Binance confirmed a hack after large outflows from its hot wallets on Oct 29.

Its initial finding at 02:25 UTC Oct 30 points to a compromised DevOps engineer's laptop used to reach a service container and submit unauthorized withdrawals, with no wallet key leak found so far.

Binance puts impact around $6.3B with about $3B frozen onchain with partners, and says deposits and withdrawals stay suspended while it freezes funds and works with law enforcement. It pledges to cover all losses via SAFU and company funds.

Tether CEO Paolo Ardoino confirmed Tether froze more than $1.567B USDT linked to the hack. Trackers put Circle's USDC freeze around $823M, for about $2.39B in stablecoins frozen plus other assets.

Onchain tallies cited about $5.6B outflows including $1.45B BTC, $875M ETH, $1.57B USDT and $823M USDC. BNB traded about $710.46 on Binance spot at 03:13 UTC Oct 30, down about 5% in 24h.
