The U.S. Cybersecurity and Infrastructure Security Agency (CISA) stated on Monday that there is “no indication” the recent cyber breach at the U.S. Treasury Department has affected any other federal agencies. This followed a report that Chinese hackers compromised several computers at the Treasury, stemming from a breach at cybersecurity contractor BeyondTrust.
While BeyondTrust confirmed that a limited number of its clients were affected, the company has not provided further details regarding which clients may have been impacted. The forensic investigation into the breach is still ongoing, and BeyondTrust has yet to confirm additional details about the scope of the attack.
Reports have suggested that the hackers specifically targeted the U.S. Treasury office responsible for administering economic sanctions, likely aiming to access information about Chinese entities under consideration for U.S. financial sanctions. This attack is part of an ongoing series of cyber incidents attributed to Chinese state-sponsored actors.
Republican lawmakers have called for a briefing on the incident. In response, Chinese Embassy spokesperson Liu Pengyu dismissed the claims, calling the reports “irrational” and part of “smear attacks” against China.
