What is Sinobi ransomware?
The malware analyzed by WhiteDefender, a research and development firm specializing in ransomware security, is Sinobi ransomware.
Sinobi ransomware not only encrypts files but also appends the extension (.SINOBI). For example, a file named "file.jpg" will be renamed to "file.jpg.SINOBI," and "2.xlsx" will be renamed to "2.xlsx.SINOBI." It also creates a ransom note (README.txt) containing instructions and changes the background image.

The ransom note is a note containing instructions that require users to follow these instructions.
