Which THREE indicators are commonly associated with ransomware activity in Microsoft Sentinel threat hunting?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Network connections to known C2 infrastructure
Ransomware activity commonly involves three indicators: network connections to known C2 infrastructure (command and control communication), mass file rename or extension changes (file encryption), and scheduled task creation on multiple endpoints (persistence mechanism). Option A (unusual DNS queries to known safe domains) is not typical for ransomware, and option C (excessive failed logon attempts) is more indicative of brute-force attacks. Therefore, the correct options are A, D, and E.
