New ransomware named CTB-Faker has been discovered that pretends to be CTB-Locker ransomware. The ransomware will use the same images and contain some of the same content; However, instead of encrypting files on a computer that it infects it will move the files into a password protected .zip archive located at C:\Users.zip. CTB-Faker ransomware will then demand a ransom payment of .08 bitcoins, which is around $50.00 USD, in order to obtain a password to retrieve the files.
CTB-Faker ransomware is primarily distributed through fake Adult web cam videos, including a video that claims to contain a striptease. If a malicious link on the fake Adult web cam profile is clicked it will cause a zip file to download, which is hosted by JottaCloud. When the .zip file is extracted and an executable is ran by the user, the ransomware will move all the files into a password protected .zip archive folder. The main installer will then execute a VBS file. This file will generate a fake graphic card error and won’t let victims view the striptease video. But, in the background, the fake CTB-Locker ransomware is creating a password-protected .zip archive located at C:\Users.zip. The password protected .zip archive that it creates will contain files that the ransomware claims to encrypt.
CTB-Faker ransomware will then use a lot of CPU resources to slowly move the files located in the C:\Users folder to the .zip archive that match the following file extensions:
.exe, .msi, .dll, .jpg, .jpeg, .bmp, .gif, .png, .psd, .mp3, .wav, .mp4, .avi, .zip, .rar, .iso, .7z, .cab, .dat, .data
Once the ransomware has built the .zip archive it will delete certain VBS and Batch files found in the C:\ProgramData folder and it will then reboot the computer. When Windows Desktop is restarted the user will be met with a ransom note on the desktop background or text file that demands the victim to pay roughly $50.00 USD via Bitcoins. The note claims that once the payment is made the victim must email them to get a password. The ransomware uses several email addersses, some with a history of Bitcoin activity and some with not. 2 email address that it may use are email@example.com and firstname.lastname@example.org.
The ransomware will leave ransom notes on the computer it infects located at C:\ProgramData\index.html, C:\ProgramData\your personal files are encrypted.txt, and C:\your personal files are encrypted.txt.
