Another Reentrancy Hack
As explained by the blockchain security company PeckShield on Twitter, Thursday’s hack was made possible “due to incomplete reentrancy protection.” A reentrancy bug refers to when an attacker may withdraw funds repeatedly from a smart contract at no cost.

In this case, the hacker used a newly constructed token called ATK, and a self-destructing smart contract, to manipulate Orion’s pools.

After hack, the gain of 1100 ETH is deposited into @TornadoCash and other 657 ETH stays in the hacker’s account: https://t.co/wGG6RA0qii pic.twitter.com/lRj9HGEgQc
