While Mohammed M. and his brother were cleared of all criminal charges, 7.8 million euros worth of crypto tokens became inaccessible after getting stuck in a wallet.
A French court has allowed two brothers responsible for the theft of $8.5 million from decentralized finance (DeFi) protocol Platypus to walk free with no repercussions.
On Feb. 16, hackers managed to drain and move $8.5 million from Platypus through a flash loan attack, forcing the protocol to suspend trading services until a resolution was found. Initial investigations identified the culprit as Mohammed M., who took advantage of a code error and withdrew all assets through an uncollateralized loan.

With the help of Binance’s security team and independent crypto investigators, the stolen funds were tracked, eventually leading to the hackers: Mohammed and his brother Benamar M.
The brothers had been held in custody since Feb. 24, and they admitted to stealing and siphoning the funds in an Oct. 26 court hearing — but claimed to be “ethical hackers.” They also told the Paris judicial court they had intended to return the funds in exchange for 10% of the loot.
Considering its similarity to a bug bounty attempt, the court cleared the brothers of all criminal charges. During the exploit, 7.8 million euros worth of crypto tokens became inaccessible after getting stuck in a wallet.
