The United States Treasury Department on Monday notified Congress that a China-backed group hacked workstations in the department earlier this month.
The alleged incident occurred on Dec. 8, when a Chinese-backed agent used a stolen key to remotely access workstations and unclassified documents, according to CNN.
“Based on available indicators, the incident has been attributed to a Chinese state-sponsored Advanced Persistent Threat (APT) actor,” Aditi Hardikar, assistant secretary for management at the US Treasury, wrote in the letter.
A department spokesperson said the stations that were impacted have been taken offline and officials are working with federal law enforcement to investigate the incident.
It is not clear how many workstations were impacted, or what documents were accessed.
“There is no evidence indicating the threat actor has continued access to Treasury systems or information,” the Treasury spokesperson told the outlet.
