The BitBTC bridge reportedly had a bug that would essentially allow an attacker to mint fake tokens on one side of the bridge and swap them for real ones. However, one Twitter user was able to foresee the vulnerability and informed the cross-bridge platform about it.
The Moola Market attacker has scored about a half-million dollar “bug bounty” after choosing to return a majority of the cryptocurrency they exploited from the Celo-based lending protocol. Cryptocurrency market maker Wintermute repaid a $92 million TrueFi loan on time despite suffering a $160 million hack.
Mango Market hackers that returned a significant chunk of the $117 million stolen from the protocol could still face legal action despite the protocol deciding to award him a $50 million bounty. The top 100 DeFi tokens remained bearish for another week, as the majority of the tokens traded in red, barring a few. The total value locked also remained below $50 billion for the second consecutive week.A cross-chain bridge between BitBTC and the Ethereum layer-2 network Optimism has been able to avoid a potentially costly exploit thanks to the work of an eagle-eyed Twitter user.
