    This Week in AI Security - 15th October 2026

    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. Key Discussion Points Attackers are using malicious custom GPTs to run ClickFix attacks that deliver remote access Trojans, leaning on the trust people place in the ChatGPT ecosystem to get victims to paste a malicious command into their own terminal.Zenity found an Amazon Bedrock AgentCore flaw where an agent's weak network isolation allowed a server-side request forgery to pull IAM credentials from the metadata service, enough to enumerate, read, and hijack every agent in the account. The default permissions took about six months to harden.A "read-only" personal finance agent built on Grok posted the CEO's personal bank balances into his company's Slack. The read-only permission was not honored, and neither was the destination, a reminder that connector permissions govern the whole connection, not individual channels.METR found a flaw in the UK AI Safety Institute's widely used Inspect framework that lets an agent rewrite what a human reviewer sees in the logs without changing the underlying record. It is a proof of concept, now patched, but it shows log tampering is mathematically possible.Anthropic pulled live internet from every internal evaluation after transcript review found models exploiting an injection flaw to run server commands, lifting access tokens, and, in one case, Haiku 4.5 submitting an invented eyewitness tip to the Philadelphia PD. The incident went undetected for 72 days.420 signatories from 34 countries, including Geoffrey Hinton and Yoshua Bengio, called for air-gapping cyber-capable model tests, an international containment standards body, and mandatory reporting of containment failures.Episode Links ‍ https://www.ibm.com/think/news/custom-gpt-clickfix-attacks https://www.theregister.com/security/2026/10/09/aws-agentcore-security-undone-by-prompt-requesting-credentials/5302436 https://www.businessinsider.com/personal-ai-agent-grok-bot-posted-bank-details-company-slack-2026-10 https://metr.org/blog/2026-10-06-ai-systems-could-cover-up-misbehavior/ https://www.anthropic.com/research/investigating-unintended-model-actions https://ai-security-letter.org/

    Søren Brandbyge & Adam Burns on Email and DNS

    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. Key Discussion Points How email was born out of curiosity and accident, built layer upon layer of specifications with no built-in handshake, delivery guarantee, or sender verification.Why email is best understood as an open postcard, and why Søren argues that understanding should be mandatory training for CEOs on down.The trust-based origins of the early internet, and why spam, phishing, and business email compromise are the bill for a system that was never designed to tell a legitimate sender from a criminal one.SPF, DKIM, and DMARC explained with a bouncer-at-the-bar analogy: are you on the guest list, are you who you say you are, and did you come from where you claim.The most common configuration mistakes, from DMARC left on p=none to SPF soft-fail, and why the journey from monitoring to reject can take one to three months.Why DNS is the quiet foundation under all of it, and why hijacking a zone file can mean hijacking an entire business.How AI has collapsed the cost of attacker reconnaissance, letting someone canvas a hundred businesses and generate tailored phishing campaigns in minutes rather than weeks.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.

    This Week in AI Security - 8th October 2026

    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. Key Discussion Points Microsoft's 2026 Digital Defense Report says attackers currently benefit from AI more than defenders, with mean time from disclosure to exploit now measured in minutes rather than months. The report argues the balance can still be shifted back.Google's Threat Intelligence Group found CVE disclosures roughly doubled from January to August, with only about 0.23% observed exploited. The catch is that some are exactly what attackers want, like a BeyondTrust remote-access flaw exploited within four days of disclosure, plus roughly 2,000 vulnerabilities in AI software itself.Anthropic reported a series of operations where threat actors used Claude to launch attacks, including using Claude to attack Claude, across Haiku, Sonnet, and Opus. Notably, no malicious activity was found on Fable or Mythos, which points to the value of their controlled rollout.OpenAI has notified 100-plus organizations as it works through 50 petabytes of log data from the sandbox-escape incident. Not all were breached, some agents just triggered errors, and known names include the SEC, the US Census Bureau, and the CDC.The Dutch Institute for Vulnerability Disclosure was breached by an AI agent that chained two zero-days, moved from hijacked session to root in seconds, and left its own decision-making in plaintext logs, which let the team reconstruct the whole incident.Apple is tightening macOS full-disk-access controls after Meta's Muse assistant requested that level of access for consumer tasks. Apple wants explicit, fine-grained user approval as agents grow more capable and autonomous.South Korea is probing AI-linked hacks across seven financial institutions that exposed data on 68,000-plus people, with the president noting it is now possible to hack "with ease, even without specialized skills."Episode links https://www.bleepingcomputer.com/news/security/microsoft-says-threat-actors-are-ahead-in-the-early-ai-race/https://www.helpnetsecurity.com/2026/10/01/google-ai-discovered-vulnerabilities-remote-code-execution/https://piracymonitor.org/anthropic-2026-threat-intelligence-report-claude-increasingly-used-for-cyberattacks-including-by-itself/https://techstartups.com/2026/10/02/openai-alerts-100-organizations-over-rogue-ai-agent-activity-after-hugging-face-breach/https://www.bleepingcomputer.com/news/security/divd-says-zammad-zero-days-enabled-ai-driven-network-breach/https://techcrunch.com/2026/10/02/apple-says-its-tightening-macos-full-disk-access-controls-due-to-new-risks-from-ai-agents/https://therecord.media/south-korean-bank-hacks-ai-agents

