Hi @Poloniex, you may want to take a look: @justinsuntron etherscan.io/address/0xa910…



#PeckShieldAlert Suspicious huge withdrawal of 10,145 $ETH (~$19m) from #Heco_Bridge. @justinsuntron Note the tx is initiated by the operator. Looks like a compromised operator? etherscan.io/tx/0xbb6fe8842…







The OpenZeppelin team was informed yesterday Monday (12/4) at 4pm ET by @thirdweb about a security vulnerability involved in but not limited to Thirdweb’s versions of DropERC20, ERC721, ERC1155 (all versions), and AirdropERC20 pre-built contracts. As far as we know, this vulnerability has not been exploited. Based on our investigation, the issue is inherent to a problematic integration of specific patterns, and NOT particular to the implementations contained in the OpenZeppelin Contracts library. Nonetheless, we will lead the effort to assess who in the community is affected and provide them with mitigation strategies. At the appropriate time, we will responsibly disclose this vulnerability following best practices for the safety of the community. For Thirdweb users, they have developed a tool to check whether contracts created through their platform are affected and perform a migration: mitigate.thirdweb.com
