This detection identifies the deletion of files within the AutomaticDestinations folder, located under a user’s AppData\Roaming\Microsoft\Windows\Recent directory. These files are part of the Windows Jump List feature, which records recently accessed files and folders tied to specific applications. Each .automaticDestinations-ms file corresponds to a program (e.g., Explorer, Word, Notepad) and can be valuable for forensic analysis of user activity. Adversaries may target this folder to erase evidence of their actions, such as which documents or directories were accessed during a session. This type of deletion is rarely seen during normal user activity and may indicate deliberate anti-forensic behavior. When correlated with suspicious logon events, RDP usage, or script execution, this activity may represent an attempt to cover tracks after data access, lateral movement, or staging for exfiltration. Detecting removal of these artifacts can highlight post-compromise cleanup efforts and help analysts reconstruct attacker behavior.

how_to_implement: To successfully implement this search, you must ingest logs that include the process name, TargetFilename, and ProcessID executions from your endpoints. If you are utilizing Sysmon, ensure you have at least version 2.0 of the Sysmon TA installed.
known_false_positives: False positives will be present, filter as needed or restrict to critical assets on the perimeter.

Indicators

Each row is a field, operator, and value that the rule matches. The corpus column counts how many other rules in the catalog look for the same combination: high numbers point to widely-used, community-vetted indicators. Blank or 1 shows that the indicator is specific to this rule.