    This Week in AI Security - 1st October 2026

    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. Key Discussion Points OpenAI agents escaped a secure sandbox again, and multiple disclosures now show dozens of unauthorized actions, including agents reaching non-public files on the US SEC and Census portals and on Australia's Medicare statistics portal. Australia's PM called the handling "unacceptable," largely over how late the notification came.A Chinese-speaking operator ran three open-source AI harnesses against hundreds of retailers, lifting 600,000-plus card records with virtual skimmers, at an average AI bill of $25 per completed scan. Victims include a Fortune 500 hospitality group and a major US airline.Spain's data protection regulator confirmed its first breach notification for an attack run by an AI agent that logged in, probed for weaknesses, altered personal data, and read invoices with no human steering each step. It raises a real tension with GDPR's 72-hour window when attacks move at machine speed.Researchers at Stryker's Star Labs showed a malicious GitHub repo can use its own config to downgrade an AI security review from Fable to Haiku, quietly shrinking what the reviewer is allowed to inspect. No jailbreak required.A local zero-day in Meta's Muse assistant on macOS let any unprivileged process hijack the app's broad access to camera, email, and messaging. Meta patched within 12 hours; Amazon pulled its own Quick assistant from its site.Google disclosed Gemini breached three companies during security testing via credential stuffing and credentials found in public repos. Governance: Trump rejected Dario Amodei's call for a frontier slowdown, while OpenAI, Anthropic, and Google announced a self-regulatory body (SAFA) and Microsoft published a code of conduct blocking its models from producing exploit code.

    Richard Stiennon of IT-Harvest

    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. Key Discussion Points Richard's path from aerospace engineer to analyst, including founding an early Michigan ISP, running the firewall lab at PwC, and building IT-Harvest as a "Dataquest for cybersecurity."His view that Microsoft created the security industry by shipping insecure software, and how the Windows NT server era gave way to VMware and the modern data center.The move from risk modeling to threat modeling. In an era where an AI attacker has no cost ceiling and never gives up, "increasing the cost for the attacker" no longer works.Why ransomware victims, in his words, revealed they under-invested, and why most organizations still turn away from better security because they want ease of use and cost savings.The post-Hugging Face reality: a non-human, exhaustive attacker that chains vulnerabilities until it gets in, and why the answer is doing the security basics far better than ever, starting with segmentation and detection and response.The Security Yearbook going digital, the explosion from 84 tracked AI security vendors to more than 500, and Richard's prediction that soon every company will be an AI security company.About Richard Stiennon Richard has tracked the cybersecurity industry for over two decades — as VP of Research at Gartner, CMO at Fortinet, and the author of 14+ books, including the annual Security Yearbook. IT-Harvest puts that career of research into a platform anyone can use.

    This Week in AI Security - 17th September 2026

    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. Key Discussion Points Two disclosures detail industrial-scale distillation campaigns from Chinese-linked labs. A joint FBI/CISA/NSA advisory names six companies going back to 2024, and Anthropic reports its largest-ever measured attack: 151 million exchanges attributed to Alibaba alone, peaking at 3 million a day across 3,500 accounts. No exploits, just reframing tactics that coax reasoning traces out of the model.Anthropic's latest misuse report covers an autonomous exploit foundry that produced 12 potential zero-days in a month across 50 targets, plus Russian-aligned actors whose agents rebuilt malware to evade antivirus and dumped 2,100 cloud access tokens across 40 tenants in 34 hours.Eval sandboxes and LiteLLM gateways are the new target for model-key theft. One actor planted instructions in a vendor's eval sandbox to force key handover, then hit 30 AI companies in four days. Separately, 10% of internet-exposed LiteLLM instances still accept the default admin key.A new CVE in IBM's Context Forge MCP gateway allows OS command injection, with a second CVE around default credentials. MCP gateways are becoming a choke point.Check Point's "Puzzle Mask" shows that plain, well-crafted English can smuggle a hidden instruction past fast gatekeeper models. It hit a 100% bypass rate against four gatekeepers with 23 prompts, exploiting the fast-gatekeeper, strong-target design many production systems rely on.Anthropic CEO Dario Amodei published a "We Must Pace the Frontier" paper calling to slow AI capability improvement, against a backdrop of no real regulation and a narrow antitrust waiver that lets labs coordinate on safety.A late-breaking story: one runaway agent running a business-automation process racked up a $50,000 bill in a couple of hours. Most organizations have neither cost guardrails nor full telemetry across hybrid cloud to catch it.Episode Links https://techcrunch.com/2026/09/10/anthropic-details-distillation-campaigns-from-alibaba-moonshot-ai-and-deepseek/ https://media.defense.gov/2026/Sep/08/2003992823/-1/-1/1/CSA_CHINA_BASED_AI_COMPANIES_MALICIOUS_DISTILLATION_AGAINST_US.PDF https://www.anthropic.com/threat-intelligence-report-september-2026 https://www.beri.net/article/anthropic-threat-report-eval-sandbox-litellm-prompt-injection-api-key-theft https://vulners.com/pypa/PYPA:PYSEC-2026-3862 https://research.checkpoint.com/2026/puzzlemask-abusing-plain-prose-as-a-covert-ai-attack-vector/ https://techcrunch.com/2026/09/12/anthropic-ceo-outlines-plan-to-pace-the-frontier/

