## Resource

How did a computer worm get into a supposedly isolated nuclear facility and quietly damage centrifuges without showing its hand? In this episode, we unpack Stuxnet, the infamous cyber weapon that targeted industrial control systems, used USB drives and hidden exploits to sabotage Iran’s nuclear program, and changed cybersecurity forever—listen now, because the line between digital code and physical damage has never been more urgent. Stuxnet was the first widely known cyberweapon to cause real-world physical damage, targeting industrial control systems at Iran’s Natanz uranium-enrichment facility. In this episode, we unpack how a computer worm used USB drives, zero-day exploits, and Siemens SCADA/PLC systems to sabotage centrifuges while hiding its tracks. • How Stuxnet crossed an air-gapped network • Why Siemens Step7 and PLCs were the target • How the worm fed operators false “normal” data • What Stuxnet changed about cybersecurity and critical infrastructure 0:45 — The ordinary USB-drive entry point 3:10 — How Stuxnet found Natanz systems 7:05 — The sabotage logic inside the PLCs 10:20 — Why the worm mattered beyond Iran Related resources and links: Internal: Episode page, transcript, and related cyberwar episodes External: Britannica’s Stuxnet overview, CISA guidance on industrial control systems, U.S. CRS report on cyber conflict If you learned something new, share this episode with a friend and leave a review to help more listeners find it.
