Hackers usually use flash loans to amass huge management of a given protocol’s governance token, permitting them to move malicious protocol adjustments. Such assaults netted $233 million in Q2 – greater than every other hacking methodology.

Another $131.15 million have been misplaced to compromised personal keys, round which safety “continues to be a concern.”

BNB Chain: King of Hacks

As the longtime king of defi, Ethereum was residence to $381.35 million in losses final quarter – greater than every other chain. According to Defi Llama, almost $48 billion remains to be locked in defi protocols on Ethereum, out of $77.11 billion throughout all the ecosystem.

The community noticed a major restoration in defi’s market share following Terra’s collapse – the previous quantity 2 defi community. The new runner-up is Binance Smart Chain (BSC; aka BNB Chain), which holds simply $6.21 billion locked.

However, when damaged down by the quantity of main assaults, BNB chain accounted for 26 – greater than half of them. The chain joins Ethereum, Fantom, and Cronos as having suffered main assaults for 2 quarters in a row. By distinction, Solana was walloped with $374 million in losses throughout two exploits in Q1 however suffered no main assaults in Q2.

Unsurprisingly, over half of the stolen funds in Q2 ($418.89 million) have been transferred to Tornado Cash – a cryptocurrency mixing service that helps thieves cowl their tracks on the blockchain. Of these funds, $131 million in property have been recovered.
