US government agencies hit by cyberattack, official says

U.S. government networks were hit by a cyberattack affecting several federal agencies, Cybersecurity and Infrastructure Security Agency Director Jen Easterly confirmed on Thursday.

CISA, a part of the Department of Homeland Security, previously identified a gap in software security believed to have been exploited in attack.

An electronic file transfer application, MOVEit Transfer, is thought to be the target of the broader cyber intrusion, one official said.

A spokesperson for Mandiant, the cyber intelligence arm of Google Cloud, said government data was stolen in the attack. CISA officials declined to say how many federal agencies were impacted and did not say who was behind the attack.
