Binance hack triggers crypto sell-off as BNB plunges following record $6.3bn breach
Crypto markets tumbled after a suspected Binance hack involving approximately $6.3bn in digital assets came to light. The historic breach sent the exchange's BNB token sliding sharply and pushed major cryptocurrencies into negative territory.
⚡ Key numbers:
- $6.3bn — total assets impacted during the security breach
- 7% — immediate decline observed in BNB token prices dryer than before loss acceleration

Unprecedented security breach hits top crypto platform
The world's largest cryptocurrency exchange confirmed an extensive security breach that affected roughly $6.3bn in digital assets. Platform administrators quickly halted all deposits and withdrawals to contain unauthorized transactions, pledging to cover all customer losses from internal reserves. Initial reviews suggest attackers executed illicit withdrawals after compromising a DevOps engineer's work laptop.
Leading stablecoin issuers acted quickly to limit contagion: Tether locked down approximately $1.6bn, while Circle confirmed freezing over $800m tied to suspicious addresses.

Investigators link massive heist to North Korea's Lazarus Group
Blockchain intelligence firm TRM Labs stated with high confidence that the cyberattack was executed by TraderTraitor, a specialized division linked to North Korea's state-backed Lazarus Group. The theft eclipses the previous historic record set in 2025, when Bybit lost $1.5bn in a similar intrusion. Blockaid chief executive Ido Ben-Natan noted that attackers manipulated transaction-signing systems rather than executing straightforward private key theft.
“When North Korea steals at this scale, the money funds weapons proliferation and other destabilising activity. That makes this a global security issue, not just a crypto theft”

BNB token slides as broader market sentiment weakens
BNB led the market downturn, shedding more than 6% within an hour of the news before deepening losses past 7%. The wider sell-off spilled into major benchmarks, pulling Bitcoin down below $77,000 before steadying near $78,128, a 3.86% dip, while Ethereum traded down 4.97% at $2,240 according to Yahoo Finance data.
Sean Foley, an academic expert at Macquarie University, highlighted to Al Jazeera that damaging retail confidence in the world's most prominent centralized exchange risks cooling asset prices across the board. Institutional traders also reacted by pulling capital from secondary trading venues as systemic fears mounted.
