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.
