Cross-chain protocol Symbiosis says it has clawed back 15 Bitcoin following a bridge exploit, and is now dangling a 20% bounty for information that helps it recover the remaining stolen assets after the attacker declined a white-hat offer.
The Recovery Effort
Symbiosis, a cross-chain liquidity protocol, confirmed it managed to retrieve 15 BTC in the aftermath of the breach that targeted its bridge infrastructure. The recovery marks a partial win for the team as it scrambles to contain the fallout from the attack.
The protocol initially extended a standard white-hat offer to the perpetrator, giving them the chance to return the misappropriated funds in exchange for a bounty and no legal consequences. That approach, common in decentralized finance security incidents, is designed to incentivize attackers to hand back stolen assets rather than launder them.
When the olive branch was refused, Symbiosis flipped the script — now it's paying the community to hunt the hacker down.
Bounty Shifts Targets
After the attacker rejected the white-hat terms, Symbiosis pivoted its strategy. The team is now offering a 20% bounty to anyone who can provide information leading to the recovery of the remaining assets, effectively turning the wider community into investigators.
Bridge exploits remain one of the most persistent threats in the crypto sector, as these tools connect separate blockchains and often hold large pools of locked value, making them attractive targets for attackers.
- Symbiosis recovered 15 BTC from the bridge exploit.
- A white-hat bounty offer was declined by the hacker.
- A 20% bounty is now open for information aiding asset recovery.
Ongoing Risks in DeFi
The incident underscores the ongoing security challenges facing decentralized finance, where cross-chain bridges have repeatedly been the source of some of the industry's largest losses. Protocols increasingly rely on bounty programs and negotiation tactics to recover funds when preventative measures fail.
For Symbiosis, the shift from a cooperative bounty to an information-based reward signals a more aggressive posture as it works to trace the attacker and recoup what remains outstanding.
