In 2025, the blockchain sector experienced 200 security incidents, resulting in losses totaling approximately $2.935 billion, marking a 46% increase from the previous year, according to SlowMist's data. DeFi platforms were hit hardest, with 126 incidents causing $649 million in losses. Trading platforms, despite only 12 incidents, suffered the most significant financial impact, with Bybit alone incurring a $1.46 billion loss. The primary causes of these breaches were contract vulnerabilities and social media account hacks. The rise in hacker group professionalism, the accessibility of RaaS/MaaS, and the use of Southeast Asian scams and privacy tools for money laundering have exacerbated the situation. In response, countries are enhancing AML/CFT measures and improving on-chain tracking and asset freezing capabilities through sanctions and cross-border enforcement.
