The Loki modification inherited various techniques from Havoc to complicate analysis of the agent, such as encrypting its memory image, indirectly calling system API functions, searching for API functions by hashes, and more. However, unlike the agent for Havoc, Loki was split into a loader and a DLL, where main functionality of the malware is implemented.
