The recent cyber attack on US government agencies, according to the cyber security company, affected about 50 organizations. As many as 18,000 organizations had malware code in their systems and the aforementioned 50 suffered major violations. The US Treasury and departments of homeland security, state and defence are known to have been targeted.
It has already been seen in the media that Mike Pompeo has accused Russia of the attack. Mr Pompeo said on Friday: "We can say pretty clearly that it was the Russians that engaged in this activity."
He said that Russia was trying to "undermine our way of life", and that Russian President Vladimir Putin "remains a real risk".
So too have the chairs of the Senate and House of Representatives' intelligence committees.
The Republican Chair of the Senate intelligence committee, Marco Rubio, tweeted that it is "increasingly clear that Russian intelligence conducted the gravest cyber intrusion in our history". He said the response "must be proportional but significant".
However, Trump likes the idea that the Chinese are responsible and behind the attack.
Hacking the heart of the US government Mr Mandia told CBS News that the cyber attack "was very consistent" with what US officials know about the work of Russia's foreign intelligence agency, the SVR.
"I think these are folks that we've responded to in the '90s, in the early 2000s. It's a continuing game in cyberspace," he said.
The Russians have denied "unfoundedness of the claim" but many US intelligence agents hold the Russian government responsible for the attack.
And some of the Democrats have no doubt at all that the attack was carried out by the Russians. Such as Adam Schiff, Democrat chair of the House intelligence committee: "I don't think there's any question that it was Russia".
In short, the attack was without enormous destructive intentions, only the theft of sensitive and confidential data. Hackers managed to gain access to major organisations by compromising network management software developed by the Texas-based IT company SolarWinds. It is thought they targeted a narrow number of organisations in an attempt to steal national security, defence and other related information.
