Description
The following analytic detects the deletion of registry keys by non-critical processes. It leverages Endpoint Detection and Response (EDR) data, focusing on registry deletion events and correlating them with processes not typically associated with system or program files. This activity is significant as it may indicate malware, such as the Double Zero wiper, attempting to evade defenses or cause destructive payload impacts. If confirmed malicious, this behavior could lead to significant system damage, loss of critical configurations, and potential disruption of services.
Detection logic
Detection requirements
- Platform
- Windows
The rule states no platform. This is derived from the ATT&CK technique it maps to.
- Log source category
- sysmon_eventid_1_and_sysmon_eventid_12
Known benign triggers
- This detection can catch for third party application updates or installation. In this scenario false positive filter is needed.
MITRE ATT&CK mappings
0 exclusive techniques.This is coverage no other published rule has; it is not this rule's total technique count.
