Hackers suspected to be working for the Russian government have been monitoring emails at the U.S. Treasury Department and a U.S. agency responsible for deciding policy around the internet and telecommunications, Reuters reported, citing people familiar with the matter.
“The United States government is aware of these reports and we are taking all necessary steps to identify and remedy any possible issues related to this situation,” John Ullyot, a spokesman for the National Security Council, said in a statement.
Two key House lawmakers are seeking answers from the Internal Revenue Service (IRS) about whether any of the agency's systems were compromised as part of a massive cyberattack.
"We believe that it is important to provide taxpayers with a full understanding of the extent of the SolarWinds Orion compromise to maintain confidence in the federal tax system," Reps. Bill Pascrell (D-N.J.) and Mike Kelly (R-Pa.) — the chairman and ranking member, respectively, of the House Ways and Means Committee's oversight subcommittee — wrote in a letter Friday to IRS Commissioner Charles Rettig.
The letters from Pascrell and Kelly come after the leaders of the Senate Finance Committee on Thursday pressed the IRS for a briefing about whether any taxpayer information was compromised in the SolarWinds hack.
