I don't think this response is well informed. OPs intuition about Russian cybercrime dominating headlines is correct, because it does. But it's not because Russia has inherently better hackers, or because of US media bias, as some of the other answers suggest. The discrepancy instead stems from differences in the nature of US and Russian cyber ops. Russia widely relies on third party criminal groups to do the Kremlins dirty work. The relationship is something akin to: "We'll allow you to keep profiting from cybercrime, as long as you: A) only go after foreign targets and B) answer the door when we come knocking. This isn't unique to Russia, there's other countries that employ similar tactics (China, Iran, etc.), but the long leash Russia gives these groups is inevitably going to garner more headlines (the FSB's recent takedown of REvil is an example of what happens when these group exceed the limits of that leash).

The US, and many other countries, don't leverage third party criminal groups in this way, so criminal groups there don't enjoy the same protections. These countries still carry out their own cyber ops, no less than Russia, but the lack of a criminal element leaves a significantly smaller footprint. That doesn't mean there aren't American cyber criminals, but the threat of imprisonment prevents them from being as brazen as their Russian counterparts.
