Update to White House reviews Binance breach as calls grow for stricter crypto rules
Confirmed by independent sources.
The FBI confirmed on October 31 that it joined the investigation into Binance's hot wallet breach, which drained between $5.3 billion and $6.36 billion across 10 networks.
On October 31, 2026, U.S. federal law enforcement agencies confirmed they joined the investigation into unauthorized asset transfers from Binance hot wallets that began at 20:05 UTC on October 29. As previously reported, the White House acknowledged regulatory scrutiny following the breach, which an FBI spokesperson confirmed the bureau is coordinating with partners to assess. Blockchain analytics firm TRM Labs reported that the attack drained approximately $5.3 billion to $6.36 billion across 10 blockchain networks, including Ethereum, Bitcoin (BTC), Tron, Solana (SOL), XRP Ledger, Avalanche, and Polygon.
TRM Labs attributed the intrusion to TraderTraitor, a North Korea-linked hacking group that deployed exploit code directly to a Binance hot wallet after testing it on prior test wallets. The unauthorized transfers started on the XRP Ledger before expanding to networks including Ethereum, which accounted for roughly $3.79 billion in losses, and Bitcoin, where 18,270 BTC worth about $1.47 billion was taken. Binance temporarily suspended withdrawals across several networks as a precaution while stating that user funds remain safe.
