What is Saturn ransomware
The Saturn ransomware is a variant of crypto viruses (malware that encrypt personal files and demand a ransom). It affects all current versions of MS Windows OS such as Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. This ransomware uses strong encryption method to eliminate the possibility of brute force a key which will allow to decrypt encrypted photos, documents and music.
When the Saturn ransomware infects a PC system, it uses system directories to store own files. To run automatically whenever you turn on your PC, Saturn ransomware creates a registry entry in Windows: sections HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ Run, HKCU \ Software \ Microsoft \ Windows \ CurrentVersion \ RunOnce.
