Crypto Hacks in 2025 Hit $3.3 Billion, Fewer but Bigger Attacks

Crypto hacks stole a total of $3.3 billion in 2025, but the number of attacks fell sharply compared to previous years, according to blockchain security firm CertiK. The decline in incident counts suggests that improved protocol-level security is pushing hackers toward more sophisticated, high-value exploits.

Supply-chain breaches were the most damaging, accounting for $1.45 billion in losses across just two incidents—including the massive $1.4 billion Bybit hack. CertiK warns that well-coordinated threat actors are increasingly targeting infrastructure providers, signaling a new era of complex, high-stakes attacks.
