but it also hurts the customers or the citizens.  Following was the biggest data breach that happened last year, which was 2018.

Aadhaar data breach happened in India.  It hit the Indian database that keeps identifying and biometric information of more than 1.1 billion registered Indian citizens (Whittaker, 2018).  The citizens who registered with the Indian government with their fingerprints and biometric data will have the benefit of opening the banks, buying a phone SIM card, enrolling utilities, using government basic services, and receiving state aid or financial assistance. 

According to ZDNet, hackers had “access to the Aadhaar database through an API, which the company relies on to check a customer's status and verify their identity” (Whittaker, 2018).  The API (Application Programming Interface) was not secure and had no access controls in place, which left a security hole that allow hackers to retrieve private data on each Aadhaar holder.  “The affected endpoint used a hardcoded access token, which, when decoded, translates to ‘INDAADHAARSECURESTATUS,’ allowing anyone to query Aadhaar numbers against the database without any additional authentication” (Whittaker, 2018). 

Another security issue with the API was “the API didn't have any rate limiting in place, allowing an attacker to cycle through every permutation -- potentially trillions -- of Aadhaar numbers and obtain information each time a successful result is hit” (Whittaker, 2018).  This security hole allowed the attacker to send thousands of requests to the database each minute and get the information.  Therefore, this caused a huge number of data breaches, which impacted 1.1 billion people.

Not only hackers, but anyone with some knowledge and experience with the API can access the government’s database.  “The Tribune newspaper said its reporters were able to access names, email addresses, phone numbers, and postal codes by typing in 12-digit unique identification numbers of people in the government's database, after paying an individual about $8. For another $5, the newspaper said, the individual offered reporters software to print out unique identification cards, called Aadhaar cards, that can be used to access various government services including fuel subsidies and free school meals” (Doshi, 2018).

Regarding a data breach, each country and business might react and solve the problem differently.  I could tell that in the US, the government, businesses, and private sectors respond to the data breach very quickly and effectively.  In India, “the Indian authorities did nothing for weeks to fix the flaw” (Whittaker, 2018).  Why did the Indian government and authorities respond so slowly on the Aadhaar data breach?  Do you think it’s because the data breach happened to the public property, not a private sector? 

When it comes to the property of public or private, I often see people use it differently.  For public property, people often use it improperly, carelessly, and waste a lot.  For example, I have seen people who work for government office printed thousands of pages for a project when the document was not finally done yet.  A person later reprinted the document when it got fixed.  Now, I am working for a small private company.  My manager, the owner of the company, even suggested that I do not print any document if it can be shared through email.  Not only printing but any office equipment or office supplies the company uses them wisely. 

Back to the Aadhaar data breach, I think this security breach happened because the properties belong to the public.  People often don’t pay special attention to public property.  The way people handle and maintain public properties are often with less attention.  Aadhaar data breach was one of the clear examples.  “ZDNet spent more than a month trying to contact the Indian authorities -- including the Indian government's National Informatics Centre. Nobody responded to our repeated emails” (Whittaker, 2018). 

Here I have a couple of questions that I would like to ask the readers.  Do you have friends or relatives who are currently working for the City or State office in the US?  Do you think they have a lot of work to do?  Do you think they spend their time wisely at work?  Do you think they use public property correctly?

Spoofing Threat - Week 5

From the readings and lessons of the last couple weeks, I had a chance to learn about the STRIDE model.  This model was developed by Microsoft in order to help security engineers understand and classify all possible threats.  Each letter of STRIDE represents one type of threat as follow:

S stands for Spoofing, which is an act of pretending to be something or someone you're not.

T stand for Tampering, which is an act of modifying something you're not supposed to modify.

R stands for Repudiation, which is an act of claiming you didn't do something.

I stands for Information Disclosure. It is the exposure information to people who are not authorized to see it.

D stands for Denial of Service.  It is one type of attack that prevents valid users from accessing the system due to the system being flooded and running into a very low or critical resource that can't validate valid or invalid users anymore.

E stands for Escalation of privilege.  It is a threat related to either a program or any operation within the company doing things that they are not supposed to do.

In this particular post, I am going to talk about the first threat, which is the Spoofing threat.  As I have mentioned above, Spoofing is the threat of someone pretending to be something or someone they are not.  Most security systems rely on the identification and authentication of users.  How can the security system could tell if a user is a valid user?  For example, when student A using the login credentials of student B to log into the class website, the security system would not be able to identify the valid user in this case.  I would say the security system would fail.

