Security Now

What happens when a 27-year-old gets handed the keys to completely refactor nearly all of Cisco's code? This week's episode dives into tech's strangest management bets and the friction brewing inside one of the industry's giants.

• Cisco gives a 27-year old the task of recoding 98% of their software with AI.
• A serious but not earth shaking vulnerability found in PXE booting.
• The largest ($6.3 BILLION) financial heist in history (with crypto).
• 710 Polymarket gambling wallets emptied of $2.7 million.
• A new robots.txt control for AI bots, and agreement to obey it.
• Google generates haiku from the first orbital AI.
• From our listeners: Does stealth updating make sense, how to move web servers off the Internet, books don't contain knowledge, a small company attacked by powerful AI, how would an "AI kill switch" be implemented.
• Another new and worrisome application of reverse-engineering AI

A newly uncovered PHP vulnerability put nearly 70% of the internet at risk, sending governments and enterprises into a frenzy as AI-powered attackers raced to exploit a flaw that had lurked unnoticed for 14 years. Hear why this could be just the start of an unrelenting wave of security crises.

• We take a detailed look at the many facets and aspects of last week's wild PHP ride:
• What happened.
• How it happened.
• Why it happened.
• How it could have been prevented.
• How it impacted many of our listeners.
• We consider the implications of what is said to be coming next and the idea of temporary "strategic disconnection" from the Internet
