The takedown involved the U.K. National Crime Agency (NCA), the U.S. Federal Bureau of Investigation (FBI), Europol, as well as agencies from Bavaria, Belgium, Czechia, France, Germany, Japan, Romania, Spain, Switzerland, and Thailand.

Thai media reports have revealed that four European nationals – two men and two women – were arrested across four different locations on Monday as part of an effort codenamed Operation Phobos Aetor. The identities of the suspects were not disclosed.

Authorities are said to have seized more than 40 pieces of evidence, including mobile phones, laptops, and digital wallets.

They are alleged to be linked to the deployment of Phobos ransomware against 17 companies located in Switzerland between April 2023 and October 2024. Furthermore, the group has been accused of earning $16 million through attacks that claimed over 1,000 victims across the world.

8Base, which emerged as a major double extortion player in 2023, has been previously found incorporating Phobos ransomware artifacts into their financially motivated cyber attacks, with research from VMware uncovering a Phobos sample using a “.8base” file extension on encrypted files.

Overlaps have also been identified between 8Base and RansomHouse, particularly when it comes to their ransom notes and dark web infrastructure.

The latest development comes in the aftermath of a series of high-profile disruptions associated with Hive, LockBit, and BlackCat in recent years. Late last year, Evgenii Ptitsyn, a 42-year-old Russian national believed to be the administrator of the Phobos ransomware, was extradited to the U.S.
