• July 2025 saw a 27% increase in crypto thefts compared to June, totaling $142 million across 17 attacks.

• The CoinDCX hack, involving a sophisticated server breach, accounted for the highest loss of $44 million.

• Security expert Rob Behnke highlighted social engineering as a critical factor in the WOO X $14 million phishing attack.

Crypto hacks surged to $142M in July 2025, led by CoinDCX’s $44M breach. Learn how social engineering and backend attacks threaten exchanges.

July 2025 Crypto Hacks Surge with CoinDCX Breach Leading Losses

Crypto thefts in July 2025 reached $142 million, marking a 27% increase from June’s $111 million, according to blockchain security firm PeckShield. The most significant incident was the CoinDCX hack, where a sophisticated server breach resulted in a $44 million loss. This breach underscores the growing threat of backend system vulnerabilities in the crypto industry.

WOO X Phishing Attack Exploits Social Engineering Tactics

Rob Behnke, chairman of blockchain security firm Halborn, reported that the WOO X hack on July 24 involved social engineering to compromise a team member’s device. Attackers leveraged this access to infiltrate the development environment, enabling multiple malicious transactions before detection. The attack affected multiple blockchains, including Bitcoin, Ether, BNB, and Arbitrum.

How Are Hackers Shifting Focus to Offchain Systems?

According to Behnke, hackers increasingly target offchain backend infrastructure rather than smart contract vulnerabilities, which are more easily audited. This shift demands stronger security controls and process improvements within crypto projects to mitigate risks posed by sophisticated attackers.

What Were the Other Major Crypto Hacks in July 2025?

Besides CoinDCX and WOO X, the BigONE exchange suffered a third-party hot wallet attack on July 16, losing at least $27 million. Additionally, the GMX decentralized exchange experienced a $40 million exploit, with the attacker returning the stolen funds days later, highlighting varied hacker motivations and tactics.
