A 35-year-old Russian national, suspected of orchestrating cyberattacks on U.S. and European government agencies, has been arrested in Phuket, Thailand, following a tip from the FBI. The suspect, identified as Denis Obrezko from Stavropol, entered Thailand on October 30 and was apprehended earlier this month at his hotel. Thai authorities seized laptops, mobile phones, and digital wallets during the arrest, with FBI officials present. Obrezko is now detained pending a potential extradition to the United States. Russian state media confirmed the arrest, and his relatives are reportedly planning to contest the extradition. The U.S. Department of Justice and State Department have declined to comment on the case. Russian diplomats have visited Obrezko in custody, and the Russian consulate in Phuket acknowledged the arrest but provided no further details. The extradition process is underway, though its duration remains uncertain.
