This is kind of like referring to Joe Biden as a Delaware lawyer.

Andrey is famous for operating unicc, not infraud.

I found the US-Russia cooperation here intriguing given the contentious discussions over the impending invasion of Ukraine. Would anyone with more knowledge of geopolitics care to shed some light on that?

This is Russia showing that being on good terms with it is useful for the US. It has the power to stop the ransomware problem if it wants to.

The implication being that if the US does too much about Ukraine (meaningful weaponry/sanctions) there won't be cooperation - but that if they do the bare minimum, well, their law enforcement might start mysteriously catching more people.

I wonder if what we perceive as global theater is actually just leveraging concessions in the background, a weird parallel to "informants" being whisked away as if they've exceeded their operational life cycle or purpose; a pazzi.

Besides geopolitics, simple answer could be that FSB protector who covered this guy finally realized that crypto goes down for long time, so it is better to take all collected funds now.

Nation states are big and relations between them are absurdly complex. You don't put all collaboration on hold every time a territorial scuffle is happening, especially when nothing explicit has actually happened yet. Just "tension".

I'm speculating here but It's possible Putin changed his mind and now wants his share of their money which often counts to millions of dollars.
