How to Detect Ransomware

This Arctic Wolf threat report analyzes the evolving ransomware threat landscape, noting increasing ransom demands, widespread use of double/triple-extortion, and that most intrusions begin via externally exposed systems or identity-focused attacks. It outlines common initial access methods (external remote access, known unpatched vulnerabilities, phishing, compromised credentials), lateral movement techniques (pass-the-hash, fileless malware, Kerberoasting), and provides detection and mitigation guidance including vulnerability management, MFA and identity controls, endpoint security, holistic visibility/monitoring, 24×7 managed detection and response, and incident response planning.
