Cryptocurrency analytics firm Elliptic has announced report A new report shows that $ 12 billion has been stolen from the DeFi sector in the past two years, most of it at $ 10.5 billion this year.
Most of it was the result of a protocol bug, a loss of $ 10 billion related to tokens that have depreciated in market value due to fraud.
Only $ 2 billion was stolen in attacks targeting DeFi projects directly. This type of incident includes the recent attacks on Anubis DAO and Cream Finance.
Elliptic notes that $ 721 million in lost funds of this type was eventually recovered, making the category less important.
Different attack strategies and types of application
The attackers who carried out DeFi attacks used different strategies. Losses of $ 5.5 billion came from code exploitation and another $ 5.3 billion from economic vulnerabilities. Exploitation of the Admin Key vulnerability resulted in losses of $ 1 billion, while the rug pull or exit fraud amounted to only $ 18 million.
Different types of DeFi applications are sought to different degrees. Loan applications account for 34%, DEXs for 17.1%, asset management applications for 16.4% and cross-chain bridges for 13.5%.
The metric calculated by Elliptic is based on two large series. Ethereum-based DeFi applications accounted for 71% of the total at $ 8.6 billion, while Binance Smart Chain (BSC) -based applications accounted for 21% at $ 2.5 billion.
Other estimates of DeFi attacks
Elliptic’s numbers are higher than estimates for other companies. In August, CipherTrace claimed that DeFi crime caused $ 361 million in losses in 2021 and $ 129 million in 2020.
The live data tracker from The block suggests that $ 629 million has been stolen by DeFi exploits since 2020.
These differences may suggest that Elliptic did a closer look at the DeFi grounds than its competitors. On the flip side, including the decline in token value could have increased its estimate.
