What is Sepsis ransomware? And how does it execute its attack?
Sepsis ransomware is a file-encrypting threat that appears to be a new variant of the infamous Globe ransomware as its ransom note and file markers are almost identical to other variants of Globe ransomware like Decoder ransomware and Blocking ransomware. Just like its predecessor, Sepsis ransomware is designed to encipher targeted files that are mostly user-generated like images, videos, documents, audio files, database, and many more. According to security experts, this crypto-virus uses the AES encryption algorithm in encrypting files.
Before it starts the encryption, Sepsis ransomware will drop additional files into the system as well as modifies some entries in the Registry so it can run on every system boot. Once all of these things are covered, it will begin to encrypt the files and append the “.[[email protected]].SEPSIS” extension to each one of the affected files. After that, it places a file named “Info.hta” that contains the ransom note. It states:
“Welcome to Sepsis Ransomware!
All your files have been encrypted!
All your files have been encrypted due to a security problem with your PC. If you want to restore them, write us to the e-mail [email protected]

According to its ransom note, you are demanded to pay the ransom to allegedly recover your files. However, you should not, under any circumstances, pay the ransom as it would only be a total waste of money for there really is no guarantee that these crooks will give you the decryptor. The best thing you can do is to ensure the removal of Sepsis ransomware from your computer. Once you’ve accomplished that, you can try other alternative options to recover your files.
