ZachXBT assists in tracing $40 million in stolen crypto linked to a significant cyberattack on Brazilian banks, highlighting ongoing security challenges.
ZachXBT helped Brazilian law enforcement trace $30 million to $40 million in stolen funds linked to a cyberattack on major banks, part of a broader breach costing at least $140 million. The attackers converted a portion into Bitcoin, Ethereum, and USDT, laundering through local exchanges. ZachXBT successfully froze around $5 million in stolen crypto but criticized Circle for not assisting. Brazilian authorities arrested an employee for selling login credentials to hackers, with investigations ongoing for additional suspects.
