This episode of Equity explores the recent discovery of two critical, unauthenticated remote code execution vulnerabilities in PHP, collectively dubbed PHP2shell, which impacted roughly seventy percent of the web-facing internet. The guest, Tomer Schwartz, CTO of Exposure Management and AppSec at Wiz, explains how these twelve-year-old bugs were uncovered using AI research tools, why the coordination timeline broke down leading to widespread website shutdowns, and how organizations must adapt to a future of frequent, high-stakes security crises. Throughout the discussion, the host and guest detail the inner workings of automated vulnerability discovery, the pressures of coordinated disclosure, and the imperative for startups to build security into their architecture from day one.
Hosts introduce the episode, sponsor, and set the stage for the discussion.
Tomer Schwartz introduces himself and his involvement in the incident.
Explores the difficulties of coordinated disclosure and the leak that accelerated the timeline.
Tomer explains how AI tools like Atlas helped find and exploit the bug faster.
Wrap-up with contact info, website, and final thanks.
Details how vendors, cloud providers, and WAFs were alerted and monitored for attacks.
Hosts ask about still-unpatched systems and give guidance for small businesses and startups.
Tomer shares his past startups, acquisitions, and advice for cybersecurity founders.
Unauthenticated Remote Code Executiondata
The guest explains that the PHP2shell bugs impacted the last 12 years of PHP deployments, affecting default configurations and roughly seventy percent of the web-facing internet.
Accelerating The Disclosure Timelinestory
Information about the vulnerabilities leaked on social media, forcing researchers to accelerate the patch release schedule before downstream projects had finished building new releases.
Scaling Research With Custom Harnessesstrategy
Wiz uses a custom harness called Project Atlas, which runs on top of frontier AI models from DeepMind, OpenAI, and Anthropic to scale research and test potential attack paths.
Flaws In Coordinated Disclosureinsight
The guest discusses the fundamental flaws of coordinated disclosure, noting that while defenders need time to prepare, the inner circle quickly grows to hundreds of people, making leaks almost inevitable.
AI Enables Complex Exploit Creationinsight
The guest notes that while the PHP bugs were known as problematic areas as early as 2020, no one could build a reliable exploit until AI allowed researchers to scale and uncover these vulnerabilities.
“This is the language behind WordPress, Drupal, Joomla and MediaWiki.”
“We managed to take all of those people and tell them, hey, why wouldn't you try 20 different ideas on various different targets and just run them on top of Atlas and find a ton of different potential vulnerabilities?”
“We want to, want to bring more and more people into the inner circle to make sure that defenders are aware of the vulnerability and they have time to prepare.”
“If a big part of the way that you're doing business relies on trust, I think it makes more and more sense to have that expertise in-house.”
“We had a very concrete plan and a concrete timeline in which we were planning to release the information about the vulnerabilities along with patches.”
The PHP scare may have faded from your feed, but the cleanup is far from over. Last week, two critical bugs in the open source language behind roughly 70% of websites left organizations scrambling to fix their systems, with some taking sites offline until the vulnerabilities could be patched. According to researchers who found the bugs, this is only the beginning, as AI changes how quickly novel vulnerabilities can be uncovered and exploited. On this episode of TechCrunch’s Equity podcast, Rebecca Bellan talks with Tomer Schwartz, CTO of Exposure Management & AppSec at Google-owned Wiz, who was part of the scramble --- alongside OpenAI, research group Calif, and the PHP team --- to fix the bugs. On the show, Schwartz and Bellan get into what the race looked like from the inside, how early-stage startups can build with security in mind, and why patching by hand won’t scale. Listen to the full episode to hear more about: Why Tomer says Wiz couldn’t have found these bugs without AI, and how custom tooling tested dozens of ideas over a weekend. How a bug was able to sit in plain sight for more than a decade, and what changed to make it exploitable. Why leaks are almost baked into coordinated disclosure, and how Wiz planned for it. Who’s still unpatched and whether small business owners running WordPress sites need to worry. Subscribe to Equity on YouTube, Apple Podcasts, Overcast, Spotify, and all the casts.
