CoinDCX Confirms $16 Million Loss from Failed Sweep of Retired Post-Hack Wallets
What happened
Mumbai-based exchange CoinDCX absorbed a $16 million operational loss after an automated sweeping failure allowed customer deposits to pile up in deprecated wallets that were subsequently drained.
The Context
* Legacy vulnerabilities lingered following an initial July 2025 breach that cost the platform $44 million, prompting the exchange to retire TRON deposit addresses that users continued funding. * Sweeping automation broke down across 40 deprecated addresses, stalling scheduled transfers to secure custody and permitting an attacker to siphon 15.99 million USDT and 5,784 TRX. * Corporate reserves absorbed the hit to credit affected balances and maintain normal trading, while issuer Tether stepped in to freeze $2.21 million of the drained assets on-chain.
The Number
— the volume that accumulated in supposedly dead infrastructure, proving that poor operational hygiene can breach treasury reserves without touching cold storage.
Takeaway
Expect centralized exchanges to accelerate forced migrations away from retired deposit paths as on-chain auditors increase scrutiny on ghost infrastructure.
