The FBI has arrested British national Kai West, known online as IntelBroker, for allegedly selling stolen data on cybercrime forums. West is accused of causing over $25 million in losses through his activities. The U.S. Attorneys Office for the Southern District of New York has charged him following a sting operation where an undercover officer purchased victim data for $250 in Bitcoin. The transaction led to West's identification and subsequent arrest in France. The U.S. is now seeking his extradition.
