This contract could drain you even without active listing, by any address that have the DELEGATE_CALLER role (actually only the marketplace contract). BUT the admin role have the power to add new delegate callers and there is actually only a EOA address that have such power.

WOW!!!! @nomadxyz_ was able to freeze the contract by just removing the Replica contract as owner. They did it, but 2 hours too late and they knew about it when the contract had around $125m funds LOOOOL

"MOS" got exploited for $18000, the original exploiter got frontrunned and then begs the frontrunner for some profit LMAO Storys that only happen in crypto.

(8/9) With a nervous hand and a sense of urgency, I went to Etherscan's "Write Contract" tab for WETH to secure the 66 $ETH from the arbitrage bot. Additionally, I utilized a brute-forced address that closely resembled the attacker's address to hide it even more.

1. Tell a botter like user221 the new "captchas" that he can generate the signatures to mint. 2. Start the sale as promised at 12pm EST. 3. update the website 1 minute later to give your insider bot enough time to mint. Made a screen of the timeline to visualize it.
