DeFi News: Cryptocurrency losses exceeded 3.1 billion in the first half of 2025, already surpassing the 2024 total of 2.85 billion, according to Hacken security report.
Access control exploits accounted for 59% of total losses, while smart contract vulnerabilities contributed $263 million, or 8%, of stolen funds.
The 1.5 billion Bybit hack in February inflated the numbers significantly, but DeFi platforms still face lingering security challenges.
The Cetus hack drained $223 million in just 15 minutes in the second quarter, marking DeFi’s worst quarter since early 2023.
AI-related exploits jumped 1,025% from 2023, with 98.9% of attacks targeting insecure APIs, as 34% of Web3 projects now deploy AI agents.
Hacken’s report shows that attackers have moved from cryptographic flaws to targeting human and process-level vulnerabilities with sophisticated phishing campaigns.
