BlockThreat - Week 26, 2021

Haven | ThorChain | Merlin | NFTX

Welcome back to the Blockchain Threat Intelligence newsletter! After a brief vacation, I’m catching up with the world of blocksec which never stops to amaze me. This week we witnessed a relatively rare minting exploit in a blockchain protocol which resulted in the loss of more than $4.5M. On the more traditional DeFi side, Merlin was exploited yet again with the now common reward calculation bug followed by NFTX marketplace losing 2 CryptoPunks due to a logic error.

Let’s dive into the news, but first a special thank you to Trail of Bits which sponsored this week’s edition:
