The Chinese government likely hacked computers at the Federal Deposit Insurance Corporation in 2010, 2011 and 2013, according to a US congressional report that cites an internal investigation by the banking regulator.
"Even the former Chairwoman's computer had been hacked by a foreign government, likely the Chinese," staff at the US House of Representatives Committee on Science, Space and Technology said in the report released on Wednesday.
The Chinese Embassy in Washington did not have immediate comment on the allegations.
China has long been a prolific hacking adversary for the United States, although intelligence officials believe Beijing has decreased its hacking activity since signing a pledge with Washington last September to refrain from breaking into computer systems for the purposes of commercial espionage.
The congressional report provided the latest example of how deeply Beijing has penetrated US government computers.