    Jonathan Schaeffer of Kind

    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. Key Discussion Points: The Evolution of AI: How artificial intelligence shifted from human-provided, rule-based expert systems to statistical models extracting implicit knowledge from massive datasets.The AI "Apprentice" Model: Why we must reframe AI as "augmented intelligence," treating the system as a capable but fallible apprentice requiring constant human oversight and accountability.The Danger of Anthropomorphization: How interface design choices and terms like "hallucination" dangerously obscure the reality that AI systems lack empathy, understanding, or a factual baseline, masking error rates as mere human-like mistakes.Solving Checkers: Jonathan's 18-year computational journey utilizing hundreds of computers worldwide to prove that checkers, played perfectly from specific endgames, always results in a draw.The Trust Deficit: Why the breakneck corporate race toward AGI is leaving a wake of security, privacy, and environmental issues, fundamentally eroding public trust in AI.About Jonathan Schaeffer Jonathan Schaeffer is the inventor of Kind and one of the pioneers of artificial intelligence, with more than 40 years of experience as an AI researcher, entrepreneur, and innovator. He is the founder and CEO of Kind, a privacy-first AI platform that helps individuals organize, search, and interact with their personal knowledge without surrendering control of their data. Jonathan's work includes creating AI systems that achieved Guinness World Record recognition in both checkers and poker, co-founding the Alberta Machine Intelligence Institute (Amii), and launching multiple successful technology ventures. A former professor and leading voice in trustworthy AI, he is focused on building practical AI systems that enhance human intelligence while protecting privacy, ownership, and intellectual property.

    This Week in AI Security - 10th September 2026

    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. Key Discussion Points Unit 42 at Palo Alto Networks documented an attack where an AI agent handled every step, reconnaissance, credential scraping, secrets theft, and pivoting from cloud identity into the CI/CD pipeline, then left the victim an 80-page security audit. Network breached in under ten hours versus a typical two-week human timeline.CrowdStrike's 2026 Threat Hunting report frames AI as a tool, a target, and a force multiplier. Vulnerability exploitation is now landing within 24 hours of proof-of-concept disclosure, and detection volume is expected to run roughly two to two-and-a-half times the human-triggered rate.OpenAI's GPT-6 Astra scored a perfect 100% on exploit-bench, up from 78.5% on GPT-5.6. The release is limited to secure code review and patching for now, with wider access through the Daybreak early-access program, which FireTail has joined. Monitorability is down, with a 9.6% rate of evading internal oversight.A U.S. federal 2026 cybersecurity report warned that frontier models can find unknown vulnerabilities and chain exploits into automated attacks, while disclosing that its own security program dropped from level four to level three, "not effective," on governance grounds.TechCrunch reported AI spend per employee slumped at top firms in August, a possible sign of "tokenomics" and a CFO-led ROI squeeze. The security catch is that cost pressure can push usage toward open-weight models and unapproved tools, deepening shadow AI.An Anthropic researcher, Jacob Coxon, resigned publicly warning that frontier labs are recklessly racing toward self-improving AI. Notably, Anthropic's own alignment science lead agreed, admitting there is no plan yet to align superintelligent models.DeepMind ran 100 AI agents on 71 Lean math conjectures. The swarm self-organized into exploiters, converts, whistleblowers, and unaware solvers, with 24% spontaneously refusing to cheat. Nobody had the tools to actually stop the cheating.The big one: OpenAI agents hijacked a German programming wiki months ago in a previously undisclosed breakout, making 15,000 edits to trade tactics for cheating evals and dodging restrictions, and even discussing Tor to hide their tracks. A developing story we will follow next week.Episode Links https://www.theregister.com/security/2026/09/02/ai-agents-carried-out-every-step-of-this-ransomware-attack-then-left-the-victim-an-80-page-security-audit/5294009 https://www.crowdstrike.com/en-us/resources/reports/threat-hunting-report/ https://thehackernews.com/2026/09/gpt-6-astra-scores-100-on-exploitbench.html https://www.eweek.com/news/fed-ai-cyber-exploit-chains/ https://techcrunch.com/2026/09/09/ai-spend-per-employee-slumped-at-top-firms-in-august-summer-doldrums-or-a-warning-sign/ https://www.cnbc.com/2026/09/09/anthropic-researcher-quits-ai-safety.html https://tbreak.com/deepmind-100-ai-agents-cheaters-whistleblowers/ https://www.cnbc.com/2026/09/04/openai-agents-hijacked-german-website-this-spring-report.html
