TMS5 Ransomware

The TMS5 Ransomware threat is strong enough to prevent its victims from accessing their own data. The encryption process of the threat impacts a wide range of files - documents, databases, pictures, archives, etc., and leaves them in an unusable state. As is usually the case with ransomware attacks, the operators of TMS5 also are financial motivate, using the locked files to extort money from the affected users or organizations.

Analysis of the TMS5 Ransomware has revealed that the threat is a variant of the previously identified Matrix Ransomware. When executed on the breached device, the TMS5 Ransomware will lock and encrypt the files stored there and replace their original names. The new file names will consist of an email address ('TomSoyer5@protonmail.com'), a unique ID string and a new file extension ('.TMS5'). A ransom note will be delivered to the infected systems as a file named '!TMS5_INFO!.rtf.'

The attackers state that the TMS5 threat uses a combination of the AES-128 and RSA-2048 crypto algorithms. They urge users who wish to receive the necessary decryption key and software tool for the restoration of the encrypted data to contact them via the provided email addresses - 'TomSoyer5@protonmail.com,' 'TomSoyer5@yahoo.com,' and 'TomSoyer5@aol.com.' The cybercriminals will only accept payments made using the Bitcoin cryptocurrency. In addition, they allow victims to send up to 3 files that are less than 5MB in size to supposedly be unlocked for free.

The full text of the ransom note is:
