HijackLoader/CastleLoader DLL Side-Loading from Non-Standard Directory
This rule detects when a signed process loads a DLL file from common user-writable directories (AppData, ProgramData, Public, Downloads). It further filters by verifying that the DLL is located in the same directory path tier as the executing process, which is a common indicator of side-loading or DLL hijacking activity where an attacker places a malicious DLL alongside a legitimate executable.
