Se7en is a dangerous ransomware variant belonging to the Babuk family. Once executed, it encrypts a victim’s files, appends the ".se7en" extension (e.g., 1.jpg becomes 1.jpg.se7en), and drops a ransom note titled "How To Restore Your Files.txt".
The Se7en ransomware operates by heavily encrypting local data and exfiltrating sensitive files. Its core characteristics include:
