Police seized over 40 pieces of evidence, including mobile phones, laptops, and digital wallets. The suspects face charges of Conspiracy to Commit an Offense Against the United States and Conspiracy to Commit Wire Fraud.

The arrests stemmed from an urgent international cooperation request from Swiss authorities and the United States, involving Interpol warrants for the European suspects who had entered Thailand as part of a transnational criminal organization.

The group deployed Phobos ransomware against 17 Swiss companies between April 30, 2023, and October 26, 2024. Their operation involved unauthorized access to victims’ networks, data theft, and encryption of files. The hackers demanded cryptocurrency payments for decryption keys and threatened to publish stolen data if ransoms weren’t paid.  They also used cryptocurrency mixing services to obscure transaction trails.

The operation has affected over 1,000 victims worldwide, causing damages estimated at $16 million (approximately 560 million baht). While the suspects are in custody with evidence, their identities remain undisclosed as investigations continue.