We are living in the age of technology now, and this helps many businesses be able to expand their businesses, services, and increase the number of customers so quickly and successfully.  For example, we see so many companies taking advantage of technology to shop online.   Amazon is one of the most successful examples.  Almost every other big brands have also expanded their business and services through online service as well, such as BestBuy, Walmart, Target, Sears, and many universities too.  Twenty years ago, online classes might not have been available but now, it is common and helps both students and professors to learn and teach at their most convenient time.  Now, here is a different type of Spoofing threat that I would like to bring up and challenge all the universities, including Bellevue University.

How are you going to know if the student who is taking an online class is really the one who does all the assignments, quizzes, and exams?  For example, a student can "hire" someone to do all the work for them, this includes the weekly posting, assignments, and tests.  When hiring someone to do the work for them, the students give their login credentials to the person who they hire to do their work to login into the class website and perform all the work.   In this case, how are the school, the security system, and the professors able to identify if the user is valid and authorized to log into the website and perform the work?    

I brought this concern up and ask you, as a reader a question.  Do think this is a Spoofing threat?  If you think it is a Spoofing threat, then what do you think the best ways to defend against for this threat?  When I was thinking about this threat, I had two different thoughts.  First, an online class might not reflect the best quality and value of the students.  Second, the online program has some security holes.  With that, how do you think to fix these security issues? 

Here is just one way to fix this security threat that I could think of.  Each week, a professor can schedule a 30 minutes online meeting face to face with students through webcam to review/test the student.  I personally like the SYNC & Telephone meeting option that the Writing Center has.  This option allows students and the Writing Center staffs talk face to face about the papers.  Bellevue University should also have this option available for professors and students to meet online face to face and review the material.  The professors can use SYNC & Telephone meeting option to test students on the lessons that he/she teaches the students.  When doing the exams, students also need to log into the SYNC & Telephone meeting to do the test with verification from the professor or any staffs from the school.

Above is one specific Spoofing threat, which might be very different from the Spoofing threats of information technology. Do you think it is a Spoofing threat? It could be one threat that I am not sure if the school and professors ever thought about.  I hope this threat never happens, but if it happens, how the school could handle this threat?

Top 10 Threats to Information Security - Week 4

Top 10 Threats to Information Security

Last week, I was talking about the data breach case that happened to Marriott hotel.  Data breach is one of the most critical threats to all organizations.  This threat will never stop, so all businesses and homes need to be well prepared for defending against this threat.  This week, I am going to expand on the security risk and talk about the top 10 threats to information security. 

According to Georgetown University, the top 10 threats to information security are:

1. Technology with Weak Security - This threat comes from new technology and new technology devices, especially devices with Internet access that have little or insecure security protection.  With the fast development of technology, some innovators focus more on new inventions or features for technology, but focus less focus on security, which causes security holes in the development of technology.

2. Social Media Attacks - Social media has boomed in the last decade or so.  According to the latest social media statistics, "81% of the U.S. population has a social media account. That amounts to about 264 million people” (Lincoln, 2018).  With a huge number of people using social media, Cybercriminals have exploited social media for attacks, such as the Water Holding attack, which is when attackers identify and infect a cluster of websites they believe members of the targeted organization will visit.

3. Mobile Malware - According to Statista, "In 2019 the number of mobile phone users is forecast to reach 4.68 billion. The number of mobile phone users in the world is expected to pass the five billion mark by 2019" (Statista,2018).  With more and more people using mobile devices, I believe that there will be more mobile threats, malware attacks, and more threats/vulnerabilities on mobile devices.

4. Third-party Entry - Many enterprises use third-party software/services for their business.  The reasons being are the third-party service providers are often highly experienced, certified, and efficient.  Another reason is to save money for the company.  For example, if the company wants to write their own antivirus software, it would cost a lot more money than just buying one from the third party.  However, third party software or services have security holes too, and Cybercriminals could exploit those security holes to steal confidential data.  For example, "HVAC vendor was the unfortunate contractor whose credentials were stolen and used to steal financial data sets for 70 million customers" (Georgetown University, 2018).

5. Neglecting Proper Configuration - most security controls come with default settings and the settings do not fit all businesses.  It is not "one size fits all", so when the enterprises use security controls, they need to understand the tools and configure them to best fit with the business needs.  Do not use the default security settings. 

