December 9, 2019 Developer flags potential MakerDAO governance attack vector.

Micah Zoltu, an independent developer and a co-author of the original Augur whitepaper, describes an attack in which MKR holders could withdraw ETH and other cryptoassets collateralizing the DAI stablecoin. The key aspect to the described attack is that governance changes, as voted on by MKR holders, currently have no delay to be implemented once voted in. Thus, in theory, user(s) with a large MKR holding could alter the smart contracts rapidly and withdraw funds. According to the Maker Foundation, this issue has been considered in detail by the community, who view this more flexible approach as appropriate to respond to issuing arising from the cut over to Multi-Collateral DAI.
