Analyst context for executives and security teams
This detection strategy is tied to ATT&CK technique T1546.017, Udev Rules, where Linux device-event rules can be abused for persistence or privilege escalation. For leaders, the decision value is not the rule syntax itself; it is whether Linux systems that matter to operations have enough file, process, and change-control visibility to prove that udev rule changes are authorized and investigated quickly.
Executive priority
Prioritize this where Linux hosts support critical services, administrative infrastructure, or regulated workloads. The business question is whether security teams can distinguish legitimate device-management changes from persistence mechanisms, and whether incident responders can quickly validate how a suspicious udev rule appeared, what it executed, and whether it affected privileged execution paths.
Technical view
ATT&CK provides no official detection text for DET0375, so teams should derive coverage from the related technique context: Linux udev rules used for persistence and privilege escalation. SOC and IR teams should validate monitoring for udev rule file creation/modification, suspicious execution triggered from device events, and correlation with privileged user activity or change-management records. Detection engineering should focus on high-signal changes to udev configuration locations and unexpected commands or scripts referenced by rules, while accounting for legitimate administrator, package, and hardware-management activity.
Likely telemetry
- Linux file integrity or file modification events for udev rule locations
- Linux process execution telemetry showing commands or scripts launched by udev-related activity
- Privilege and account activity logs associated with administrative changes
- Endpoint detection or host audit logs from Linux systems
- Change-management, package-management, or configuration-management records for authorized udev updates
Detection direction
- Validate that Linux telemetry exists for both file changes and resulting process execution; file-only monitoring may miss whether a rule actually launched content.
- Tune detections around unauthorized or unusual udev rule creation/modification, especially where rules reference scripts, interpreters, or paths outside expected administrative baselines.
- Correlate alerts with change windows, package installation activity, hardware management workflows, and known configuration-management actions to reduce false positives.
- Prioritize investigation when udev changes align with persistence or privilege-escalation objectives, such as privileged execution context or unexpected post-change process activity.
- Document coverage gaps explicitly because the ATT&CK detection strategy object does not provide an official detection analytic.
Mitigation priorities
- Establish an approved baseline for udev rules on important Linux systems and monitor drift from that baseline.
- Restrict administrative write access to udev configuration paths using standard Linux permission and privileged-access controls.
- Require change control for udev rule modifications on production or sensitive systems.
- Ensure incident response playbooks include review of udev rules when investigating Linux persistence or privilege escalation.
- Use host logging and configuration management evidence to support audit readiness and post-incident scoping.
Analyst notes and limits
This take is based on DET0375 and its relationship to T1546.017 Udev Rules. The detection strategy object itself has no official description, detection text, tactics, or platform field; the Linux, persistence, and privilege-escalation framing comes from the related ATT&CK technique context supplied in the relationship.
ATT&CK fields supplied here do not include a specific analytic, data source list, command examples, mitigations, procedures, or known threat use. Local Linux architecture, logging depth, configuration-management practices, and authorized udev use must determine final detection logic and prioritization.
