Ethereum Remains the Primary Target in 2025 Blockchain Security Report, Suffering Approximately $254M in Losses as DeFi Attacks Account for 63% of Incidents
According to SlowMist via COINOTAG, 2025 closed with roughly 200 security incidents and $2.935 billion in losses. By contrast, 2024 logged 410 incidents and $2.013 billion, marking a decline in incidents but a 46% rise in losses year over year.
Ecosystem losses show Ethereum as the most impacted, with about $254 million in annual loss, followed by BSC at $21.93 million and Solana at $17.45 million.
DeFi remains the primary attack vector: 126 DeFi incidents (about 63% of the total) and $649 million in losses, down from 339 incidents and $1.029 billion in 2024.
Exchanges suffered 12 incidents but incurred a heavy toll of $1.809 billion, with Bybit bearing about $1.46 billion in a single event—the year’s most severe breach.
Root causes center on contract vulnerabilities (61 cases) and X account breaches (48). The report notes AI-enabled fraud, where generative AI lowers attack costs and creates convincing content.
