Overview

This episode dives deep into the discovery and analysis of FAST-16, a sophisticated cyber weapon from the mid-2000s that may have sabotaged Iran's nuclear program by corrupting complex mathematical calculations. Security researcher Jags (Juan Andres Guerrero Saade) spent years reverse-engineering this mysterious malware, ultimately revealing an 'epistemological warfare' operation that drove nuclear scientists to question their own reality by making 2+2=5 in their critical simulations.

The Discovery of FAST-16: A Cryptic Clue

Cybersecurity researcher Jags discovered FAST-16 on a leaked NSA list of malware, where it stood out with the bizarre instruction 'nothing to see here, carry on.' This cryptic message was like catnip to a cyber-paleontologist, suggesting something extraordinarily secretive. Despite intense effort, Jags couldn't crack the mystery initially and was so consumed by it that he tattooed 'FAST-16' and 'nothing to see here' on his arm as a permanent reminder of the unsolved puzzle.

  • FAST-16 appeared on a leaked NSA malware list with the unique instruction 'nothing to see here, carry on'
  • The cryptic instruction was completely different from all other entries, which typically said things like 'seek help' or 'pull back'
  • Jags worked 'cracked out nights' trying to reverse engineer it but couldn't solve it initially
  • He tattooed 'FAST-16' and 'nothing to see here' on his arm as a reminder of the unsolved mystery
" There's one, just one line that's like completely different to all the other ones. And it just says FAST-16, nothing to see here, carry on. In all caps. That's it. "
" I have built a home in the Valley of Despair. I'm in the process of gentrifying the Valley of Despair, if any of you would like to join me there. "

Stuxnet: The Mother of Cyber Sabotage

Before diving deeper into FAST-16, the episode explains Stuxnet, the groundbreaking cyber weapon that allegedly destroyed a fifth of Iran's nuclear centrifuges in the mid-2000s. Stuxnet was revolutionary because it proved cyber weapons could destroy physical infrastructure while making everything appear normal on computer screens. This discovery essentially birthed the modern cybersecurity industry and revealed that sophisticated cyber warfare had been happening for years without anyone knowing.

  • Before Stuxnet, cyber espionage was discussed only as a theoretical possibility at security conferences
  • Stuxnet spread through Iran's uranium enrichment network and made centrifuges malfunction while displaying normal readings
  • The malware destroyed approximately 20% of Iran's centrifuges and likely slowed their nuclear program
  • Stuxnet revealed that sophisticated cyber warfare had been happening at a massive scale for years
" The operators are hearing that these things are like making these weird noises. They're spinning up. They sound like it sounds like things aren't going well in this room next door. But I'm looking at the computer and the computer tells me everything's normal. "
