The detection rule 'Detect HTML Help Renamed' identifies potentially malicious activity involving the renaming of 'hh.exe' (HTML Help executable) and its execution of Compiled HTML Help (CHM) files. This technique is particularly relevant given that attackers may rename 'hh.exe' to execute harmful scripts concealed within CHM files, which can lead to arbitrary code execution. The detection leverages data from Endpoint Detection and Response (EDR) systems by monitoring process names and their original file names to highlight discrepancies in expected execution patterns. If confirmed as malicious, such activity can enable attackers to escalate privileges or achieve persistence within the target environment, thus representing a critical security threat that requires prompt investigation and mitigation measures.
