Stryker-Pattern Mass Device Wipe / Destructive Intune Admin Actions
Detects mass device wipe, retire, or delete operations performed via Microsoft Intune, inspired by the Stryker/Handala attack. This rule combines five detection signals: static velocity threshold, bulk destructive actions from a single operator, first-time operator detection, UEBA anomaly correlation, and ML anomaly detection. Operations are categorized into Tier 1 (critical, zero baseline activity like wipe/retire) and Tier 2 (high, legitimate IT ops activity like device delete, subject to velocity and ML thresholds). Severity escalates based on the number of overlapping signals.
