1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
“Elements of COFFLoader also suggest custom features for use after a system is compromised.”
2 distinct techniques documented for this family, organized by ATT&CK tactic.
With process injection becoming a prevalent technique for embedding code into legitimate processes... The latest innovation... is the use of Beacon Object Files (BOFs), which execute lightweight payloads directly into an existing process’s memory.

2 sources tracked across advisories, community write-ups, and news. New activity surfaces here as Mallory finds it.
Loader tooling whose elements were identified in the campaign's decoded payload, suggesting customized post-compromise capabilities. The content does not establish deployment of a separate, standalone COFFLoader payload.
Elements of COFFLoader were identified in the analyzed payloads. The researchers interpret its APIs as evidence that the malware author used a custom Beacon Object File to implement post-exploitation functionality.
