Threat Database Ransomware SepSys Ransomware

SepSys Ransomware

The SepSys Ransomware is a new data-locking Trojan, which is likely to ruin the day of many users worldwide. This ransomware threat is designed to lock a long list of filetypes to ensure maximum damage on the compromised machine. All documents, images, audio files, videos, archives, presentations, databases, spreadsheets, and other common filetypes will be locked securely with the help of an encryption algorithm. The locked files will be unusable until the user unlocks them using the appropriate decryption key.

Propagation and Encryption

Mass spam email campaigns are the most popular propagation method in regard to the spreading of ransomware threats. The targeted users would receive an email that contains a corrupted attachment and a fake message urging them to launch the attached file. Needless to say, users who comply will expose their systems to the SepSys Ransomware. Fake application updates, malvertising campaigns, pirated media, and applications are other commonly utilized infection vectors. The SepSys Ransomware will scan the system it has penetrated, and then begin the encryption process. The names of the locked files will be changed because the SepSys Ransomware adds a new extension – 'sepsys.' For example, a file that was bearing the name 'first-steps.jpeg' will be renamed to 'first-steps.jpeg.sepsys' when the SepSys Ransomware encrypts it.

The Ransom Note

The ransom note that the SepSys Ransomware drops is called 'README.html.' The attackers' note is rather brief. In the note, the creators of the SepSys Ransomware state that they demand to be paid $100 in the shape of Bitcoin. There is an email address for the users who would like to get in touch with the attackers and receive further information – ‘'

It is best to avoid contacting cybercriminals like the ill-minded actors behind the SepSys Ransomware. They are unlikely to help or provide you with a decryption key, even if you pay them. This is why, instead, you should remove the SepSys Ransomware from your computer with the help of a genuine anti-malware application.
