Sepsis Ransomware – Distribution Ways
Sepsis ransomware might spread its infection in various ways. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer system will become infected.
In the below screenshot you can view the detection of the Sepsis payload file made on the VirusTotal service:
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.

The note of the Sepsis ransomware virus states that your files are encrypted. You are demanded to pay money to allegedly restore your files. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted once again.
Sepsis Ransomware – Encryption Process
What is known for the encryption process of the Sepsis ransomware is that every file that gets encrypted will become simply unusable. All encrypted files will receive the “.[Sepsis@protonmail.com].SEPSIS” extension appended to them. Some researchers argue whether the AES encryption algorithm is used for the file encryption.
The full list with the targeted extensions of files which are sought to get encrypted is currently unknown. However, if it becomes known, it will be posted here as an update to the article.
The files used most by users and which are probably encrypted are from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The Sepsis cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the above-stated command is executed that will make the effects of the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data.
