Yet Another Encryption Scam

ZDNet reports that another encryption scheme has arisen to rear its ugly head using Windows 10 upgrade as the teaser. Hackers are targeting users attempting to upgrade to Windows 10 with ransomeware malware that encrypts files until a ransom is paid. The "bad guys" appear to be impersonating Microsoft in and an attempt to grab your money. 

Emails are being sent out tempting the email recipient with an attachment that is an installer that will allow them to get the new Windows 10 operating system sooner. What is making this scheme work is the fact that Microsoft is making users wait in queue for their turn to upgrade their systems. Impatience on the part of waiting users is causing plenty of heartache for those that succomb to the tempation of running the installer.

Once you download and open the attached executable file, the malware payload opens, and begins encypting data on the affected computer and locking you out of those files.

Typically you are required to pay the ransom using bitcoin which is much harder to track. And to make it even harder to track the bad guys, they are usually using the TOR network which makes it nearly impossible to trace.

Cisco research Nick Biasini said the malware payload, called CTB-Locker, is being delivered at a "high rate." "The functionality is standard however, using asymmetric encryption that allows the adversaries to encrypt the user's files without having the decryption key reside on the infected system." 

Ransomeware attacks have been on an increase since 2014 and is a quick and easy near-untraceable way to generate a lot of money in a very short time. So hackers are going to keep coming up with new ways to attack your systems. So beware of what you are clicking on and accepting, you may their very next victim!
