This tool deploys decoy canary files in critical system directories to provide early warning against ransomware attacks. Utilizing Python's watchdog library, it monitors for any read, modify, rename, or delete operations on these decoy files. Detection triggers immediate alerts via multiple channels (Email, Slack, Syslog), helping security teams identify and respond to malicious activity before full data encryption occurs. It serves as a crucial detection layer in a layered security defense.

This tool builds a tamper-evident, append-only log chain using SHA-256 hash chaining. By incorporating the previous entry's hash into the current entry, any modification to an old log entry will invalidate all subsequent hashes, enabling pinpoint tamper detection. It supports various log formats (syslog, JSON, plain text) and is essential for compliance, digital forensics, and verifying log authenticity in security operations.
