He said, “I can’t say too much because we’re still right about what this is, and I’m sure some of it will remain classified.”
Now at least half a dozen federal agencies are targeted, including the cyber branch of Homeland Security and the Department of Agriculture, Commerce, Energy and the State. Investigators are still trying to determine if, if any, government data hacks could be accessed or stolen.
Pompeo said, “Suffice it to say that the US government was a significant attempt to use a piece of third-party software to essentially embed code inside the systems and it is now available to private companies and worldwide Appears as systems of companies and governments, ”Pompeo said.
The White House said on Friday that Trump is being brief and “working very hard” to deal with the hack.
When asked about Trump’s silence on the matter, Pompeo said that work was going on behind the scenes.
“There are many things you like to say, ‘Boy, I’m going to call him out, but a sensible course of action to protect the American people is to go about your business in peace and protect freedom, ” he said.
The Russian embassy in Washington has denied involvement in the hack.
But Moscow has been linked to several recent violations, including hacking of Democratic officials during the 2016 US presidential election.
CNN previously reported that behind the attack on Firete was a Russian-affiliated group known as APT29.
That same evening, FireEye identified its own intrusion source as malware hidden in its software updates published by software vendor SolarWinds, which is used by many federal civilian agencies for network management.
Malware updates were sent to 18,000 SolarWind customers, including US government agencies and Fortune 500 companies.
