The US Cybersecurity and Infrastructure Security Agency (CISA) has announced that it has found no indication of any other federal agency being hacked in the recent cyberattack on the US Treasury Department, which was attributed to China government-backed hackers.

The Treasury Department confirmed the breach on December 30, revealing that the hackers had gained remote access to employee workstations and unclassified documents. The hackers reportedly obtained a private key from one of the department's technology vendors, BeyondTrust, which is used for remote technical support. However, it remains unclear how the key was stolen.

According to a letter sent to senior US lawmakers, the hackers specifically targeted the Treasury's global sanctions office. The Washington Post reported last week that the hackers were focused on this particular office, raising concerns about the potential motivations behind the attack.

The Chinese government has denied any involvement in the hacking incident, with a spokesperson in Washington D.C. issuing a statement to that effect. However, the US government has been adamant that the attack was carried out by China-backed hackers.

CISA's statement on Monday emphasized that the agency is continuing to monitor the situation and coordinate with relevant federal authorities to ensure a comprehensive response to the cyberattack. This development comes as the US government grapples with the implications of the breach and works to prevent similar incidents in the future.

The incident highlights the ongoing threat of cyberattacks to US government agencies and the need for robust cybersecurity measures to protect against these types of threats. As the US government continues to investigate the breach, it remains to be seen what measures will be taken to prevent similar incidents in the future.

The Treasury Department's breach is just the latest in a series of high-profile cyberattacks on US government agencies in recent years. The incident serves as a reminder of the importance of cybersecurity in protecting sensitive government information and preventing unauthorized access to critical systems.

As the situation continues to unfold, it is likely that more information will come to light about the nature of the attack and the steps being taken to prevent similar incidents in the future. For now, CISA's statement provides some reassurance that the breach was contained and did not spread to other federal agencies.
