.SYS ransomware is another addition in malware encrypting personal files of victims and asking them to pay ransom money to get the files back. The targeted files become inaccessible until the demanded ransom money is not paid. The extension of the infected files gets changed with a 16 character hexadecimal string filename. For example 1D674D004NNB70F474DFF1B265DAB987.SYS. The ransom note is stored in every folder containing the files. The ransom demanding note is named as “_HELP_INSTRUCTION.TXT”.

The related ransom note tries to convince the victims to pay the ransom money as early as possible within the given timeframe. The ransom note contains multiple emails ID such as,,, or It also warns and threats the victims to not use any third-party applications for file decryption. It is unknown about the encryption cryptography used by .SYS ransomware. Most possibly, it uses the combination of symmetric and asymmetric encryption method.
