What it detects

This rule detects loading of jli.dll from a user-writable or temporary directory, the DLL sideloading vector observed in the Matanbuchus and AstarionRAT chain where a signed Java launcher was abused to load a malicious jli.dll. Placing an attacker DLL beside a trusted executable causes it to be loaded with the host binary's trust. Loading jli.dll from outside a legitimate Java runtime path indicates search-order hijacking.
