1 distinct threat actor attributed by public researchers. Open in Mallory to see the full evidence chain and overlapping campaigns.
NimBo-C2 is an open-source project available on GitHub. It is a lightweight and straightforward command and control (C2) framework.
23 distinct techniques documented for this family, organized by ATT&CK tactic.
Encrypted implant configuration and strings using NimProtect ... Packing payloads using UPX and obfuscate the PE section names ( UPX0 , UPX1 ) to make detection and unpacking harder.
2 indicators attributed across vendor reports, sandbox runs, and researcher write-ups. Full values are available in Mallory.
File hashes (MD5, SHA-1, SHA-256) from samples and reports.
4 sources tracked across advisories, community write-ups, and news. New activity surfaces here as Mallory finds it.
Nimbo-C2 is listed in the IOC section as a C2 agent sample ('PfSvc.exe') associated with the observed activity.
Nimbo-C2 is an open-source remote access trojan (RAT) used for command and control, data collection, and exfiltration. It was observed in this campaign for initial access and data theft, though its use by Chinese APTs is rare and may indicate access handoff or multiple actors in the same environment.
An open-source command-and-control framework written with a Python server and Nim client for Windows and Linux. In this campaign it was implanted on a compromised machine and used as a trojan/C2 component.
A named C2 agent listed solely as an indicator of compromise; the advisory provides no further behavioral details.
