What it detects

This rule flags Windows image-load events where roboform.dll or roboform-x64.dll is loaded, which can indicate DLL sideloading or related execution manipulation around RoboForm components. Attackers may abuse search-order or side-loading behavior to load a malicious DLL from an unexpected location. The detection relies on image-load telemetry (ImageLoaded) and correlates it with the loaded module and specific parent executable names while excluding known main-path patterns.
