From the sounds of it CHS1 is probably a Russian national. I'm honestly surprised s/he hasn't asked for compensation or a visa; although we don't know who they are the ransomware group certainly does and I would be scared they are plotting revenge (especially if they end up having to leave the US). If I were the FBI I would be putting this dude in witness protection and building them a new identity.
