Symbiosis cross-chain protocol attacked on BSC, attacker cashes out ~$336K

The nominal mint dwarfing the realized proceeds is the tell: the exploit was capped not by the contract's limits but by the liquidity available to exit, so the headline figure overstates actual damage while understating how routine these bridge mint-and-dump patterns have become. For wrapped-BTC holders across chains, the takeaway is that a signed receive path on one chain can drain value on another entirely, making cross-chain solvency a shared risk rather than a per-network one. Whether the protocol pauses the affected contracts and how the syBTC supply is reconciled is the open question.
