Symbiosis bridge exploit: attacker mints 46.1 billion unbacked syBTC
- —The attacker deposited 330 satoshi (~$0.25) and minted 46.1 billion syBTC
- —12 fake deposits in 4 minutes through BNB Chain, Ethereum and Rootstock
- —Before the attack, the syBTC supply was only 13.91 coins
- —Damage to LPs and users is 9.97 BTC, about $770,000
Why it matters: It highlights cross-chain bridges' vulnerability to combined bugs and the risk of losing funds in syBTC liquidity pools.
