Symbiosis says recovered 15 BTC from bridge hack, offers 20% bounty
Symbiosis is offering a 20% bounty for information leading to asset recovery after the hacker refused to return the stolen funds for the same white-hat bounty.
Cross-chain liquidity protocol Symbiosis said it recovered 15 Bitcoin, worth around $1.1 million, from a Bitcoin bridge exploit it suffered Friday.
Symbiosis said it recovered 15 Bitcoin (BTC) into a team-controlled multi-sig wallet and clarified that all routes remain operational, according to a Friday X post. The exploit affected Symbiosis’ native Bitcoin bridge, which remains paused.
The attacker’s address minted 46.1 billion unbacked tokens from the protocol’s Bitcoin bridge but realized net proceeds of 4.3 Wrapped Bitcoin (WBTC), worth $336,000, according to blockchain security company Blockaid, which flagged the exploit on Friday. The protocol has not specified how the recovered Bitcoin relates to the $336,000 in proceeds attributed to the attacker.
