CoinDCX Denies Fresh Hack After $16 Million USDT Transfer Flagged by Researchers

Indian crypto exchange CoinDCX has rejected claims of a new security breach after a security researcher flagged approximately $15.99 million in Tether moving out of wallets tagged to the platform. Co-founder and CEO Sumit Gupta said the addresses in question belonged to CoinDCX prior to its July 2025 hack and were compromised in that earlier attack, not in any new incident. He stated that no funds from the exchange's current wallets were affected and pledged that no user losses had occurred.

The denial drew some scrutiny from investigators, who noted that the flagged addresses remained linked to CoinDCX's operations, complicating the exchange's account of events. The episode underscores the persistent security and trust challenges facing crypto platforms, particularly those that have previously suffered breaches, as any large on-chain movement tied to a known exchange quickly attracts alarm.
