Crypto Losses Exceed $3.1 Billion in H1 2025 Amid Security Challenges
- Over $3.1 billion in cryptocurrency was lost in the first half of 2025, surpassing the total of $2.85 billion from all of the previous year.
- Access-control vulnerabilities accounted for approximately 59% of total losses, while smart-contract bugs contributed to around $263 million.
- The Cetus hack resulted in a loss of $223 million, marking DeFi’s most significant exploit since early 2023.
- AI-related security threats surged by over 1,025%, with nearly all attacks linked to insecure APIs.
- Operational security flaws led to $1.83 billion stolen across decentralized finance (DeFi) and centralized finance (CeFi) platforms.
The crypto sector is facing escalating security issues, with access control remaining a critical vulnerability despite advancements in technical safeguards. The shift towards exploiting human and process-level weaknesses highlights the need for improved security measures across the industry.
In just six months, losses have already reached over $3.1 billion, emphasizing the urgent need for enhanced protections against evolving threats in both DeFi and centralized platforms.
