July 2025 Crypto Hacks Surge 27% to $142M as CoinDCX Suffers $44M Breach

Cyber attacks on the cryptocurrency industry in July 2025 caused at least $142 million in losses across 17 incidents, according to blockchain security firm PeckShield [1]. The total represents a 27% increase from June 2025’s $111 million in losses but remains 46% lower than the $266 million stolen in July 2024 [1]. The most significant breach occurred when Indian exchange CoinDCX was targeted on July 18, resulting in a $44 million loss attributed to a “sophisticated server breach.” A company employee was arrested in connection with the incident [1].

Earlier in the month, the decentralized exchange GMX v1 was exploited for $40.5 million on July 11. However, the attacker returned the stolen funds a few days later [2]. On July 16, crypto exchange BigONE suffered a third-party attack targeting its hot wallet infrastructure, leading to a loss of at least $27 million [1].

WOO X, a crypto trading platform, ranked third in the month’s largest breaches after a phishing attack on July 24 resulted in a $14 million loss [1]. According to blockchain security expert Rob Behnke from Halborn, the attackers used social engineering to compromise a team member’s device, allowing them to exploit the system’s trust mechanisms and siphon funds across multiple blockchains, including Bitcoin (BTC), Ether (ETH), BNB (BNB), and Arbitrum (ARB) [3]. The attack lasted for two hours before the platform disabled withdrawals and restored affected account balances using its treasury [1].

Behnke highlighted that attackers are increasingly shifting their focus from on-chain smart contract vulnerabilities to off-chain infrastructure and processes [3]. This trend indicates a growing sophistication in DeFi-related cyber threats, which require stronger backend security controls to prevent.

The July 2025 data underscores the evolving nature of crypto security risks, with attackers leveraging a combination of technical and social engineering tactics. As the industry grows, so does the need for firms to reinforce both their digital and human infrastructure to mitigate such incidents [1].
