Europol stated that law enforcement agencies have seized the group's servers and leak site, securing at least 110 TB of stolen data. The operation involved searches of eight locations in Spain, Greece, Romania, and the UK, investigating approximately 1,000 suspected global attacks, of which around 500 have been confirmed successful. Additionally, two suspects in their 20s were arrested in the UK and Romania, while a Dutch national residing in the UK was indicted and arrested in Puerto Rico, awaiting extradition.
