Promote with Leviathan NewsHTX (formerly Huobi) and its associated Heco cross-chain bridge suffered a significant security incident in late November 2023, when attackers drained tens of millions of dollars from the Heco Chain bridge and from HTX hot wallets. Blockchain security firms such as PeckShield, CertiK, Cyvers, and others observed large, suspicious outflows of assets including USDT, ETH, HBTC, USDC, LINK, UNI, SHIB, and TUSD, with estimates of total losses ranging from roughly $99 million to around $110 million across the bridge and exchange wallets. Analysis indicated that the Heco bridge operator wallet’s private key was likely compromised, allowing the attacker to initiate legitimate-looking withdrawals from the bridge, while a separate but closely timed exploit hit HTX hot wallets following a similar pattern. Justin Sun, an HTX stakeholder and board member, acknowledged the incident publicly on X, stating that HTX and the Heco cross-chain bridge had undergone a hacker attack, that deposits and withdrawals were being temporarily suspended, and that HTX would fully compensate users for losses from its hot wallets. Sun and HTX emphasized that user funds on the platform were secure and pledged that the exchange itself would cover the losses, with normal operations to resume after the completion of an internal investigation. The hack added to a growing series of security breaches involving Sun-linked platforms, and it highlighted once again the systemic vulnerabilities of cross-chain bridges, which have accounted for a large share of total value lost to Web3 hacks and remain a critical weak point in crypto infrastructure.
