The reuse paths just imported the existing resources and reported success — they never checked whether the existing services were actually doing their job.\n\n1. **GuardDuty reuse.** If the existing detector was suspended, or set to the slower 6-hour publishing cadence instead of the baseline 15-minute one, or otherwise misconfigured — Hulumi never noticed. The deployment succeeded with a misleadingly-positive `guardDutyDetectorId` output as if the baseline were active.\n2. **Security Hub reuse.** Although the account import was read-only, Hulumi unconditionally created the CIS / NIST `StandardsSubscription` resources with default delete behaviour. Pulumi then treated those subscriptions as its own — a later `pulumi destroy` of the stack would call `BatchDisableStandards`, unsubscribing the account from CIS / NIST compliance monitoring even on accounts that had ","public_affected_ranges":["< 1.4.0"]}],"null_published_at":"2026-11-07T07:07:39.819Z","source_updated_at":"2026-06-10T13:39:01.000Z","source_disclosed_at":"2026-06-10T13:38:59.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-06T15:13:31.161Z"}],"next_cursor":null,"snapshot_revision":"42594"}
