What it detects

This rule detects rundll32 loading SnippingTool.dll from a KeyStore folder and invoking its Main export, the execution technique used by the SnipBot variant of RomCom malware. Proxying execution of the malicious DLL through the trusted rundll32 binary helps the loader evade application controls.
