Bitcoin hacking challenge finally falls as researcher proves critical PHP flaw is exploitable

Summary

Researcher Killa breached the Steal My Bitcoin challenge server on October 25 and retrieved its hidden wallet credential, with the operator confirming the result in server logs. The challenge followed disclosure of two critical PHP vulnerabilities, but its initial setup limited access to vulnerable functionality and heavy traffic hindered exploitation. After the operator added an accessible PHP page, the breach followed in under three hours. The researcher published a proof of concept, though gaps remain in the original records. The evidence does not show that an autonomous AI carried out the attack or fully document how AI tools were used.
