Solidity developer 0xQuit shared on X regarding details about Munchable. The developer identified that the good contract was a “dangerously upgradeable proxy with an unverified implementation contract.”

The exploit seemingly wasn’t “nothing complicated” because it consisted of asking the contract for the stolen funds. Nonetheless, it required the attacker to be a certified celebration, confirming that the heist was a scheme carried out contained in the mission.

After a deep dive into the matter, 0xQuit concluded that the assault had been plotted since deployment. Munchable’s developer used the contract’s upgradable nature to “assign himself an unlimited ether stability earlier than altering the contract implementation to 1 that appeared legit.”
