Cryptolocker Ransomware: What You Need To Know
We are seeing a new version of Crypto Locker Ransomware infecting computers and encrypting files so that you cannot access them. A message comes up as shown in the image below demanding $300 to be paid in order to get the files back.
Here is the full link to the Malwarebytes report on this virus http://blog.malwarebytes.org/intelligence/2013/10/cryptolocker-ransomware-what-you-need-to-know
If you encounter this virus on a work or home machine, turn it off immediately. Do not click on anything to close it. They try to panic you to click on “Close” buttons which are really an “Ok, Infect My Computer” button. Simply turn off the power immediately and contact an IT support person.
We recommend enabling strict filters on any and all firewalls in both your home and office, which may block some valid HTTPS sites such as banking sites but it’s safer than letting this new trojan/virus into your computer systems. The infection is also “network aware” which means that if an infected user has access to a shared folder on a server or another workstation, that user will cause all shared files to become encrypted and unrecoverable as well.
The trojan infection is coming from infected web sites. The links may come in via email or on social media sites. So be very cautious about ANY web links. As we always recommend the sender should clearly identify themselves, you should know the sender and the purpose of the link(s) sent. In any case – it’s still best to ignore them and DO NOT click on any links you receive without first calling and verifying the sender and the link is legitimate.
