Current outcome

A Hacker News user posted a reconstructed source code of the Stuxnet malware on GitHub, claiming it is for research and educational use only. The project, which runs on Windows XP and Windows 7, reproduces the code of the cyber-weapon that was discovered in 2010. Stuxnet is widely regarded as the world's first digital weapon to cause physical destruction, having reportedly ruined nearly one-fifth of Iran's nuclear centrifuges. Making a reconstructed version accessible supports historical and technical education, but also raises dual-use concerns about enabling attackers to study a real offensive cyber-capability. According to a comment in the discussion, the reconstructed code spans roughly 15,000 lines and is based on the same target as the original Stuxnet: Siemens S7 PLCs and WINCC HMI systems. The repository explicitly states it works only on Windows XP and Windows 7.
