The cross chain protocol Symbiosis Bitcoin Bridge has a vulnerability, allowing attackers to mint approximately $46.1 billion worth of syBTC and cash out $336000 by selling 4.39 WBTCs on Ethereum's Uniswap V4. The attack occurred at 12:28 am on September 11th (UTC+8), and the team has suspended BTC routing and recovered 15 bitcoins to deposit into a multi signature wallet. At the same time, they have offered the attacker a 20% white hat bounty, with a deadline of September 13th. (Source: Bitcoin.com News)
