Symbiosis Bitcoin Bridge Exploit Results in Billions of Unbacked syBTC
- A hacker exploited Symbiosis’s Bitcoin bridge, minting billions in unbacked synthetic BTC.
- The attacker managed to convert a small portion into approximately $336,000 worth of real wrapped bitcoin (WBTC).
- Symbiosis recovered about 15 BTC and offered a white-hat bounty of 20% of the funds for information leading to recovery.
- The deadline for the bounty offer was set for September 13, with no confirmation yet on its acceptance by the attacker.
- Similar security breaches have affected Liquid and Nomic recently, involving unbacked asset creation.
This incident highlights vulnerabilities in cryptocurrency bridges that allow hackers to create unbacked assets, as seen with Symbiosis’s recent exploit where billions in synthetic BTC were minted fraudulently. The company is actively seeking to recover more funds through a bounty offer.
Symbiosis has already recovered some losses but continues efforts to reclaim more funds by incentivizing information on the hack before their set deadline. (Source)
