Woodgnat Backdoor.Mistic / ModeloRAT Reflective DLL In-Memory Injection

Detects in-memory DLL injection where a module is loaded into process memory without a backing file path on disk (action_module_path is null or empty). This technique, often referred to as reflective DLL injection, is used to evade detection. The rule further refines detection by flagging cases where the hosting process itself originates from an unusual or user-writable path, which can be indicative of DLL sideloading. This behavior is consistent with malware like Backdoor.Mistic or ModeloRAT, deployed by threat groups such as Woodgnat (KongTuke).
