DeFi News: Crypto Hacks Surge Past 3.1B in 2025 as Access Control Flaws Persist

Cryptocurrency losses exceeded 3.1 billion in the first half of 2025, already surpassing 2024's total of 2.85 billion, according to Hacken's security report.

DeFi News: Cryptocurrency losses exceeded 3.1 billion in the first half of 2025, already surpassing 2024's total of 2.85 billion, according to Hacken's security report.

Access-control exploits drove 59% of total losses, while smart-contract vulnerabilities contributed 263 million or 8% of stolen funds.

The 1.5 billion Bybit hack in February significantly inflated the numbers, but DeFi platforms continue facing persistent security challenges.

The Cetus hack drained 223 million in just 15 minutes during Q2, marking DeFi's worst quarter since early 2023.

AI-related exploits surged 1,025% compared to 2023, with 98.9% of attacks targeting insecure APIs, as 34% of Web3 projects now deploy AI agents.

Hacken's report shows attackers shifted focus from cryptographic flaws to targeting human and process-level vulnerabilities through sophisticated phishing campaigns.
