Blockstream rejects hacker's 10% ransom demand, demands return of remaining 598.5 BTC Regarding the approximately 598.5 BTC remaining after the Liquid Network attack, Blockstream has rejected the hacker's 10% ransom demand and demanded the return of the Bitcoin. 'Unauthorized acquisition of assets and refusal to return them constitutes criminal behavior, not responsible disclosure; this is not white-hat hacking but outright theft.' Previously, the Liquid Network attacker returned 3,400 BTC after Blockstream confirmed the bridge node vulnerability had been fixed, but retained approximately 598.5 BTC (worth around $47.3 million).
