The latest US security breach attributed to systematic attempts by China to compromise US institutions and critical infrastructure has impacted the US Treasury. The intrusion is being billed as “a major cybersecurity incident”.

According to a letter from the US Department of the Treasury: “The threat actor was able to override the service’s security, remotely access certain Treasury Departmental Office user workstations, and access certain unclassified documents maintained by those users… Based on available indicators, the incident has been attributed to a China state-sponsored Advanced Persistent Threat (APT) actor.”
