Stuxnet showed how cyber attacks can manipulate physical processes and cause real-world damage, yet many critical lessons remain unaddressed. Offensive cyber tools are more advanced than publicly visible, with governments continuing to build capabilities in secrecy. Since Stuxnet, major incidents such as the German steel mill attack, attempts to disable safety systems in Ukraine and the Middle East, and the Colonial Pipeline ransomware event have proven that cyber operations can shut down vital infrastructure and cause large-scale economic and societal disruption. Claims that the impacts of such attacks were minimal are contradicted by these events, which demonstrated both direct physical damage and cascading effects on millions of people.

Protection of critical infrastructure has not advanced at the same pace as threats. Government strategies often underestimate industrial risks, focusing instead on consumer technologies, while meaningful international cooperation on cyber norms has stalled. Standards like ISA 62443 offer strong technical guidance but suffer from organizational and accessibility issues. States continue to view cyber operations as cheap, deniable, and effective tools, unconcerned about collateral damage. The result is a post-Stuxnet world where societies are increasingly dependent on fragile, interconnected systems that remain vulnerable to both deliberate attacks and unintended failures, while warnings go unheeded.
