Guardian Publishes Deep Dive on Mt. Gox Transaction Malleability Bug
- Centralized Exchange
- Security
The Guardian published a comprehensive technical breakdown explaining how Bitcoin's transaction malleability flaw enabled the Mt. Gox collapse. The article detailed how attackers could alter transaction IDs without sender permission, causing Mt. Gox's flawed accounting to send bitcoins twice. While malleability was a real Bitcoin protocol issue known since 2011, the piece revealed Mt. Gox's stunning lack of proper auditing and security controls—CEO Mark Karpeles allegedly the only person with cold storage access, no customer deposit audits ever conducted. Crypto Twitter erupted with skepticism, with prominent voices like @Falkvinge calling the malleability excuse "impossible" and suggesting an inside job. Published just one day before Mt. Gox filed bankruptcy, the article became the definitive explanation of the exchange's technical and operational failures.