6. Outdated Security Software - a common mistake about this threat is when a business uses antivirus software but does not configure it to auto update the definition files.  Both businesses and homes are facing new threats every day.  Without having the latest security software or definition files, both businesses and homes are vulnerable to the current threats. 

7. Social Engineering - this threat is so popular now that hackers try to use different techniques on social interaction and psychological manipulation to gain access to confidential data.  The common techniques that hackers often use are phishing, spear phishing/whaling, pretexting, water hole, and tailgating.

8. Lack of Encryption - To protect data at rest or in transit, companies should protect the data by encrypting the data.  For example, all websites, especially the websites with the online transactions, should use https.  For sensitive data at rest, they should be encrypted.  For example, SSN, date of birth, addresses, banking account numbers, and driving license numbers should all be encrypted.

9. This is another common threat since many enterprises have started using the Bring Your Own Device (BYOD) option.  For example, many employees use their personal phones to connect with their worked email server to read emails and download work documents to the phone for review.  The same thing for laptops; many employees use their own laptop for work.  One common security problem is the personal devices don’t have any type of encryption, and if the device get stolen, people can retrieve and view the information easily.

10.  Inadequate Security Technology – companies need to invest the right amount of money for security technology.  Security is a trade-off between risk and cost.  Each company has different types of business.  Spending more or less on IT Security is dependent on each company’s situation.  However, “businesses now spend a higher percentage of their IT budgets on security than ever before. According to the survey, large organizations spend an average of 11 percent of their IT budgets on security while small businesses spend nearly 15 percent” (Rubens, 2015)

These are the things that you need to consider for today security.  Wherever you are at work or at home, those threats can happen to you.  It is good to know the current threats so that you can understand and defend against them.  I always like a sentence: “Prevention is better than a cure”.  Do you agree with me on this?

Marriott Data Breach

We are living in the age of technology and at the same time, we are facing a variety of threats within the IT or cyberspace environment.  For example, many of us are carrying credit cards or debit cards now instead of carrying cash to make payment for the purchases.  According to The Nest, “The Census Bureau estimates 183 million Americans have credit cards. Of those Americans, 104 million have Visa cards, 83 million have MasterCard, 99 million have a store card, 56 million have an oil company card, and 36 million have an American Express card. There are 1.27 billion cards in use” (Skeen, 2018).  For debit cards, according to the MarketWatch, “Americans use debit cards twice as much as credit cards” (Lamagna, 2016).  Why are more and more people using credit cards or debit cards nowadays?  I think it is because it is more convenient and more secure.  For example, when traveling and booking for a hotel, it is much easier to use cards to book a hotel room or restaurant reservations.  Now in most of the cases, the hotel requires their customers to provide the credit card or debit card information, and the person's name, addresses, phone number for the reservation.  This request has become a norm or common procedure for the hotel to book a room for the guests.  If the hotels have good methods to collect and keep the customers’ information safely, this would help their guests to protect their sensitive information.  If the hotels don’t have good methods to collect and keep the customers’ information safely, both the hotels and their customers would run into a serious security problem. 

Two weeks ago, there was shocking news about the data breach.  The news broke that Marriott’s Starwood guest reservation database encountered a data security incident.  The data breach impacted hundreds of millions of guests who made reservations at a Starwood property that runs a number of hotels, including the St. Regis and Westin chains.  The information at risk includes name, phone number, mailing address, email addresses, passport numbers, birth dates, arrival/departure dates and information, and potentially credit card numbers of the customers.  This data breach was considered “the second largest data security breach in history” (2018, U.S. Gov Connect).  It was just after two record-setting Yahoo hacks. 

Since the data breach was focusing on the information of the large percentage of the world’s travelers “that Marriott may have been the target of nation-state hackers seeking to track the movements of diplomats, spies, military officials and business executives” (Timberg, Telford, 2018).  In recent years, when there are many conflicts among the US, China, Soviet Union, North Korea, and Iran and when something like this happens, it always makes me think the hackers must come from those.  For this particular data breach, it was assumed that “Chinese intelligence could have been involved in the data breach that affected 500 million guests who have made reservations with hotels under Marriott's Starwood division” (Chong, 2018). 

