The U.S. Embassy in Australia and the Federal Bureau of Investigation (FBI) have announced the completion of a joint operation with the Australian Federal Police (AFP) that dismantled an international cryptocurrency-laundering operation allegedly serving a global cybercrime syndicate.
Washington is presenting the case as evidence that international law enforcement agencies can deanonymize suspects and seize cryptocurrency and other assets across borders.
A joint @FBI, @AusFedPolice and @WA_Police investigation has led to the arrest of two Western Australian men charged with allegedly hiding malicious code in open-source software, harvesting 500,000+ credentials and compromising 1,000+ organizations worldwide. A powerful example…

Australian suspects accused of targeting more than 1,000 organizations
Authorities arrested two Western Australian men in Perth: 21-year-old Reuben Ian Thomson and 23-year-old Louis Michael Gebler. Investigators allege that the pair coordinated a global cyber operation using a software supply-chain attack.
- Open-source software malware: The suspects allegedly embedded malicious code in legitimate, widely used software development tools.
- Global network access: The compromised software reportedly gave attackers covert access to the infrastructure of more than 1,000 organizations worldwide. Investigators say the operation resulted in the theft of 300 gigabytes of corporate data and 500,000 user credentials.
- Cryptocurrency laundering: Access to compromised networks was allegedly sold for cryptocurrency on underground darknet forums. Authorities say decentralized mixers and distributed chains of wallets were used to launder the proceeds.
During searches, investigators seized substantial cryptocurrency holdings and premium property allegedly purchased with the proceeds.
An Australian court has formally charged Thomson with intentionally dealing with proceeds of crime exceeding $100,000.
U.S. officials issue warning to the digital asset sector
U.S. officials are also using the case to warn cybercriminals and participants in the digital asset sector. FBI Deputy Legal Attaché Daud Andish said that “hiding behind a computer screen is no longer a shield from the rule of law.”
A statement from the U.S. diplomatic mission said the cross-border pursuit of cybercriminals and the disruption of cryptocurrency money-laundering channels align directly with the priorities of the current U.S. administration.
According to experts, the investigation underscores the FBI’s practice of pursuing illicit capital flows across geographical borders and sovereign jurisdictions.
