The following analytic identifies path traversal command-line execution. This technique was seen in malicious document that execute malicious code using msdt.exe and path traversal technique that serve as defense evasion. This TTP is a good pivot to look for more suspicious process and command-line that runs before and after this execution. This may help you to find possible downloaded malware or other lolbin execution.

The SPL above uses the following Macros:

:information_source: windows_command_and_scripting_interpreter_path_traversal_exec_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

How To Implement

To successfully implement this search you need to be ingesting information on process that include the name of the process responsible for the changes from your endpoints into the Endpoint datamodel in the Processes node. In addition, confirm the latest CIM App 4.20 or higher is installed and the latest TA for the endpoint product

Known False Positives

Associated Analytic Story


Risk Score Impact Confidence Message
90.0 90 100 A parent process $parent_process_name$ has spawned a child $process_name$ with path traversal commandline $process$ in $dest$

:information_source: The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
