FlatChestWare – another Hidden-Tear based virus

Ransom note by FlatChestWare ransomware virus

FlatChestWare is a file-encrypting virus that is based on the HiddenTear project.[1] This Trojan uses AES-256 cryptography and appends .flat file extension to each of the targeted files. After successful data encryption, it runs a program window with a ransom note where users are asked to pay $250.

After the infiltration, FlatChestWare virus shows a fake Windows Update window that looks like ordinary User Account Control (UAC) prompt. This trickery tries to make victims click an obfuscated button to launch malicious activities:

Windows Update
Restart your computer to finish installing important updates
Windows can't update important files and services while the system is using them. Make sure to save your files before restarting.
[“Restart now” button] [“Postpone” button]

Undoubtedly, the majority of users agree to install updates by clicking “Restart now” option. However, instead of getting important updates, users allow malware to delete Shadow Volume Copies and other cause other system changes. Therefore, malicious activities start if a user is tricked into hitting the button.

As soon as the computer is rebooted, FlatChestWare delivers a ransom-demanding message. Crooks inform about encrypted image, audio, video, text and other popular files. It is said that only their decryption software can help victims to restore their files.

HiddenTear, as well as the majority of its variants, is decryptable. Thus, you might be able to restore your files without paying the ransom. However, first of all, you should remove FlatChestWare from the PC. Do not follow criminals’ orders to disable your anti-virus. You should do the opposite.
