Global Collaboration Takes Center Stage in Cybercrime Prosecution

Vancouver, Canada — The Federal Bureau of Investigation has increased its reliance on coordinated international investigations, announcing a series of joint cybercrime cases with foreign law enforcement agencies in Europe, Asia, and Latin America. The FBI’s cyber division has positioned this expansion as a necessary evolution in combating transnational threats that operate beyond the jurisdiction of any single nation. By leveraging mutual legal assistance treaties and bilateral data sharing agreements, the agency is not only speeding up the acquisition of critical evidence but also ensuring prosecutions are better informed and supported by admissible proof from multiple jurisdictions.

Amicus International Consulting has reviewed these developments and released an updated guidance framework for clients on the basics of Mutual Legal Assistance Treaties, often referred to as MLATs, and cross-border data requests. For companies, individuals, and legal practitioners navigating multi-jurisdictional investigations, understanding these processes has become essential to managing both legal compliance and operational risk.

The Rise of Joint Cyber Investigations

In recent years, cybercrime has shifted from isolated incidents to complex networks involving actors in multiple countries. These networks may include malware developers in one jurisdiction, hosting providers in another, and financial mule networks spanning several continents. This decentralization allows criminals to exploit jurisdictional boundaries, making unilateral law enforcement action insufficient.

The FBI cyber unit has been developing operational partnerships with agencies such as Europol’s European Cybercrime Centre, the UK’s National Crime Agency, Japan’s National Police Agency, and Brazil’s Federal Police. These relationships are structured to allow for rapid intelligence sharing, coordinated arrests, and synchronized search warrant execution.

Case Study: Coordinated Takedown of a Ransomware Operation

In 2023, a joint investigation between the FBI, Europol, and the Dutch National Police led to the dismantling of a ransomware group responsible for attacks against hospitals, municipal governments, and corporate entities. The operation involved simultaneous raids in three countries, seizure of servers, and arrests of key actors. The success was dependent on an MLAT request from the U.S. to the Netherlands, which provided the legal authority to seize and transfer evidence in compliance with both nations’ legal standards.

Understanding MLATs and Their Function

A Mutual Legal Assistance Treaty is a formal agreement between countries to exchange information and evidence for use in criminal investigations and prosecutions. MLATs are not informal data-sharing channels; they are legally binding frameworks that require requests to meet specific evidentiary and procedural criteria.

In the United States, the Office of International Affairs within the Department of Justice acts as the central authority for incoming and outgoing MLAT requests. Each request must be tailored to the requirements of the treaty partner, which can vary significantly. Typical requirements include sworn statements, case background summaries, detailed lists of evidence sought, and assurances regarding the use and protection of the information.

MLAT Request Workflow

The general process for an outgoing MLAT request from the United States includes:

  1. Drafting the request with input from prosecutors and investigators.

  2. Submit it through the Office of International Affairs.

  3. Review by the treaty partner’s central authority.

  4. Judicial or administrative approval in the treaty partner’s jurisdiction.

  5. Execution of the request by local law enforcement.

  6. Transmission of the collected evidence back to the United States through secure legal channels.

Case Study: Delayed Evidence Due to Procedural Errors

A 2022 cyber fraud case involving servers in Eastern Europe was delayed by more than six months because the initial MLAT request lacked certain authentication documents required under that country’s procedural code. The FBI had to revise and resubmit the request, losing valuable time during the investigation. This incident reinforced the importance of precise compliance with treaty-specific formalities.

Cross-Border Data Requests Beyond MLATs

While MLATs are the gold standard for admissible evidence, they can be time-consuming. For urgent cybercrime cases, agencies may also rely on mechanisms such as the Budapest Convention on Cybercrime, which facilitates expedited preservation of electronic evidence pending a formal request. Direct company-to-government requests, executed under domestic law in the host country, can also provide faster access. However, the resulting information may require additional legal steps before it can be used in court.

Amicus Guidance on Data Request Compliance

Amicus International Consulting advises companies and individuals who may receive foreign data requests to take the following steps:

  • Verify the Legal Authority: Ensure the request comes from a recognized central authority under a valid MLAT or other lawful instrument.

  • Review Scope and Specificity: Vague or overly broad requests may need clarification or narrowing to meet legal requirements.

  • Protect Privacy and Confidentiality: Comply with applicable privacy laws, including the General Data Protection Regulation in the EU, when transferring personal data.

  • Maintain Chain of Custody: Document every step of the data collection and transfer process to ensure admissibility in court.

Case Study: Company Response to a Foreign Data Request

In 2021, a U.S.-based cloud storage provider received a request from a European law enforcement agency seeking records related to a cyber extortion case. Amicus advised the company to confirm whether the request was backed by an MLAT submission through the U.S. Department of Justice. Upon confirmation, the company provided the records in a format that preserved metadata integrity, which later proved critical in securing a conviction abroad.

Benefits and Challenges of International Cooperation

International cooperation can yield significant benefits in cybercrime cases, including faster identification of suspects, recovery of stolen assets, and coordinated disruption of criminal infrastructure. However, it also introduces challenges such as:

  • Differing evidentiary standards between jurisdictions.

  • Delays due to translation and certification requirements.

  • Conflicts between privacy laws and law enforcement demands.

  • Political sensitivities are heightened when cases involve high-profile targets.

Case Study: Privacy Law Conflict in Data Sharing

A multinational phishing investigation in 2020 faced obstacles when one participating country’s privacy regulator questioned the legality of transferring specific user data to U.S. authorities. The issue was resolved through a modified MLAT request that excluded sensitive identifiers, but the delay allowed some suspects to alter their online infrastructure.

Amicus Recommendations for Clients in Cross-Border Cyber Cases

Amicus International Consulting recommends proactive preparation for organizations that operate across borders or host data from multiple jurisdictions:

  1. Map Data Locations: Maintain an up-to-date inventory of where company data is stored and under which legal regimes.

  2. Designate a Response Team: Identify internal legal and technical staff who can quickly handle lawful data requests.

  3. Engage with Counsel Early: Retain legal advisors familiar with MLAT and cross-border data laws before receiving a request.

  4. Develop Internal Protocols: Ensure standardized procedures for logging, authenticating, and transferring data in compliance with legal requirements.

Looking Ahead: The Future of MLAT Efficiency

The U.S. and several treaty partners are exploring reforms to make MLAT processes more efficient. Proposed changes include standardized electronic submission formats, expanded use of secure online evidence portals, and dedicated liaisons in partner countries to expedite urgent requests. While these changes are still in development, early pilot programs suggest they can reduce request processing times from months to weeks.

Conclusion

The FBI’s push for more joint cybercrime cases with foreign partners reflects a recognition that no single nation can unilaterally address the evolving complexity of transnational digital crime. Mutual Legal Assistance Treaties and related data-sharing agreements are central to these efforts, but they require precision, compliance, and strategic planning to be effective.

Amicus International Consulting’s updated MLAT and data request guidance provides clients with practical tools to navigate these high-stakes scenarios, ensuring both legal compliance and operational security. For those involved in cross-border investigations, understanding these processes is no longer optional — it is a necessary safeguard against missteps that could compromise an entire case.
