Exploit: MakerDAO ETH-A Liquidation Keeper Bot ($538K)
A MakerDAO ETH-A liquidation keeper bot on Ethereum was described as having lost $538,000 in one account of the incident and $538K in another. The event was framed as an improper access control issue in one piece and as a smart contract vulnerability in the other.
What this rests on
What it means
Each sentence links inside to the piece that supports it.
MakerDAO ETH-A liquidation keeper bot activity on Ethereum is the part that would be visible to users and operators watching this space, because one account of the event says $538K was lost and another labels the incident a smart contract vulnerability. The practical effect today is that the incident is already public in two forms, with the bot and chain named outright.
Before this incident was described, the bot was presented as operating on Ethereum; after it was described, the same event is now tied to an access-control problem in one account and a smart-contract vulnerability in another. What does not change from these descriptions is that the chain remains Ethereum and the incident is attached to the MakerDAO ETH-A liquidation keeper bot. (per thecryptoguardian.com)
