Crypto Hacks Surge 27% in July 2025: Backend Attacks and Social Engineering Cost $142 Million
The cryptocurrency industry faced a shocking wave of security breaches in July 2025, with losses skyrocketing to $142 million—a 27% increase from June. Backend attacks and social engineering tactics dominated these crypto hacks, exposing critical vulnerabilities in blockchain security.
Why Are Crypto Hacks Increasing in 2025?
July 2025 witnessed 17 major crypto hacks, with the most devastating being the $44 million CoinDCX breach. Unlike traditional smart contract exploits, hackers are now targeting backend infrastructure, which is often less audited and more vulnerable. Key factors driving this surge include:
- Backend vulnerabilities: Poorly secured server systems.
- Social engineering: Phishing attacks on employees.
- Lack of internal audits: Weak oversight in off-chain systems.
How Social Engineering Fuels Crypto Hacks
The $14 million WOO X phishing attack on July 24 demonstrated how hackers exploit human error. Blockchain security expert Rob Behnke warns that even advanced technical safeguards fail when trust is manipulated. Attackers:
- Compromised a team member’s device.
- Infiltrated the development environment.
- Executed unauthorized transactions undetected.
The Shift from Smart Contracts to Backend Attacks
Hackers are bypassing secure smart contracts and instead exploiting weaker backend systems. The $27 million BigONE hot wallet breach and the $40 million GMX exploit highlight this trend. Unlike decentralized protocols, backend systems often lack:
- Transparent audits.
- Multi-signature protections.
- Real-time monitoring.
Strengthening Blockchain Security Against Future Crypto Hacks
Experts emphasize a dual approach to combat rising threats:
- Technical upgrades: Multi-layered security controls.
- Human training: Regular cybersecurity awareness programs.
- Continuous audits: Proactive backend system checks.
