Email accounts were hacked at the US Treasury Department

Dozens of email accounts at the US Treasury Department were compromised by the powerful hackers responsible for a wide-ranging espionage campaign against US government agencies, the office of US Senator Ron Wyden said on Monday.

In a written statement, Wyden’s office said that Senate Finance Committee staff were briefed that the hack of the Treasury Department appears to have been a significant one, “the full depth of which isn’t known.”

Wyden, the most senior Democrat on the committee, said that Microsoft notified the agency that dozens of email accounts had been compromised and that the hackers also penetrated the systems at Treasury’s Departmental Offices division, which is home to its top officials.
