crosslock
CrossLock ransomware was first observed in April 2023, targeting an IT services firm in Brazil using a double‑extortion approach—encrypting data and threatening to leak it publicly. Written in Go, it uses a hybrid encryption scheme combining ChaCha20 for file encryption with Curve25519 for key protection. Victims see their files renamed with the .crlk extension and ransom notes titled ---CrossLock_readme_To_Decrypt---.txt. The malware includes advanced techniques like Event Tracing for Windo
