Les# Ransomware

The Les# Ransomware appears to target Russian-speaking users since it supplies all of its victims with a ransom note written in Russian. However, no one can be sure that the propagation campaign is limited to Russian regions, and users worldwide should make sure to keep their computers protected from threats like the Les# Ransomware sufficiently.

Failing to stop the attack of a file-encryption Trojan may end up costing you a lot since these threats are excellent when it comes to corrupting a large fraction of the user’s data by using a strong encryption routine. All files that the Les# Ransomware locks will be marked with the ‘.les#’ extension and the ransomware also may use base64 encoding to scramble the original filename.

The Les# Ransomware’s ransom note is stored in the file ‘как расшифровать файлы les#.TXT’ and it tells victims that they have to purchase the decryptor in exchange for Bitcoin. They also warn all affected users that they will lose 24 files every 24 hours and that the price of the decryptor will increase by 30% every 24 hours.

It is unlikely that the Les# Ransomware will wipe out any of your files, and you should not worry about the increased price since you should never agree to send money to cybercriminals. The suggestion to victims of the Les# Ransomware is to eradicate the file-locker with the help of a suitable anti-malware application. When they complete this step, they can proceed to try the services of data recovery tools that might enable them to get some of their files back.
