- The group employs "double extortion" tactics, stealing sensitive data before encryption and using both system decryption and public data release as leverage .
- HKCERT has proactively contacted affected Hong Kong institutions to provide cybersecurity recommendations and urge activation of incident response procedures .
- Attacks follow a three-phase pattern: initial access via unpatched vulnerabilities, weak passwords, brute force, or phishing; lateral movement and data exfiltration; then encryption with ransom demands backed by data exposure threats .
