Last month, the contracts powering Magic Eden were exploited to the tune of millions of dollars. I was lucky enough to be in a position to rescue a good portion of that, but it highlighted the danger of leaving approvals open as adversaries get access to better and better tools for finding holes in contract logic. Today, Blur announced that they will be deprecating their frontend. I've investigated Blur and found no exploits within the current contracts. However, the Blur contracts are upgradable, meaning that they could turn malicious at any time. They currently have eight figures worth of NFTs approved to them. The safety of those NFTs effectively hinges on the opssec of the Blur team, which appears to be disbanding at this time. If you have open approvals to Blur, I recommend you remove them immediately. Use revoke.cash or similar to ensure that you are protected in case of a contract exploit or later upgrade. Don't wait. The time is now.

At 9AM EST today somebody abused a bug in Payment Processor V2 to steal 10 Meebits, 50 Otherdeeds, 10 WoW, and 235 Desperate Apewives. It wasn't until over 12 hours later that somebody reported it to me, and upon digging in I realized that a great many NFTs were subject to the same exploit. I got in touch with the team over at LimitBreak and they quickly paused Payment Processor V3, which was subject to the same exploit. Unfortunately, V2 was not pausable, so the only path towards protecting affected assets was to run a whitehat operation. Similarly, V3 on ApeChain is temporarily in a state where it cannot be paused, so ApeChain assets approved to V3 needed to be saved as well. All in all, we rescued 23,155 NFTs worth north of $5.7M USD. We later discovered that a similar exploit could be used in reverse to steal WETH. 660 WETH was at risk, which we unfortunately were not fast enough to recover. Apologies to those affected. Shout out to @Boomskite for flagging the initial exploit tx to me, and @coffeedev @0xjustadev and @whiteoakkong for acting quickly and assisting with the recovery. All NFTs are safely relocated. Soon, owners will be able claim them back after revoking the exploitable approvals. Addresses to revoke below.
