UNC4487  (Back to overview)


UNC4487 is a threat actor that targeted Ukrainian government officials by compromising a Ukrainian auto insurance website essential for official travel. This attack facilitated the distribution of the MATANBUCHUS malware, which was used to monetize access to infected systems. Mandiant later identified additional malware samples, referred to as ChillyHell, linked to UNC4487 through the reuse of a code signing certificate associated with MATANBUCHUS. The group's activities highlight a focus on exploiting critical infrastructure for financial gain.
