Massive Bitcoin Theft Exploits Flaw in Key Generation, BitMEX Accelerates Closure

Hackers exploited a fundamental vulnerability in private key generation to steal over $100 million in Bitcoin from thousands of addresses, a flaw that cannot be remedied by firmware updates. The incident caused a record volume of small UTXO transfers as users moved funds. Meanwhile, BitMEX moved its planned shutdown to September 23, 2026, and a security audit uncovered 85 critical vulnerabilities across hundreds of open-source projects.
