  "account": "Cross-chain liquidity protocol Symbiosis announced on Friday that it had recovered 15 Bitcoin, valued at approximately $1.1 million, from a bridge exploit. The attacker, however, refused to return the stolen funds, leading Symbiosis to offer a 20% bounty for information leading to asset recovery. The protocol had initially proposed a 20% white-hat bounty, but the deadline for the offer expired on Sunday. Symbiosis clarified that all routes remained operational, with the exploit affecting its native Bitcoin bridge, which is currently paused. The attacker managed to mint 46.1 billion unbacked tokens from the protocol's Bitcoin bridge, eventually netting 4.3 Wrapped Bitcoin (WBTC), worth $336,000. Symbiosis is currently determining the relationship between the recovered Bitcoin and the $336,000 in proceeds attributed to the attacker. The protocol has yet to disclose its final accounting of losses incurred.",
