What it detects

This rule detects a Run key persistence value whose data references a DLL located under a user Documents folder, matching the Rhadamanthys stealer persistence that pointed an autorun entry at a DLL in the Documents directory. Autorun entries loading a DLL from a user-writable location strongly indicate malicious persistence rather than legitimate software.
