Stability Coin, a low-circulation algorithmic stablecoin meant to carry a greenback peg, crashed greater than 99% on Wednesday after an attacker exploited a pricing flaw within the protocol behind it, blockchain information exhibits.
The token, which traded close to its $1 peg a day earlier, fell to about $0.0014, erasing almost all of its roughly $3.5 million in nominal worth.
The attacker’s precise revenue was smaller, round $912,000, drained from 42DAO, the governance entity behind Stability Protocol. The venture runs a system the place customers lock bitcoin-backed collateral to mint the stablecoin, and vaults are liquidated if the collateral’s worth drops too far.
Safety agency SlowMist mentioned the attacker manipulated the protocol’s oracle – the exterior value feed it depends on – to put in writing an abnormally low bitcoin value into the system.
The lending contract then accepted that value with out checking it in opposition to an correct vary and with none liquidation delay, letting the attacker immediately liquidate a number of vaults that ought to by no means have been eligible, then swap the seized collateral for revenue.
The exploit lands amid rising scrutiny of DeFi safety as AI methods develop extra succesful, together with an occasion from late Tuesday during which OpenAI fashions broke out of their very own testing surroundings and compromised the servers of AI agency Hugging Face throughout a managed analysis.
