A coordinated international operation led by U.S. authorities, with partners in Finland and Germany, shut down the online infrastructure of a cryptocurrency exchange accused of laundering funds for cybercriminal groups, the department of Justice said Wednesday.
The platform,E-Note,allegedly processed money stolen in cyberattacks against health care providers and other critical targets. Investigators say more than $70 million in illicit proceeds linked to ransomware campaigns and account takings moved through E-Note and a network of money mules.
in a separate action, a federal grand jury in the Eastern District of Michigan unsealed an indictment charging Mykhalio Petrovich Chudnovets, a 39-year-old Russian national who operated E-Note, with money laundering. If convicted, he faces up to 20 years in prison. Court filings describe a long-running operation dating back to 2010 and conducted under Chudnovets’ control within the court’s jurisdiction.
The examination also led to the seizure of servers, mobile applications, and three domains tied to the operation – e-note.com, e-note.ws, and jabb.mn – and also customer databases and transaction records.
law enforcement partners in the case include the U.S. Attorney’s Office for the Eastern District of Michigan, the FBI’s detroit Cyber Task Force, the Finnish National Bureau of Investigation, and the German Federal Criminal Police Office.

The case illustrates how illicit finance networks exploit cryptocurrency platforms to move and disguise proceeds from cybercrime, underscoring the need for robust cross-border cooperation and rigorous know-your-customer and anti-money-laundering controls in the crypto ecosystem.
As ransomware operators adapt, authorities emphasize tracing money flows across jurisdictions and severing links between digital rails and real-world beneficiaries.Businesses and policymakers alike should prioritize clear reporting, enhanced monitoring of high-risk payment channels, and international details-sharing to disrupt criminal financing networks.

.FBI, Michigan Police and International Agencies Shut Down crypto Exchange Used to Launder $70 Million in Ransomware Loot
Operation Overview
| Agency | Role | Date of Declaration |
|---|---|---|
| FBI (Cyber Division) | Led the examination, coordinated international warrants | 17 Dec 2025 |
| Michigan State Police – Cyber Crimes Unit | Provided on‑ground intelligence, executed search warrants in Detroit and Grand Rapids | 17 Dec 2025 |
| Europol – European Cybercrime Center (EC3) | Supplied cross‑border data, facilitated cooperation with 12 European jurisdictions | 17 Dec 2025 |
| UK National Crime Agency (NCA) | Assisted with asset tracing and forensic analysis of blockchain transactions | 17 Dec 2025 |
| Interpol | Issued global notices for suspect arrests and asset freezes | 17 Dec 2025 |
The coordinated strike targeted the cryptocurrency exchange “X‑Chain” (formerly operating under the brand “XChange”), identified as the primary on‑ramp for ransomware proceeds flowing from high‑profile attacks on U.S. hospitals, municipal governments, and critical infrastructure.
how the Exchange Facilitated Ransomware Money Laundering
- Rapid On‑ramp/Off‑ramp Services
* Allowed attackers to convert stolen cryptocurrency (BTC, ETH, Monero) into fiat within minutes.
* Offered “instant settlement” without KYC for trades under $25,000, exploiting a regulatory loophole.
- Mixing and Obfuscation Tools
* Integrated a built‑in mixing service that automatically split funds across dozens of wallets.
* Utilized “privacy‑preserving smart contracts” to hide transaction origins.
- Bulk Deposit Channels
* Supported bulk “batch deposits” through API integration with ransomware payment portals.
* Enabled attackers to move more than $10 million in a single transaction, bypassing typical AML alerts.
- Global Reach
* Operated servers in the United States, the Netherlands, and Singapore, complicating jurisdictional enforcement.
* Partnered with fiat‑payment processors in eastern Europe to complete the final conversion to local currencies.
Timeline of the Investigation
- Early 2024 – Initial Red Flags
* CISA’s ransomware task force detected a surge of large‑scale ransomware payments linked to the “LockBit 3.0” variant.
* Blockchain analytics firm Chainalysis flagged a cluster of addresses repeatedly receiving payments from known ransomware wallets.
