Advanced protection system that detects and blocks WannaCry, Petya, and emerging ransomware variants before file encryption begins. Includes automatic rollback capabilities.
Identifies ransomware by monitoring file encryption patterns, mass file modifications, and shadow copy deletions.
Blocks WannaCry, Petya, Ryuk, REvil, and other known ransomware families through signature-based detection.
Stops file encryption processes immediately upon detection, preventing data loss before it starts.
Restores encrypted or modified files from secure snapshots taken before the ransomware attack.
Quarantines infected devices to prevent lateral movement and network-wide ransomware propagation.
Uses AI to identify new ransomware variants by analyzing behavior patterns instead of signatures.
Rapid modification of multiple files with suspicious extensions like .encrypted, .locked, .crypted
Attempts to delete Windows Volume Shadow Copies to prevent file recovery
Generation of README or DECRYPT_INSTRUCTIONS files in multiple directories
Attempts to spread via SMB shares, RDP connections, or email attachments
Outbound connections to command-and-control servers for encryption key exchange
Malicious code injection into legitimate processes to evade detection
When NISSI detected the "Ransom.WannaCry.Variant" attempting to encrypt documents on the CEO's MacBook Pro, it immediately quarantined the malware, blocked network connections to the C2 server, and alerted the security team—all within 103 milliseconds. The device was marked "at risk" with a security score drop to 62%, and auto-remediation prevented any data loss.
Stop ransomware attacks before encryption starts with AI-powered behavioral detection and automatic rollback.
