There was recently this german lady reporter who posed as actively pro-Putin for few months and it didn't take long for fsb/gru to come to her online.

It started small, just check this or that, little favor there but soon escalated to proper spycraft. Some other folks reported having death threats against family. Its for peanuts, few hundred euros mostly. They just need to find the dumbest and most desperate folks to commit acts of treason.

The chances of this being real are basically zero, or Russia would be getting double agented, and reverse intelling themselves, out the arse. Instead all we get are attempts to connect random events, of which there are endless viable suspects, to Russia.

It's fair to say that if one jumps in the middle of a fight, they should expect to get punched, but it's also fair to say that for now Russia has been avoiding throwing much in the way of punches.
