Web3 Security Crisis Deepens with $3.1B Losses and AI Attack Surge

Web3 platforms suffered $3.1 billion in losses during the first half of 2025, eclipsing total 2024 losses, according to Hacken's security report. Access control failures dominated the exploit landscape, accounting for $1.83 billion, while phishing and smart contract vulnerabilities contributed $600 million and $263 million respectively.

AI-powered attacks emerged as a critical threat vector, with incidents skyrocketing 1,025% compared to late 2024. The report highlights growing vulnerabilities in AI inference layers and APIs as threat actors increasingly weaponize machine learning tools.

DeFi endured its worst quarter since early 2023, with protocol design flaws and social engineering schemes compounding the security crisis. The findings underscore the urgent need for enhanced security frameworks as Web3 adoption accelerates.
