The attacker quickly bridged the tokens to the Ethereum chain and swapped them for ETH and USDC, collectively worth around $1.7 million. The price of ALBT plunged around 50%, and the BEUR Euro-pegged stablecoin significantly lost its peg.
Bonq defi borrowing project exploited
Pando exploited for $20 million
Oracle attack on Solend costs the project $1.26 million
Oracle manipulation attack on a QuickSwap market earns exploiter $188,000
Security firm PeckShield initially suggested the issue might have been with QiDAO, which creates the $MAI stablecoin. The vulnerability is not with their project, although it's possible that the theft will impact the collateralization of their stablecoin.
Moola Market exploited for $8.4 million
This attack was executed similarly to the Mango Markets exploit a week prior. Moola Market tweeted that they had "contacted law enforcement and taken steps to make it difficult to liquidate the funds. We are willing to negotiate a bounty payment in exchange for returning the funds within the next 24 hours." The attacker did eventually return 93% of the funds, keeping the remaining $588,000 as a "bug bounty".
Mango Markets suffers loss of more than $116 million
Mango Markets posted on Twitter to urge users not to deposit into the project, and asked the hacker to contact them "to discuss a bug bounty". The hacker had their own plans, instead submitting a governance proposal in which they would return $46 million of the stolen funds (keeping $70 million) in exchange for a promise that the protocol would not try to freeze the assets or pursue criminal charges. The hacker then used their 32 million governance tokens to vote in support, but ultimately were not able to get the proposal to pass. A different proposal with largely the same terms, but which left the attacker with only $47 million of the stolen funds, passed shortly after.
