QANplatform's bridge deployer wallet was compromised on October 11, 2022 due to the profanity vulnerability in the vanity address generator. The attacker recovered the private key and drained ~$2M from the Ethereum and BNB cross-chain bridges in multiple withdrawals.

Layer1 blockchain QANplatform (QANX), which is resistant to quantum computing attacks, tweeted that its smart contract cross-chain bridge was attacked, and the attacker managed to extract tokens, reminding users not to perform any transactions related to QANX tokens. According to the findings, the hackers obtained the private keys to the bridge wallet and withdrew more than 1.4 billion QANX tokens worth more than $1 million in two transactions.
