CISA says ‘no indication’ other US government agencies affected in Treasury hack

• The US Treasury Department suffered a cyberattack in late 2024
• CISA has confirmed it does not believe any other agencies were affected
• The hack has been attributed to a Chinese threat actor

The Cybersecurity and Infrastructure Security Agency (CISA) has confirmed that there is currently ‘no indication’ that any other federal government agencies were impacted by the recent suspected state-sponsored hack against the US Treasury Department.

The December 2024 hack was declared a ‘major incident’, as key systems were left vulnerable, with the attack resulting in stolen documents and breached systems, and an initial agency assessment concluding the attack was carried out by a ‘China-based Advanced Persistent Threat Actor’, officials said.