Private investigators believe China was the culprit of the Marriott data breach because the similar tools, techniques, and procedures have been used in earlier cyberattacks that have been linked to Chinese hackers.  In the coming years, I would say these countries, especially China, would cause more data breaches, more cyberattacks and the targets are mainly companies, government offices, and households in the US.  It’s because President Trump has imposed “tariffs on $200 billion worth of goods and was prepared to tax all imports” (Bradsher, Tankersley, 2018) from China.  The acts that President Trump has done really make China angry and they wants different ways to retaliate againts President Trump and the US. 

China often tried to steal intellectual information from the US.  As you can see, within the last four decades, they can build their own their aircraft carrier.   They can build the J-10 fighter that has many same features and functions as the F-22 or F-35 steal fighters of the US.  The US has invested millions of dollars and efforts to build those fighters and it took years to build those aircraft.  How is it possible China can build the aircraft carrier and the most advanced J-10 fighters in a short time?  Do you think they built them by their own knowledge?  I would not think so.  The tension between the US and China will continue to increase based on the economy and military since China wants to dominate the world and the US does not want that to happen. Therefore, more data breaches and cyberattacks will happen.

Credible sources of information for threats, vulnerabilities, updates, and security news

We are living in the age of technology and we are inheriting many results from high technologies that help various aspects of our lives.  For example, in communication, we can talk and see the face of people who live halfway around the earth.  We can send a message that can reach everywhere on the globe by just one click.  For education, we can take online classes now that fit perfectly the time and schedule for the students who are working full-time.  For e-commerce, it saves us time when we shop online.  Amazon is one of the best examples for the most successful e-commerce.  Technology is good, but many people take advantage of it and use it unlawfully.  That’s why we face different security threats every day.  Following are credible sources of information for threats, vulnerabilities, updates, and security news that organizations and home owners can use for their protection and prevention.

1.      SANS (SysAdmin, Audit, Network, Security) - https://www.sans.org/ 
SANS is not only providing computer security training and certification, but it is also providing the most current information for threats, vulnerabilities, updates, and security.  Under the Resource menu, it provides newsletters, blogs, critical security controls, and critical vulnerabilities.
2.      MIT Technology Review - https://www.technologyreview.com/ 
MIT Technology Review provides different journals, analyses, reviews, essays, and reports about the current important new technologies.  It also provides cyber threats and vulnerabilities for both businesses and non-businesses to be aware of.  For example, on Jan 2, 2018, MIT Technology Review had an article “Six Cyber Threats to Really Worry About in 2018” written by Martin Giles.  He mentioned six critical cyber threats for the current year, which were data breach, ransomware in the cloud, the weaponization of AI, cyber-physical attacks, mining cryptocurrencies, and hacking elections.
3.      Symantec Security Center - https://www.symantec.com/security-center 
The Threatpost of Symantec Security Center is a publication that provides daily articles, podcasts, and videos on all security. It provides reports on a new vulnerability or threat that may be affecting organizations at large.  The publication is a great daily resource for both organizations and people to learn and understand the current security threats and vulnerabilities.
4.      Kaspersky Lab – https://threatpost.com/
Kaspersky Labs’ Threatpost is a publication that provides daily articles, podcasts, and videos on all things security.  It focuses on the most current threats and attacks.  It is one of the trusted and useful sources for all organizations and employees to read and be aware of the threats and not be exposed to them.
5.      McAfee
McAfee is one of the most well-known antivirus software.  Besides the best antivirus software that McAfee provides, it also provides the current security reports, security trainings, security awareness, security controls, and all the current threats and vulnerabilities.  Under the Threat Awareness main menu, there is a Resources submenu that provides so many articles about current threats, vulnerabilities, ransomware, and threat reports that are beneficial for both businesses and home.
6.      The National Cybersecurity and Communications Integration Center (NCCIC) - https://www.us-cert.gov
The NCCIC is the Nation’s flagship cyber defense, incident response, and operational integration center.  It provides the most current cybersecurity threats that all businesses or homes could be aware of.  For example, on its homepage, it lists the current security breach of Marriott International Starwood guest reservation database.  Another critical security that NCCIC mentioned was the SamSam Ransomware.  Its targets were multiple industries, including some within critical infrastructure in the US.  The main attacks of SamSam were gaining access to victims’ networks then escalating privileges for administrator rights, dropping malware onto the server, and running an executable file, all without victims’ actions or authorizations. 
7.      Paul’s Security Weekly (securityweekly.com)
“Paul’s Security Weekly is an award-winning podcast, webcast, and security publication, publishing a number of weekly shows focused on recent security events, enterprise security, and interviews with professionals in the field” (SecurityScorecard, 2017).  Paul’s Security Weekly provides insight and current security news that might not be covered by other security organizations.
8.      The Security Ledger (securityledger.com)
The Security Ledger is an independent news provider that publishes current news on security on the Internet of Thing and the external threats from malware to cyber-terrorism.  For the last two decades or so, I could see that the world is facing different threats, which were the cyber-terrorism.  This threat has increase due to the fact that there are more and more countries
Normally, all the credible sources provide accurate information about the threats and vulnerabilities.  However, if they found to be provided invalid or conflict information, I would double check the information with other sources, professors, or friends.  I think I would also write an email to the authors or the credible sources and ask them to verify the information that they posted.  Communication, as I have mentioned earlier has been integrated into the fast and easy platform for the human.  To reach out a business or a person, it is very easy now.  To exchange the idea or information, it is just a click.

