Grand Base, a DeFi market on Base that focuses on synthesising and tokenising real-world assets, experienced a $2 million exploit, due to a leak of a private key associated with one of the deployer wallets.
Behind the Breach
The exploit was facilitated through unauthorised access to one developer's PC where the private key of the deployer wallet was stolen. Once compromised, the attacker minted and sold 32.5 million GB tokens worth approximately $2 million.
