Bridge authority credentials were compromised, allowing extraction of 4.4M QANX tokens (370 ETH, ~$707K at time of exploit). The attacker traded stolen tokens through DEX, achieving significant liquidation of the position.

On May 18, QANX Bridge was attacked between 15:01:40 and 18:20:25 UTC. Developers can withdraw 100,450,000 QANX from QANX Bridge and sell it on Uniswap for 325 ETH, then transfer it to Tornado Cash. By May 26, the hackers had sold all the stolen QANX tokens.
