LionTail

LionTail is a malware framework associated with APT34 (OilRig). The provided content describes it as part of OilRig’s tooling used to sustain long-term, low-visibility access during intrusions. In a reported 2023 campaign against undisclosed Middle Eastern government entities, OilRig used the LIONTAIL framework alongside PowerShell backdoors and keyloggers, with LionTail providing custom loaders and memory-resident shellcode. The same activity employed DNS tunneling, HTTP communications, scheduled tasks, macros, and PowerShell scripts for persistence and stealth. The malware is therefore linked to espionage-focused operations targeting government entities in the Middle East and is characterized by in-memory execution and support for covert persistence and command-and-control tradecraft.
