The Cybersecurity and Infrastructure Security Agency (CISA) said Monday that there is “no indication” other federal agencies were impacted by the recent breach at the Treasury Department. The Treasury Department revealed last week that Chinese state-sponsored actors had hacked into the agency’s workstations in early December and accessed unclassified documents.

Chinese hackers exploited BeyondTrust API keys in a major Treasury cyberattack; CISA confirms no wider federal impact.

The list serves as a warning to American companies and organisations about the risks of doing business with Chinese entities. While inclusion does not mean an immediate ban, it can add pressure on the US Treasury Department to sanction the firms.
