Detects instances where a legitimately signed executable located in protected system directories (System32, SysWOW64, Program Files) loads a DLL module from common user-writable directories (Temp, AppData, Public, ProgramData). This behavior is characteristic of DLL sideloading, where an adversary leverages a trusted binary to execute malicious code contained in a side-loaded DLL.
