Analysis Summary
A new ransomware called SNAKE that is targeting networks and aiming to encrypt all of the devices connected to it. The ransomware contains a level of routine obfuscation not previously and typically seen coupled with the targeted approach.When started Snake will remove the computer’s Shadow Volume Copies and then kill numerous processes related to SCADA systems, virtual machines, industrial control systems, remote management tools, network management software, and more.
It then proceeds to encrypt the files on the device, while skipping any that are located in Windows system folders and various system files.
When encrypting a file it will append a ransom 5 character string to the files extension. For example, a file named 1.doc will be encrypted and renamed like 1.docqkWbv.
When done encrypting the computer, the ransomware will create a ransom note in the C:\Users\Public\Desktop folder named Fix-Your-Files.txt. This ransom note contains instructions to contact a listed email address for payment instructions.
