Who really did the hack?

[Swordsmyth]

British and U.S. intelligence agencies say Russian hackers hijacked Iran-based cyberspy groups to attack dozens of countries and organizations while pretending to be Iranian.
The details of the operation were revealed (https://www.ncsc.gov.uk/news/turla-group-behind-cyber-attack) in an October 21 statement accompanying a joint advisory (https://www.ncsc.gov.uk/news/turla-group-exploits-iran-apt-to-expand-coverage-of-victims) by Britain’s National Cyber Security Center (NCSC) and the U.S. National Security Agency (NSA).

We know the CIA can forge clues to make it look like anybody they want is guilty, why should we believe that it was the Russians?

If I were to take a guess, I'd say it was the US that was responsible for the hacking.

I'd say the British 1st and the US as the 2nd guess.
