Until you hear them coming from an American. Probably the most prolific country involved in state sponsored cyber-crime.
When we hear about Russians or North Koreans its generally crap information given out to obfuscate our screw ups.
Some good examples include the NHS blaming North Korea for "CYBER ATTACKS!!" instead of owning up to having spent the budget for upgrading from XP to a proper OS or the Americans claiming that Russia hacked their elections rather than just owning up to having been bank rolled by them.
The US have become so blaze in their utter disregard to the rest of the worlds IT infrastructure that they have even allowed their hacking tool-kits to escape too the wild, allowing criminals access to tools more powerful than ever before. (though I believe a eastern European criminal hacker would still be the more trustworthy user of these tools than the Americans...)
