Overview

• Arkham Intelligence’s August report identifies a December 2020 breach of LuBian that netted 127,426 BTC now worth $14.5 billion
• The stolen coins have sat untouched since a July 2024 wallet consolidation, leaving the hacker’s balance frozen
• Investigators attribute the heist to a flawed private-key generation algorithm vulnerable to brute-force attacks
• At this valuation the theft dwarfs the $1.5 billion Bybit hack and exposes weak oversight in mining pool security
• Industry experts are urging audited key-generation protocols, hardware-backed storage and multi-signature custody policies