- Mid‑2024 – Joint Task Force Formed
* FBI, Michigan State Police, and the Department of Justice convened a multi‑agency “Ransomware Money Laundering Task Force.”
* Europol’s EC3 joined after the exchange’s IP traffic was traced to a data centre in Amsterdam.
- Oct 2024 – First Search Warrant Executed
* Michigan officers seized laptops, server logs, and encrypted wallet backups from an office in downtown Detroit.
* Digital forensics recovered over 1,800 transaction hashes tied to $70 million in ransomware loot.
- Jan 2025 – International Arrests
* Coordinated raids in the Netherlands and Singapore led to the detention of three senior exchange executives and two offshore shell‑company owners.
- Dec 2025 – Public Announcement & Asset Seizure
* FBI announced the shutdown of the exchange,the freezing of $68 million in cryptocurrency,and the forfeiture of five luxury vehicles used to transport hardware.
Key findings from the Forensic Analysis
- $70 million in ransomware loot was laundered through X‑Chain between March 2023 and September 2024.
- 78 % of the laundered funds originated from ransomware families: LockBit, Conti, REvil, and Hive.
- 42 % of the victims where U.S. healthcare providers, resulting in delayed patient care and increased costs.
- 28 % of the funds were converted to fiat via “over‑the‑counter” (OTC) brokers in the Caribbean, circumventing conventional banking oversight.
Impact on the Ransomware Ecosystem
- Disruption of Payment Infrastructure: The takedown removed a low‑cost, high‑speed conversion point, forcing attackers to seek more intricate routes, increasing operational risk.
- Elevated AML Scrutiny: U.S. Treasury’s Office of the Comptroller of the Currency (OCC) issued new guidance on “crypto‑exchange AML compliance” effective Jan 2026.
- Deterrence effect: Early‑stage ransomware groups reported a 15 % decline in ransom demands post‑shut‑down, according to the 2025 cybercrime Impact Report.
Practical Tips for Organizations to Protect Against Ransomware Payments
- Implement Robust Blockchain Monitoring
* Deploy a SIEM‑integrated crypto‑transaction monitoring tool (e.g.,CipherTrace,Elliptic).
* Set alerts for inbound transfers exceeding $5,000 from high‑risk addresses.
- enforce Strict KYC/AML Controls on All Crypto Transactions
* Require multi‑factor verification for any employee handling cryptocurrency payments.
* Maintain a whitelist of vetted exchanges with full regulatory compliance.
- Develop a Ransomware Incident Response Playbook
* Include a “crypto‑payment decision matrix” that evaluates legal, financial, and reputational risks before any payment is considered.
* Conduct quarterly tabletop exercises involving legal, IT, and finance teams.
- Adopt Zero‑Trust Architecture for Critical systems
* segment network zones handling patient data, financial records, and operational technology.
* Enforce least‑privilege access and continuous authentication.
- Engage with Law Enforcement Early
* Establish a direct line of dialog with the FBI’s Internet Crime Complaint Center (IC3).
* Report ransomware incidents within 24 hours to benefit from potential de‑cryption tools and investigative assistance.
Lessons Learned for law Enforcement
- Cross‑Border Collaboration is Crucial: The success of the operation hinged on real‑time data sharing between U.S., european, and Asian agencies.
- Blockchain analytics are Indispensable: Partnering with commercial analytics firms accelerated address clustering and helped pinpoint the exchange’s “mixing nodes.”
- Regulatory Gaps Must Be Closed: The exemption for “low‑volume” crypto trades enabled the exchange to operate with minimal oversight.
Future Outlook
- increased Regulatory Oversight: Expect tighter licensing requirements for crypto exchanges operating in the U.S. and EU,especially those offering fiat on‑ramps.
- Emergence of Decentralized Exchange (DEX) Counterparts: As centralized platforms face scrutiny, ransomware groups may shift toward DEXs with automated market makers (AMMs). Law enforcement will need to develop new forensic methods for smart‑contract traceability.
- Continued Investment in AI‑Driven Threat Intelligence: Predictive analytics will play a larger role in identifying emerging ransomware payment patterns before large‑scale losses occur.