Current threats in Cybersecurity

Hi,

My name is Hai Pham.  I am a software developer and I have been working in software development for almost 18 years. Although I have worked in software development, but many projects that I worked relate to security.  Therefore, I am trying to pursue a cybersecurity program to increase my knowledge in IT security.  In the long run, I really wanted to work in the IT Security field.  Hopefully, once I am done with my Cybersecurity field, I would have a chance to move from software development to IT Security or Cybersecurity field.

My blog's purpose is to talk about the current information security threats that happen in IT security in general.  It can be a current virus, cyber attack, ransomware attack, phishing attack, spy hardware, etc.  Life is constantly facing new security threats every day and it is wise to be able to know and stay alert with those threats so that we could "Mitigate it, eliminate it, transfer it, or accept it" (Shostack, 2014).

One crazy security threat from last month that really drew my attention was the tiny spy chip.  A report from CNBC  mentioned that "the Chinese government snuck a pencil tip–size spy chip into equipment from an Amazon and Apple component supplier " (McKinley, 2018).  The spy chip compromised America’s technology supply chain.  It impacted almost 30 US companies: including two major companies: Apple and Amazon.  We often see software attack, such as trojans, worms, viruses, and they are very common.  The spy chip that China created was a hardware attack.  This is not common, and I think this is a more complicated attack.  Hardware attacks are very hard to detect and potentially more devastating.

(BLOOMBERG BUSINESSWEEK, 2018)

According to the Bloomberg BusinessWeek Report, the chips were used for gathering intellectual property and trade secrets from the US companies.  I am surprised that the problem was found in 2015 by independent security investigators but the chip was not reported to the public until Oct 2018.  The chip is small like a grain of rice and had been inserted during the manufacturing process of the motherboard.  The main impact was “the microchip altered the operating system’s core so it could accept modifications. The chip could also contact computers controlled by the attackers in search of further instructions and code” (Bloomberg, 2018).

Summary of my blogs


Hai Pham - Week 12
Week 12 – Summary of my blog
The theme for my blog is Cybersecurity in Financial Service.  I chose this topic because I have been working for a financial services company and one of the top priority of the company is cybersecurity.  It is because the company keeps so much sensitive information such as customer personal information, proprietary information, monetary data, and these data so crucial to the company, to the customer that cannot be leak out.  If it does, the company would run into big problem such as damage reputation, financial lost, lawsuit and losing customers. 

All around my blog, all the topics were related to cybersecurity threats, data management, how to protect the data, most common threat to the financial security and the cybersecurity trend.

As it has been stated, financial institution hold both financial and personal confidential data and that was why it has been become one of the most targets for hackers to attack.  To prevent the attack or the loss of data, the companies have encrypted the data.  With encrypted data, the hackers have a very little chance to decrypt it and use it.

I have talked about different ways of data encryptions that financial institutions use the most.  The first technique that I mentioned was the Data Encryption Standard (DES) which used only 56 bit of key size to encrypted the data.  This method had some security holes so it has been implemented to have 168 bit, which is call Triple DES.  Then I talked about two other strong encryption methods, which were RSA and Blowfish that even have a strong encryption method that can secure the data more.

One of my blogs was talking about the most common way that hackers use to attack financial institution is Phishing.  Right after I talk about this, the WannaCry ransomware came out and it mainly use the Phishing method attack the PC’s users. 
Bottom line is financial institutions are the most victim for cyberattack.  Companies are fully aware of it but why there are still victims out there day after day?  Hackers are constantly finding the ways, smarter method to attack and so, financial companies need to keep their environment up-to-date with technology to protect themselves.

