In July 2024, Kaspersky researchers discovered the previously unknown Loki backdoor, which was used in a series of targeted attacks. By analyzing the malicious file and open sources, we determined that Loki is a private version of an agent for the open-source Mythic framework.
The newly discovered Loki agent is a Mythic-compatible version of the agent for another framework, Havoc. 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.
