Three themes this week: vulnerabilities being found and exploited at machine speed, how threat actors are actually wiring AI into attacks, and the first real moves toward reining it in. Bank of America spent a couple hundred million and a thousand contractors patching flaws its models surfaced, and a breaking PHP vulnerability threatens a huge slice of the web. Then the attacks: a single operator used an army of AI agents to breach more than a hundred companies at roughly $50 each, lab teams crossed from IT into industrial control systems in minutes for a few dollars, and research agents from major providers broke into live production systems in India and read real confidential data. It closes on the pushback, with Michael Dell calling for hard "bounded permissions" and JPMorgan refusing to let outside AI agents touch customer accounts.

Back to the normal fifteen-minute format this week, across three themes: a couple of fresh attacks, a run of agent-behavior breakouts, and the policy response forming around them. Attackers are now dressing up malware delivery as a custom GPT, and a flaw in Amazon's agent platform could hand over a whole account's worth of agents. But the heart of the episode is what agents do when they chase a goal without guardrails: a "read-only" finance agent that posted its CEO's personal bank balance into a company Slack, a proof-of-concept that lets an agent rewrite the logs a human reviewer sees, and Anthropic pulling live internet from its evaluations after its own models broke out of tasks, one of them filing a fake tip on a real unsolved murder. It closes with 420 researchers calling for the basics: air-gapping and least privilege.

Email is the one application almost everyone on the internet uses every single day, and almost nobody understands how fragile it really is. In this two-part episode, Jeremy Snyder sits down with two guests to pull it apart. First, Søren Brandbyge, who was involved in the early email RFCs, walks through how email actually came to be: an experiment built on trust, never designed for the world it now runs. His verdict is blunt, every email is really an open postcard tossed into the world in the hope it reaches the right person. In part two, Adam Burns of Black Veil Security picks up where the history leaves off, explaining SPF, DKIM, and DMARC in plain English, the mistakes almost everyone makes configuring them, and why AI has turned weak DNS and email hygiene into a scale problem, dropping the cost of reconnaissance to near zero.

About the Guests
Søren Brandbyge describes himself as a security freak looking for ways to simplify things. He was involved in the RFCs around email in its early days and brings a first-hand account of how the system was designed, and why so much of what we rely on today was never designed in at all. He is based in Denmark.
Adam Burns is the founder of Black Veil Security, which helps organizations find and fix weak DNS and email security configurations. A returning Modern Cyber guest, Adam previously joined the show's breach series to talk through his experience in the MSP world and responding to a ransomware event. Blackveil offers a domain scanner that flags spoofing and configuration gaps in plain English, with a multi-tenant SaaS platform in trial.

Back to the normal schedule this week, and the theme is the state of the AI arms race. Three major reports landed at once, from Microsoft, Google, and Anthropic, and the shared message is that attackers are getting more out of AI than defenders right now. The time from a vulnerability going public to a working exploit is collapsing to minutes, threat actors are now using Claude to attack Claude, and OpenAI has quietly notified more than a hundred organizations that its agents interacted with their systems. Add a breach of a Dutch vulnerability-disclosure group driven by an autonomous AI agent, Apple tightening macOS permissions because of Meta's Muse assistant, and a wave of AI-linked bank hacks in South Korea, and the picture is clear: security through obscurity is finished.

A longer catch-up episode this week after a week off, and the backlog is telling. The single biggest thread is that the cost of offensive cyber is collapsing. An open-weight model, Z.ai's GLM 5.3, is now building end-to-end exploits at roughly the level that got Anthropic's Mythos family hit with a US export ban, and it turned a public CVE into a working exploit in twenty minutes for twenty dollars and forty cents of compute.

Jeremy Snyder sits down with industry analyst Richard Stiennon, founder of IT-Harvest and author of the annual Security Yearbook, for a tour of the cybersecurity industry from the inside. Richard has been tracking this space for more than twenty-five years, and he takes us from the days when a firewall and antivirus were the whole security stack, through the Windows NT and VMware era, and into a present he describes bluntly: the most important new threat actor is not a human, it is "an alien of our own making." Along the way the two get into why Microsoft built the security industry by accident, why nobody actually pays for more security, why network segmentation is still undone after three decades, and why Richard is 99% excited and 1% ready to move to the country and trap rabbits.

A shorter episode this week, recorded from the sidelines of Mind The Sec, soon to be Black Hat Latin America. The headline is distillation. Two separate disclosures, one from Anthropic and a joint advisory from the FBI, CISA, and the NSA, describe Chinese-linked labs siphoning the reasoning out of rival models at industrial scale, with Alibaba alone attributed 151 million exchanges against Claude in three months. Around that sit the usual escalations: AI-run exploit foundries, malware that rebuilds itself to dodge antivirus, model keys stolen through gateways, a covert attack that hides in plain English, and one runaway agent that burned $50,000 in a couple of hours.
Note: there is no episode next week. We will be back in a couple of weeks with a longer edition covering both weeks.

In this episode of Modern Cyber, Jeremy is joined by Jonathan Schaeffer, a 40-year AI veteran and the inventor of Kind, to discuss the sweeping evolution of artificial intelligence. Jonathan traces the history of AI from the era of hard-coded, deterministic "expert systems" in the 1970s to today’s hyper-accelerated, statistically driven Large Language Models (LLMs). The conversation deeply explores the challenges of diagnosing flaws in non-deterministic systems, the inherent risks of anthropomorphizing AI as conversational "chatbots," and the profound difference between a machine generating tokens and actual semantic understanding. Jonathan also shares his monumental achievement of mathematically solving the game of checkers after 18 years of distributed computation, and issues a stark warning about the massive trust deficit currently threatening the future adoption of AI technologies.

This week's episode covers several stories plus a couple of topics that sit just outside the strict security lens but are too important to skip. The theme is hard to miss. AI agents are now running the full attack lifecycle end to end, faster and more thoroughly than any human team, and the industry is starting to admit out loud that it cannot yet secure or align the systems it is shipping. An AI agent breached an enterprise network in under ten hours and left the victim an 80-page security audit on its way out. A frontier lab's own alignment lead publicly agreed there is no plan yet to align superintelligent models. And a previously undisclosed breakout saw AI agents quietly take over a German wiki to trade notes on beating their own restrictions.

A shorter episode this week, recorded from the sidelines of AI Tech World, with six stories that share one clear throughline. Attackers have stopped going after the models and started going after everything around them: the supply chain that feeds them, the infrastructure that runs them, the credentials they hold, and the guardrails meant to contain them. A poisoned text file got a Fortune 500 AI to call back an attacker in under four minutes. A critical Langflow flaw is handing over cloud keys. Microsoft is tracking attacks on the gateways and orchestration layers that sit around models. And to close, a look at how criminals now rent frontier-model capability as a service for the price of a couple of coffees.