Blogging is a good way to share the thoughts to others.  When writing the blogs, it is required me to do some research to find out the facts and real examples about the topic that I am writing. This help me to broaden my knowledge.  Then I also have a chance to read other blogs and this definitely helps me with more useful information and thought that people share.

Cybersecurity Trend for 2017

Week 11 Blog – Hai Pham

Cybersecurity Trend for 2017 that company will focus to increase security for customers.
Target attack on entry point is one of the most popular attack nowadays.  As we can see now that many organization growing their services and businesses by using the third parties.  It is due to the time and cost saving, having larger resource network, gaining more expertise from third party, company can focus on their core products, having more flexibility and scalability.  However, beside those good and strong points of using third parties, the third party often have many security holes or week protections that so vulnerable and would very easy to become the victims for hackers to take advantage and attack.  With that, companies when working with third parties, they should also require much higher of security level before they should work with.

The current trend on security threat is less sophisticated malware and more on social engineering threat is happening now.  Cybercriminals are changing the method of attack by using the less simple and work but still affect more by using social engineering to attack.  The trend on the leading back show 75% incident on fraudulent with social engineering now and only 17% with malware.  Hackers switch to use a simple way with less effort and cost less but still making the same “profit”.  With that, financial institution will change accordingly to adapt with the threats on social engineering.

Compliance and Penetration testing are another key fields that financial institution should focus on.  Both compliance and Pen test increase the security and eliminate the risk of attack.

We might never have thought but insider operatives are actually the big threats.  Many employee can be exploited by criminals or even the third party.  Employee leak out data or information or sometime sell access to the criminals.   Once the hackers can get inside the network, they can steal or damage big things.

WannaCry

Hai Pham - Week 10

Last week, I was written about the cyberattack upon the phishing and this week, on May 12, a huge cyberattack with WannaCry ransomware and mainly, bad guys used Phishing technique for an attack. 
As of Monday, May 15 2017, the attack affect about 230,000 computers in 150 countries.  The main business got affect badly were telecommunication in Spain, health services such as Britain’s National Health Service, shipping company such as FedEx and airline such as LATAM Airline.  There were four main countries got hit badly by WannaCry ransomware were Russia, Ukranine, India and Taiwan. 

WannaCry attacked thru phishing emails and on PC only, not MAC.  Once user click on the link, it will install the malware into the PC and then it uses EternalBlue Exploit and DoublePulsar Backdoor to spread through the local networks and all remote host that has no recent updates from Microsoft.  WannaCry will take the control over the host computer and it asked for the victim to pay ransom to get back the control.  If the victims do not pay for the ransom, WannaCry will delete all the encrypted files.

Did WannaCry give Financial Institution a big concern?  I think it really did.  Financial Institutions often have many confidential data and they often encrypted it.  Just think about the case of the banks got infected by WannaCry virus and all the customer information such as name, address, SSN, bank account numbers, debt info, credit card numbers, and mortgages data are affected and the banks lost the control over to those data or those data got delete?  I think it is very bad.

The key thing I see here is: it is very important for every single company to think and look the cyber threat is a real critical problem and it needs to be handle with serious matter.  Focusing on other kind of business and neglect about the cyber security is a huge mistake in our current life and business nowadays.  Again, I think the idea of “prevention is better than cure” works perfectly for cyber security.

Phishing



With our current digital era, pretty much all businesses operate more and more business online.  It’s because the online service is fast, convenient, and we can reach out to do business with companies throughout the world.  However, beside the huge advantage of digital realm, it makes each of the business so vulnerable for cyberattack.

Phishing is one of the most popular attack for financial institutions.  Base on the 2016 Global Trend from Kaspersky Lab, “In 2016, the share of financial phishing increased 13.14 percentage points to 47.48% of all phishing detections”.  We can see the huge threats increase in 2016 and I think it will continue to grow more.

Phishing is a criminal act of using electronic communication to obtain the confidential information from people such as login id, password, credit card information, SSN, address, etc.  The most popular example that we often see from Phishing is email spoofing, which guide users open the email and start following the link and enter the personal information on the fake website that looks almost the same as the trusted bank or any trusted financial institutions.  Another example of phishing is the email contain the link to the website that has malware.

There is no way to stop or control Phishing and the only way that users can protect themselves is everybody should have some basic training and prepare for ourselves with some basic security awareness so when dealing or seeing Phishing attack, we know and stay away from it.
