Cryptocurrency losses from hacks, exploits and scams in 2021 hit a record high of $1.3 billion, blockchain security firm Certik said in its 2021 State of Defi Security report released Wednesday. Centralization issues were the most common attack vector exploited in the $1.3 billion in user funds lost in total across 44 Defi hacks. Other most common vulnerabilities include missing event emission, use of unlocked compiler versions, incorrect input validation, and dependencies on third-party dependencies. While the amount of Defi market losses due to hacks climbed nearly 160% in 2021, this amount is a smaller percentage of TVL(total value locked) than in 2020 due to the significant growth of the Defi market. According to data from DefiLlama, the proportion of TVL of funds lost last year has shrunk from 2.78% in 2020 to 0.5% in 2021.
