9 federal agencies and about 100 companies hit by SolarWinds hack: The White House

Nine federal agencies and about 100 private sector companies were compromised as a result of the SolarWinds hack, the White House has said.

Although the hack was “likely of Russian origin,” the hackers launched their attack from inside the US, Anne Neuberger, Deputy National Security Advisor for Cyber and Emerging Technology, said in a briefing on Wednesday.

To carry out the attack, hackers installed a malware in the Orion software sold by the IT management company SolarWinds.
