This rule detects when a legitimate signed executable loads a DLL from a non-standard or user-writable directory (e.g., AppData, Temp, ProgramData). This behavior is characteristic of DLL search order hijacking, a technique used by various backdoors, including MiniJunk, to gain persistence or execution within a trusted process.
