Cover protocol hack analysis: Infinite Cover tokens minted via an exploit

A bug was exploited in the Cover protocol’s liquidity mining/farming contract called Blacksmith. Multiple hackers used the bug to mint practically infinite tokens. The biggest hacker burned most of the hacked tokens and returned 4350 ether but there still are around 70 thousand Cover tokens in circulation that were created using this exploit and shouldn’t exist. The original hacker has cashed out about 1400 ether, 1 million DAI, 3k LINK, and 90 WBTC, about $4.4 million in total already.
