BTCTurk Hack has once again rattled the cryptocurrency world as the Turkish exchange halted withdrawals following a suspected $48 million exploit. The breach, detected on August 14, 2025, involved over 90 types of tokens being siphoned from the exchange’s hot wallets across multiple blockchains including Ethereum, Avalanche, and Solana.
Details of the Exploit
The attack appears to be a sophisticated multi-chain exploit, likely involving a private key compromise or insider access. The hacker swiftly moved funds into two Ethereum addresses and one Solana address. Over $34 million was converted into Ethereum using MetaMask swaps and decentralised exchanges such as PancakeSwap.
The Solana wallet, active since June 2025, transferred $6.09 million, including meme coins and stablecoins, through an intermediary known as “PNUT Whale.” The hacker’s strategy demonstrated high sophistication, utilising rapid swaps and routing funds across Solana, BNB Chain, and other networks to avoid detection.
BTCTurk’s Response
BTCTurk responded by halting cryptocurrency deposits and withdrawals, citing a “technical issue” during routine checks. Trading and Turkish lira transactions remain operational, with assurances that most assets are secure in cold wallets. The exchange confirmed no personal user data was compromised.
Authorities have been notified, and BTCTurk is collaborating with blockchain security firms like Cyvers to investigate. However, no timeline for resuming crypto operations has been provided.
Context and Industry Impact
This incident marks BTCTurk’s second major breach in 14 months, following a $55 million exploit in June 2024. The exchange’s security practices have been under scrutiny, with critics pointing to its limited liquidity and security features.
The hack coincided with a market downturn, with Bitcoin at $118,000 and Ethereum at $4,539.83. The broader crypto industry has seen over $2 billion in losses due to hacks in 2025.
Despite the breach, no significant recovery of stolen funds has been reported, although Binance had previously frozen $5.3 million in a prior BTCTurk hack in 2024.
