US Treasury announced a cyber attack from China.

The US Treasury Department informed Congress about a hacker attack from China on the agency's workstations. This was reported by several international media outlets, including Voice of America.

CNN reports that the attackers used stolen keys for remote access to certain Treasury workstations and accessed non-classified documents.

"Based on the available indicators, the incident was carried out by a state-sponsored Chinese actor, which poses a persistent and sophisticated threat (Advanced Persistent Threat, APT)," wrote Aditi Gardikar, assistant secretary of the US Treasury, in a letter to lawmakers.

The number of workstations that were hacked and the specific documents the hackers may have accessed are not disclosed. According to CBS, Treasury officials assured that "there is currently no evidence that the threat continues to exist".

"The Treasury Department takes all threats to our systems and the data they hold very seriously. Over the past four years, the Treasury Department has significantly strengthened its cybersecurity, and we will continue to work with both private and public partners to protect our financial system from threats," the statement from the US Treasury press service reads.

Currently, department officials are cooperating with law enforcement and the Cybersecurity and Infrastructure Security Agency (CISA) on investigating the incident.

BBC reports that a spokesman for the US Treasury told the publication that the Treasury learned about the hacker attack from the company BeyondTrust on December 8. The company BeyondTrust first detected suspicious activity on December 2, but it took three days for the company to determine that it had been breached.

China denied any involvement in the breach, according to a statement from the Chinese Ministry of Foreign Affairs reported by France-Presse. Chinese Foreign Ministry spokeswoman Mao Ning stated that Beijing "has always opposed all forms of hacker attacks, and we even more oppose the spreading of false information about China for political purposes".

The largest hacker attack on state registers in Ukraine

We remind you that on the eleventh day after the largest hacker attack by the Russians, the first three registers in Ukraine resumed operations.

As reported by Glavkom, due to the malfunction of some state registers, service centers of the Ministry of Internal Affairs are suspending the provision of certain services related to vehicles, including the disposal of vehicles. 

Later, the Deputy Prime Minister for European and Euro-Atlantic Integration and Minister of Justice of Ukraine, Olha Stefanishyna, stated that there has been the most extensive external cyber attack on the state registers of Ukraine in recent times. 

In a comment to Glavkom, the Deputy Director of the analytical system YouControl for legal matters, Danylo Globa, noted that this situation negatively affects the operation of many state and non-state systems that use data from the registers.

Earlier, the Ministry of Justice predicted the recovery timelines for state registers after the cyber attack.
