BASS-FES (BitchASS File Encryption System) is a ransomware-type cyber threat that is based on the HiddenTear project. The virus uses AES cryptography and appends the .basslock file extension to the encrypted files. Then it drops a ransom note called “the BASS the File the Encryption the Service Notice.txt” on the affected computer’s desktop. The ransom payment is demanded in 1 BitCoin.
BASS-FES ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary.
That ransom message appears after encryption is completed and reads the following:
“File Recovery Notice by BitchASS File Encryption System (BASS-FES)
Your files have been successfully encrypted and backuped in the cloud storage by BASS File Encryption System.
If you want to recover your files, please send 1 BTC to the following adress:
If you sent 1 BTC to the adress, email at email@example.com with your Bitcoin adress.”
You should NOT under any circumstances pay the ransom. Your files may not get restored, and nobody could give you a guarantee for that. Plus, giving money to cybercriminals will likely motivate them to create more ransomware viruses or commit other crimes. We recommend using Max Total Security with ” Max Crypto Monitor ” to keep your pc safe and use its Data restore feature if ever something likes this happens.
