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 — a readily accessible exchange with minimal KYC requirements — made it an attractive laundering rail for ransomware operators seeking to monetise their proceeds efficiently. The exchange's nine-year operational window before seizure illustrates both the patience of multi-jurisdiction investigations and the difficulty of seizing infrastructure with international hosting.

For the ransomware ecosystem, E-Note's seizure removes a Major laundering rail that had served criminal groups for nearly a decade. For law enforcement, the multi-jurisdiction cooperation model (FBI-led, with EU partners executing domestic warrants simultaneously) is the operational template that has been applied to exchanges including BTC-e, Hydra and now E-Note.
