Ola Finance Exploited for $3.6M in Re-Entrancy Attack

The attacker began by withdrawing funds using Tornado Cash, which enables users to transfer crypto without leaving a trace. After transferring the funds to the Fuse network, the borrower used them as collateral to take out loans on Ola’s decentralized lending platform. Taking advantage of the re-entrancy bug, the attacker was then able to remove the collateral without first paying back the loan.
