As part of today’s blockbuster prisoner swap between the US and Russia, which freed the journalist Evan Gershkovich and several Russian opposition figures, Russia received in return a motley collection of serious criminals, including an assassin who had executed an enemy of the Russian state in the middle of Berlin.

But the Russians also got two hackers, Vladislav Klyushin and Roman Seleznev, each of whom had been convicted of major financial crimes in the US. The US government said that Klyushin “stands convicted of the most significant hacking and trading scheme in American history, and one of the largest insider trading schemes ever prosecuted.” As for Seleznev, federal prosecutors said that he has “harmed more victims and caused more financial loss than perhaps any other defendant that has appeared before the court.”

What sort of hacker do you have to be to attract the interest of the Russian state in prisoner swaps like these? Clearly, it helps to have hacked widely and caused major damage to Russia’s enemies. By bringing these two men home, Russian leadership is sending a clear message to domestic hackers: We’ve got your back.
