Email accounts used by the top management of the Ministry of Finance have been compromised by suspected hackers of the Russian governmentagainst several US federal agencies, said Oregon Senator Ron Wyden. The senior Democrat on the Senate Finance Committee said the “full depth” of the treasury hack was “not known.”
The Senate Finance Committee staff were informed of a serious breach of the Treasury Department under the Treasury DepartmentWyden said in a statement Monday night.
“Hackers have broken into Treasury Department systems, which are the highest officials in the department. The Treasury Department still doesn’t know all of the actions hacked on or exactly what information was stolen,” said Wyden.
The Internal Revenue Service said there was no evidence that the agency was compromised or that taxpayer data was affected, Wyden added.
According to Wyden, Microsoft made the department aware of the compromise, which began in July.
Cyber security experts believe that a sophisticated group of hackers was able to break into US government networks earlier this year through a hole in SolarWinds-developed products that provide software for government agencies and large corporations.
The hackers were then able to access confidential information and communications from SolarWinds customers, including the treasury, trade and energy departments and Los Alamos National Laboratory, which monitors the country’s nuclear weapons.
President Trump launched the cyber espionage campaign, suggesting that China may be the culprit, but senior US officials including Secretary of State Mike Pompeo and Attorney General William Barr have pointed fingers at Russia.
“This has been a very significant effort and I think it is the case that we can now say fairly clearly that it was the Russians who took part in this activity,” said PompeoFriday in an interview on the conservative radio show “The Mark Levin Show”.
During a press conference on Monday, he said that “it certainly seems to be the Russians”.
The Kremlin has denied responsibility.
