The Russians would likely try to exploit such an e-mail to gain something more tangible or if their goal was to make the FBI look inept they would send the message to a much wider audience.
Not the OP, but, well, just as it could've been Russians, it could be North Koreans, Chinese, or anyone else. As a Russian, the comment just seemed unnecessary, though I'm obviously biased.
>Do you honestly not believe that Russia enlists hackers to poke at the seams in the US?
No, but I believe you should have some evidence before you start accusing them. Otherwise it is very much the "blame Russia" type comment that poster was mocking.
It's not xenophobia when their legal system incentivizes hacking foreigners and hacks just happen to keep popping up from Russia. Nor is pointing out blatantly obvious trends "left".
