Episode Overview

Theme:
This special bonus episode of "The Rest Is Classified," hosted by Gordon Corera in Google's London HQ, offers an insider look at the intersection of big tech, cybersecurity, and global affairs. The featured guest is Kent Walker, President of Global Affairs at Alphabet (Google's parent company). The conversation delves into Google's response to major cyber attacks, particularly Operation Aurora, the evolution of cyber defense, the company’s fraught relationship with China, and reflections on the early days of hacking.

Key Discussion Points and Insights

1. Operation Aurora: A Defining Moment for Google

Timestamps: 01:31 – 03:25

• Google’s Reaction:
  Kent Walker recounts the intensity of the response to Operation Aurora, the major China-linked breach in 2009-2010.

  • Quote:
    “We went on 24/7 round the clock focus on this... Senior management was there, Sergey Brin, others were very focused on understanding this in a deep way. And it also then set the framework for a lot of our cybersecurity work for the decade to come.”
    — Kent Walker, [01:36]

• Long-term Impact:
  Aurora catalyzed a transformation in Google’s approach to cybersecurity, emphasizing a shift from traditional perimeter defenses (“crunchy on the outside, chewy in the middle”) to layered, “zero trust” models.

  • Quote:
    “Even in an open environment like the Internet, you can still have defense in depth. You can have what's called zero trust... you have to validate who you are at every step of the process.”
    — Kent Walker, [02:42]

2. The Bold Decision to Go Public About Being Hacked

Timestamps: 03:25 – 04:21

• Breaking Industry Norms:
  Google was among the first major tech companies to publicly acknowledge a breach and attribute it to nation-state actors, a move rarely seen at that time.

  • Quote:
    “One of the challenges we had was getting companies to go public... Security is a team sport; we're all only as secure as the least secure vendor or the person in your ecosystem.”
    — Kent Walker, [03:37]

• Industry-Wide Alert:
  Google’s disclosure helped alert scores of other companies involved in the same campaign.

3. Pulling Out of China: The Aftermath of Aurora

Timestamps: 04:21 – 04:52

• China Exit Decision:
  The combination of cyber intrusions and censorship issues led to Google relocating its consumer services outside the Chinese firewall, fundamentally altering its presence in the Chinese market.
  • Quote:
    “We had for years been engaged with China and had made the decision ultimately as a result of this, to move our consumer oriented products outside of the Chinese firewall.”
    — Kent Walker, [04:24]
  • Continued Business:
    Google’s advertising business continues in China, but its major services remain closed off to Chinese consumers.

4. Kent Walker’s Early Career and the Birth of Cybersecurity

Timestamps: 04:52 – 06:38

• Tech-Crime Prosecution:
  As a former federal prosecutor in Silicon Valley, Walker helped launch one of the earliest U.S. High Tech Crime Task Forces in the 1980s-90s, focusing on cases ranging from floppy disk piracy to high-profile hackers like Kevin Mitnick.

  • Quote:
    “Even the sound comes across as, you know, 1980s, 1990s vintage. We were at that time looking at things like the hacking of software, which was back on disks, or in the counterfeiting of some of these materials.”
    — Kent Walker, [04:58]

• The Early Hacker Era:
  Anecdotes include exploits by Kevin Mitnick, the notorious phone phreaks, and the famous incident that crashed "America’s Most Wanted" tip hotline:

  • “When they did an episode about Kevin Mitnick, for the first and only time in the history of the show, the toll free line went dead for three hours.” — Kent Walker, [06:27]

• Move from Playful Mischief to Real Crime:
  The conversation draws a line from the technically clever, often mischievous early exploits to the more serious criminal and privacy-violating hacks of today.
