E-Note

E-Note was a Cryptocurrency exchange and payment processor seized by the FBI, Michigan State Police, German Federal Criminal Police (BKA) and Finnish National Bureau of Investigation as a laundering infrastructure for more than $70 million in ransomware and account-takeover proceeds. Russian national Mykhalio Petrovich Chudnovets was charged with conspiracy to launder proceeds through the exchange since 2017.

E-Note operated as a conversion service for ransomware groups, enabling proceeds to move from Cryptocurrency into fiat or other digital assets while obscuring the trail. Its operational model — minimal KYC requirements and ready accessibility — made it an attractive laundering rail for ransomware operators seeking to monetise quickly. The nine-year operational window before seizure illustrates both the patience required for multi-jurisdiction investigations and the difficulty of seizing infrastructure with international hosting. The exchange's removal closes a durable exit route that criminal groups had relied on across multiple ransomware campaigns.

For the ransomware ecosystem, E-Note's seizure removes a major laundering rail and produces intelligence exposure that outlasts the infrastructure itself. For law enforcement, the multi-jurisdiction model (FBI-led, EU partners executing domestic warrants simultaneously) is the same operational template applied to BTC-e, Hydra, and subsequent enforcement actions. The Chudnovets indictment follows the pattern of naming the exchange operator as the choke point rather than pursuing individual ransomware affiliates.
