U.S. Treasury thwarted hack by Russians

U.S. Treasury thwarted hack by Russians The U.S. Treasury last month repelled cyber attacks by a pro-Russian hacker group, preventing disruption and confirming the effectiveness of the department’s stronger approach to financial system cybersecurity, a U.S. Treasury official said on Tuesday.

The Treasury has attributed the distributed denial of service (DDoS) attacks to Killnet, the Russian hacker group that claimed responsibility for disrupting the websites of several U.S. states and airports in October, said Todd Conklin, cybersecurity counselor to Deputy Treasury Secretary Wally Adeyemo.

The incident, not previously reported, occurred a couple of days before similar attacks from Killnet on U.S. financial services firms, Conklin told a financial services industry and regulator conference on cybersecurity.

Conklin described the attack on the Treasury as “pretty low-level DDoS activity targeting Treasury’s critical infrastructure nodes.” Adeyemo told the conference the incident was a “stark reminder” that Treasury and financial services firms face the same threats, especially since Russia launched its war on Ukraine in February.
