AN0133: Analytic 0133
Detects attempts to clear RDP/network history and modify network configuration artifacts through command execution, registry key deletion, firewall rule changes, and suspicious file deletions (e.g., Default.rdp, registry edits to Terminal Server Client keys).
Analyst context for executives and security teams
AN0133 is a Windows detection analytic focused on attempts to erase or alter traces of Remote Desktop Protocol (RDP) and network configuration activity. For leaders, the value is not just catching a cleanup command; it is validating whether the organization can see evidence tampering around remote access, firewall changes, registry deletions, and removal of files such as Default.rdp that may be important during incident response.
Executive priority
Prioritize this analytic where Windows remote administration and RDP are material to operations. It supports incident decision-making and audit readiness by testing whether teams can preserve and detect changes to artifacts commonly needed to reconstruct remote access activity. Because ATT&CK provides no tactic mapping, relationship context, or formal detection logic for this object, treat it as a control-validation prompt rather than a complete detection package.
Technical view
SOC and IR teams should validate visibility into Windows command execution, registry key deletion or modification affecting Terminal Server Client artifacts, firewall rule changes, network configuration changes, and suspicious deletion of RDP-related files such as Default.rdp. The analytic is scoped to Windows. Since no official detection query is supplied, teams should build or review local logic around combinations of command-line activity, registry operations, file deletion events, and firewall configuration changes, then tune against legitimate administrative activity.
Likely telemetry
- Windows process creation and command-line telemetry
- Windows registry modification and deletion telemetry, especially Terminal Server Client-related keys
- Windows firewall rule change events or equivalent host configuration logs
- File deletion telemetry for RDP-related artifacts such as Default.rdp
- Endpoint detection and response alerts or raw endpoint event data
Detection direction
- Confirm that command execution, registry activity, firewall changes, and file deletion events are collected from relevant Windows systems.
- Correlate artifact-clearing behavior with recent or suspicious remote access activity when local telemetry allows, rather than alerting on a single benign administrative action alone.
- Tune for known administrative scripts, helpdesk workflows, system hardening tasks, and endpoint cleanup tools that may legitimately modify firewall rules or remove RDP history artifacts.
- Validate retention: these events may be most useful after an incident, so short log retention can create a major blind spot.
- Because MITRE provides no official detection logic for AN0133, document local assumptions, event IDs, data sources, and test cases used to operationalize it.
Mitigation priorities
- Restrict and govern who can modify Windows firewall rules, registry keys, and remote access configuration artifacts.
- Use change management or privileged access controls for administrative actions that alter network or RDP-related settings.
- Ensure endpoint logging and retention are sufficient to preserve evidence of registry deletion, command execution, and file deletion.
- Review RDP use and remote administration policy where these artifacts are operationally important.
- Include this analytic in IR readiness exercises to verify that teams can identify possible evidence-clearing behavior during Windows investigations.
Analyst notes and limits
This object is a detection analytic, not a technique description. The supplied ATT&CK fields identify Windows scope and describe behavior involving command execution, registry key deletion, firewall changes, and RDP/network history artifact deletion. No tactic, related technique, or official detection query was supplied, so implementation must be derived and tested locally.
The official detection field is not provided, and no relationships or tactic mappings were supplied. This take does not infer attribution, active exploitation, impact, or coverage. Local environment baselines are required to separate suspicious artifact clearing from approved administration.

How security teams should use this page
Treat this object as behavior context, not an attribution claim. Validate the related groups, software, data sources, and mitigations against official ATT&CK relationships and your own telemetry before making control-coverage decisions.
