Interview with Jon Hladik - ChatMate
Imagine a user asks an LLM a question about a document. An attacker then gains an interactive prompt on the user’s chat session, enabling the attacker to instruct the AI assistant to take actions on behalf of the victim. That is exactly the capability researchers at Rubrik Zero Labs were able to demonstrate in a recent study designed to test the bounds of LLM security.Join Joe Hladik, Head of Rubrik Zero Labs, as he breaks down the discovery of "Remote Prompt Execution," a novel vulnerability class that enabled full takeovers of Microsoft Copilot sessions through sandbox escapes. He explores the technical journey behind the eight critical CVEs uncovered by Rubrik Zero Labs and discusses the broader implications for securing generative AI assistants within enterprise environments. This interview highlights the groundbreaking research that earned a $48,000 bounty and featured as a premier briefing at Black Hat USA.Segment Resources:- Find more research from Rubrik Zero Labs

Topic Segment - AI Notetakers and Recorders
AI notetakers are built into everything now, and hardware-based AI recorders are becoming mainstream as well. Is privacy over in the workplace? Adrian, Jackie, Katie, and Tyler discuss.Questions enterprises should be asking:- Are employees recording or transcribing meetings?
- Does this policy change if non-employees (external parties) are present?
- Is consent asked for/given?
- Is the context of the conversation taken into consideration?
- Is the geographic/legal/political context of the external party taken into account?
- Have you done your due diligence on third parties hosting/storing these recordings and transcriptions?
- Was your due diligence a SOC 2, or real, actual evidence-based due diligence?
- Do these third parties have an option to allow you to store/manage your own recordings in a place of your choosing, or does it have to be hosted by the AI recording/transcription company?

As the Head of Zero Labs at Rubrik, he is dedicated to uncovering emerging cyber threats, analyzing attacker methodologies, and translating complex security challenges into actionable insights. His work focuses on strengthening organizational defenses against modern cyber risks, particularly in data security and cloud-based threat landscapes.
- If you’ve invested in threat intel and still can’t tie it to real risk reduction, you’re not alone. A lot of programs are collecting intel, but not operationalizing it across detection, response, or the business.So what’s actually working?At the Threat Intelligence Virtual Cybersecurity Summit on August 26th, you’ll hear how mature teams are turning intel into action and making it measurable.Security Weekly listeners can register for free at https://securityweekly.com/threatintel using the promo code: CSS26-SW

- CYBERCRIME: WA man set up fake free wifi at Australian airports and on flights to steal people’s data, police allege
Over 7 years for hacking Wi-Fi, but this guy was prolific - this is not a single incident like the DEF CON dunce coming home via a Delta flight inbound to Atlanta.
- BREACHES: tl;dv (Too Lazy; Didn’t Validate): 181,874 Meetings Left Wide Open
This is basically a supply chain incident. If you had a meeting with someone using tl;dv (e.g. a vendor's sales team), you might be recorded in the leaked files/videos.
- BREACHES: The Hugging Face hack is a PR crisis that’s costing OpenAI millions
Easily the most talked about incident at Black Hat and DEF CON. Black Hat gave the stage to two OpenAI engineers to go into more details about how their agent did crimes. The confession was recorded and published on YouTube.
The biggest question still seems to be, "this can't be legal, right?"
Especially as Anthropic, Meta, and others have confessed in quick succession after OpenAI's admission.
Admitting to sandbox escapes instantly turned into a meme, which was fun.
- RESEARCH: Why AI-generated vulnerability patches still require expert human review
Hands down, the most interesting research I saw at Black Hat, BSLV & DEF CON. Friend and past host at Security Weekly, Keith Hoodlet now leads the research team at 1Password's new independent lab, Off-by-1.
Their first research aims to determine how good AI is at creating patches for vulnerabilities. This research couldn't come soon enough, as the Cloud Security Alliance and many vendors are telling practitioners that letting AI code the patches is the only way to keep up with the massive influx of AI-discovered vulnerabilities.
I published my own take on the research on my Substack.
- RESEARCH: After the Shell: What Attackers Do After They Land a Shell at the Internet’s Edge
This report goes along with a new product called "Tactics" from GreyNoise. A few months ago, GreyNoise made it possible for customers (even at the free tier) to deploy their own honeypot sensors for data collection. The idea is that you can put it near your network, or at the edge, to get more information about attacks targeting you. You can make the sensors look like all sorts of different devices, much like a Thinkst Canary, though this is for data collection and analysis, not attack detection.
Tactics takes it a step further, turning the sensor into a high-interaction honeypot, giving you insight into what attackers are doing after they successfully hack something.
The report details some of what they've found. Super useful for defensive strategy.

- RESEARCH: Largest AI Supply Chain Breach of 2026: LiteLLM Hack Impacts Thousands of Global Enterprises – Claim Your Ethical Disclosure
The cascading breach that Trivy started continues! LiteLLM was compromised as a result of Trivy, and a LOT of organizations were apparently using LiteLLM. Now, a ~150GB archive of data and cloud credentials stolen from LiteLLM has been spotted.
This is one of those situations where there's so much leaked data, it almost helps the victims, because it's impossible for attackers to target them all (maybe?)
