Data sourced from DefiLlama & SunWeb3Sec/DeFiHackLabs . Thank you for keeping Web3 security data open.
The most expensive crypto hacks are not random. They cluster around repeating vulnerability patterns: access-control failures, flash-loan manipulation, oracle abuse, and unsafe external calls. Studying large-loss incidents helps security researchers prioritize high-impact threat models first.
For deeper context, explore the full Web3 Hacks Dashboard and our Smart Contract Attack Library for hands-on exploit and mitigation breakdowns.
Incidents are ranked by parsed USD amount lost in descending order. Records without parseable loss values are excluded from this ranking.
It includes all incidents with known loss values in the database. Use the full dashboard for broader filtering and lower-severity incidents.
Study attack-class pages first, then practice in guided exercises inside the Smart Contract Hacking course.
$101B+ lost to preventable vulnerabilities. Master real exploit patterns and defense techniques with hands-on Web3 security training.
