In 2016 Arizona and Illinois caught attempts to breach their voter registration systems etc. The attacks were traced back to "King Servers" who is owned by Vladimir Fomenko a 26 year old in Siberia. "King Servers" contracted its servers through a Dutch ISP owned by Pavel Vrublevsky.
Pavel Vrublevsky accuses Sergei Mikhailov of fabricating the evidence that got him 2.5 years in Russian prison And many have long felt that Pavel was likely an Agent for the FSB at that point and had a show trial which seems more likely as he was let out of prison almost right away instead of serving time.
It's also possible that in Russia when you lead such an operation you have a responsibility to make sure nothing leaks. Doesn't mean he leaked it, but if anyone did then he becomes responsible and they charge him. Who knows really.
