FBI and US Secret Service work with Binance after $6.3 billion hack Binance is reportedly coordinating with the FBI and US Secret Service after a record $6.3 billion hack. The title indicates a joint response involving both federal investigators and exchanges following a major breach. Operationally, the case places a private crypto platform within an active framework of US law enforcement, with implications for money tracing, seizure efforts and cross-border cooperation. The scale alone makes this a key stress test for exchange security, incident response and the state's ability to track illicit crypto flows. Open sources - closed narratives.
