Algorithmic Stablecoin Balance Coin Suffers Oracle Attack, Plummets 99%
According to CoinDesk reports, algorithmic stablecoin Balance Coin suffered an oracle price manipulation attack on July 22. The coin price plummeted from near the $1 peg to about $0.0014, a drop of over 99%, and the nominal market cap of about $3.5 million nearly went to zero.
According to analysis by security firm SlowMist, the attacker fed abnormally low false Bitcoin prices into the protocol, bypassing price rationality checks and liquidation delay mechanisms. They forcibly liquidated multiple ineligible collateral vaults in a single transaction, subsequently exchanged the acquired collateral for arbitrage, and ultimately profited about $912,000 from the protocol governance entity 42DAO.
