Monitors for cases where the WDT status is set to disabled, which may signal tampering or exploitation by a threat actor. The status could also be suspended vice disabled. This could look like [x-opencti-watchdog:active = false] in STIX

| DE-0003.11 | Watchdog Timer (WDT) for Evasion | By modifying watchdog parameters or who “pets” them, an adversary shapes what evidence survives. Extending or disabling timeouts allows long-running processes to operate without forced resets that would expose abnormal CPU or power usage; conversely, shortening windows or relocating the petting source to a low-level ISR can induce frequent resets that wipe volatile traces, break correlation in logs, and explain anomalies as “spurious reboots.” In both directions, the watchdog becomes a timing tool for hiding activity rather than a guardrail against it. | |
