DeFi exploits across blockchains worldwide totaled $3.64 billion in 2022. This represented a rise of 47.4% compared to the loss of $2.44 billion in 2021. The incidents increased in quantity despite a steep 80% loss in DeFi total value locked during the year. 

Out of the 2022 amount, funds lost during cross-chain bridge hacks amounted to $1.89 billion across 12 incidents — the highest in the category. Overall, attacks on the Ethereum, BNB, and Solana chains accounted for the majority of exploits.

Out of the 167 notable incidents in 2022, 51.5% of breaches occurred in audited projects, while 48.5% of breaches occurred in non-audited projects. In total, LianAn said 38.7%, or $1.40 billion, of stolen funds were laundered via cryptocurrency mixer Tornado Cash. Only $289 million worth of funds have been recovered throughout the year. However, the number is likely higher as several recoveries have yet to be publicly disclosed per law enforcement request.
