According to The Block, the U.S. Department of Justice revealed that an undercover FBI law enforcement officer sent a private message to "IntelBroker" seeking to purchase a victim's data for $250 worth of Bitcoin ($BTC), successfully locating and arresting Kai West (online alias "IntelBroker"), who is suspected of multiple corporate data breaches. The suspect, who primarily used Monero for black market transactions, was arrested in France this February and is currently awaiting extradition. The FBI alleges that between 2023 and 2025, he attempted to sell at least 41 hacked datasets, causing a total loss of over $25,000,000. Blockchain forensics company TRM Labs stated that this case demonstrates the breakthrough progress of blockchain forensics in cryptocurrency crime investigations. [ChainCatcher]
