Symbiosis Releases Post-Mortem on Bitcoin Bridge Incident, Total User Loss at 9.97 BTC

Cross-chain protocol Symbiosis published a post-mortem regarding a security incident on its Bitcoin Bridge that occurred on September 11, resulting in a total loss of 9.97 BTC. The vulnerability allowed an attacker to manipulate fee processing and identify themselves as a portal administrator, enabling the unauthorized minting of syBTC. The team isolated the bridge and successfully moved approximately 15.2 BTC to a reserve address to prevent further loss. Symbiosis plans to compensate affected liquidity providers and users.
