This detection rule is designed to identify potential persistence mechanisms employed by attackers using the HtmlHelp Author registry key on Windows systems. Specifically, it triggers when changes are made to the registry path: \Software\Microsoft\HtmlHelp Author\Location or \Software\WOW6432Node\Microsoft\HtmlHelp Author\Location. By modifying this key, attackers can ensure their malicious payloads execute each time a specific help file is accessed, thus persisting across system reboots. Given that this behavior is uncommon in legitimate application usage, any changes detected at these registry keys are considered suspicious and warrant further investigation. The rule utilizes Windows registry logging to monitor and alert on any unauthorized modifications, contributing to enhanced detection of persistence tactics often associated with malware activities.
