The FBI and the Department of Homeland Security determined in a report released Thursday that Russian state actors were behind computer hacks this year that exposed some of the Democratic National Committee's secrets.

America's intelligence community, the report reveals, code-named the effort 'Grizzly Steppe,' and referred to specific hackers or groups of hackers by pet names including 'CosmicDuke,' 'COZYBEAR,' 'CrouchingYeti,' 'Energetic Bear,' 'Fancy Bear,' 'OnionDuke,' 'Sandworm,' 'SOURFACE' and 'Tiny Baron.'

The report was released as the Obama administration and Moscow traded barbs over a raft of new White House sanctions against Russian government actors the White House says are tied to election-year computer hacking in the U.S.

President-elect Donald Trump said in a statement late Thursday that '[i]t's time for our country to move on to bigger and better things.'

'Nevertheless, in the interest of our country and its great people, I will meet with leaders of the intelligence community next week in order to be updated on the facts of this situation.'

President Barack Obama's intelligence agencies released a report Thursday that seemed to back his decision to level new sanctions against Russia, while President-elect Donald Trump called for America to 'move on to bigger and better things'

The FBI and Homeland Security Department nicknamed the Russian cyber attack operation as 'Grizzly Steppe,' and illustrated its techniques in a report issued Thursday

Groups of hackers that the FBI and DHS refer to as 'APT28' and 'APT29,' they said, infiltrated the Democratic National Committee for more than a year, and didn't stop until after the November 8 presidential election

Evidence is strong, the FBI and DHS concluded, tying Russia to the DNC hack, which unmasked an intra-party plot to promote Hillary Clinton's primary candidacy while marginalizing her main opponent, Sen. Bernie Sanders.

The report makes no reference, however, to the more explosive leaks of emails hacked from the personal account of Clinton campaign chairman John Podesta.

The 13-page document's main purpose is to educate government and political IT professionals about how to protect their computer systems from future cyber attacks.

But its most volatile statements concern intelligence findings that establish the involvement of Russian military and civilian intelligence agencies in past hacking.

Those services found ways to 'compromise and exploit networks and endpoints associated with the U.S. election, as well as a range of U.S. Government, political, and private sector entities,' Thursday's report concludes.

Mockery: This was how Russia's embassy in London responded to the new sanctions from the Obama administraitoin on Thursday, mocking the outgoing president as a 'lame duck'

The two agencies had already released a statement in October attributing the attacks to Russia, claiming they were an attempt to 'interfere' with America's presidential election.

The new report does not expand on that specific allegation or provide new evidence to support it.

The two main Russian entities identified on Thursday include a hacking group known as APT29, tied to Russia's Federal Security Service – the FSB, one of sevreal successor agencies to the infamous KGB which Russian President Vladimir Putin once led.

That group is thought to have infiltrated the DBC's computers for more than a year, pulling out documents regularly.

The FBI and DHS tied another group of hackers, known as APT28, to Russia's military intelligence service, known as the GRU.

Some security experts have written that APT28 was the entity behind the hack of Podesta's emails, but Thursday's report is silent on that claim.

APT28, The Hill reported Thursday, is thought to be the responsible for providing stolen files and emails from both hacking operations to WikiLeaks, which published them online.

The attackers, the two U.S. intelligence agencies reported, executed 'spearphishing' operations that lured computer users to click on links inside emails which led to malicious addresses.

Some of those online destinations fed malware into the victims' computers, which then allowed the code to migrate into the DNC's servers, providing the hackers with long-term access.

The result, the FBI and DHS concluded, was 'the exfiltration of information from multiple senior party members.'

'The U.S. Government assesses that information was leaked to the press and publicly disclosed,' the report declares.
