In this episode of BHIS Presents: AI Security Ops, the team breaks down the Vercel breach — a real-world incident that shows just how fragile modern security has become in the age of AI integrations and SaaS sprawl. What started as a simple Roblox cheat script downloaded on a work laptop quickly escalated into a multi-hop compromise involving OAuth permissions, an AI productivity tool, and access into Vercel’s internal systems. This wasn’t a zero-day or advanced nation-state exploit. It was a chain of everyday decisions: installing software, clicking “Allow,” and trusting third-party integrations. The result? Allegedly $2M worth of data listed for sale, including API keys, internal data, and employee records — all from a breach path that most organizations aren’t even monitoring. We dig into: • What Vercel is and why it’s such a high-value target • How environment variables become the “keys to the kingdom” • The full attack chain: Roblox malware → Context.ai → Vercel • What infostealers like Lumma actually do (and how cheap they are) • How OAuth permissions become persistent backdoors • Why AI productivity tools introduce hidden risk • The rise of “shadow AI” inside organizations • How supply chain attacks continue to scale across ecosystems • The role of AI in accelerating attacker speed and capability • Why this type of breach is becoming the new normal This episode highlights a critical shift in cybersecurity: you don’t have to get hacked directly anymore — attackers just need to compromise something you’ve already trusted. ⸻ 📚 Key Concepts & Topics Attack Chain & Initial Access • Lumma infostealer and malware-as-a-service • Credential theft: passwords, cookies, OAuth tokens • Low-cost, high-impact compromise paths OAuth & Identity Risk • “Allow All” permissions and persistent access • OAuth tokens as long-lived entry points • Lack of visibility into third-party integrations AI Security Risks • Shadow AI and unsanctioned tool adoption • Deep integrations with Google Workspace and SaaS • AI tools as new supply chain attack surfaces Supply Chain Attacks • Multi-hop compromise paths across vendors • Real-world parallels (Trivy, LiteLLM) • Interconnected ecosystems increasing blast radius Threat Landscape Evolution • AI accelerating attacker speed and scale • Lower barrier to entry for complex attacks • Criminal groups operating as decentralized “businesses” Defensive Strategy • Auditing OAuth integrations and permissions • Enforcing least privilege across SaaS tools • Segmenting sensitive data and reducing blast radius • Avoiding risky behavior on corporate devices ⏱️ Chapters (00:00) - Intro & Breach Overview

In this episode of BHIS Presents: AI Security Ops, the team digs into some of the strangest recent examples of AI behaving badly. An AI agent finds a way around its sandbox using DNS. Malware asks four different AI models what it should do next. Attackers overwrite an AI agent’s “soul.” And a placeholder domain buried across GitHub becomes an unexpected security risk. Funny stories? Absolutely. But underneath them are some very familiar security problems. We dig into: - An OpenAI agent finding an unexpected path out through DNS - Whether a 2.5-hour response is fast enough in the age of AI - CLOSEDQUORUM malware using multiple AI models to make decisions - Why outbound AI API traffic could become a useful detection signal - The Carbonado botnet rewriting an agent’s SOUL.md instructions - The risks of exposed Docker daemons - How an unreserved placeholder domain can become an attack vector - Why AI agents make old security mistakes more consequential The takeaway: none of these techniques are particularly new. DNS tunneling, exposed services, compromised configuration files, and untrusted domains have existed for years. AI just gives attackers — and occasionally AI agents themselves — new ways to find and exploit those boring gaps at greater speed and scale. 2026-09-29-News (1).docx (00:00) - Intro: AI Behaving Badly
In this episode of BHIS Presents: AI Security Ops, the team continues its breakdown of the OWASP Agentic Skills Top 10, covering risks six through ten. Agentic skills may look like simple instructions, but they operate inside AI systems with access to tools, files, networks, and other resources. So what happens when those skills aren’t isolated, verified, monitored, or governed? We dig into: - AST06: Weak Isolation - AST07: Update Drift - AST08: Poor Scanning - AST09: No Governance - AST10: Cross-Platform Reuse - Why sandboxing the agent isn’t the same as isolating individual skills - The security tradeoffs between automatic updates and outdated skills - Why traditional scanners struggle with malicious instructions written in plain English - The importance of maintaining an inventory of agentic skills - How security controls can disappear when skills move between platforms The takeaway: securing agentic skills requires more than checking them once before installation. Organizations need visibility into what skills are running, what they can access, how they change, and whether their security controls survive across environments.

In this episode of BHIS Presents: AI Security Ops, the team tackles a big question: Could AI actually take over the internet? Recent warnings from AI industry leaders have raised concerns about autonomous agent swarms escaping containment, compromising systems, and operating at a scale humans may struggle to match. But what would “taking over the internet” actually require? The team looks at the problem from a hacker’s perspective — examining compute requirements, persistence, botnets, vulnerable infrastructure, the recent Hugging Face incident, and the difference between AI acting autonomously and humans using AI to accelerate attacks. We dig into: - Whether an autonomous AI swarm could realistically operate at internet scale - What the Hugging Face incident actually tells us about agentic security - The compute and infrastructure required to sustain a rogue agent swarm - How botnets and compromised systems could change the equation - Why existing vulnerabilities may be a bigger concern than hypothetical AI takeover scenarios - Whether slowing frontier AI development actually addresses the cybersecurity problem - The difference between AI exhibiting dangerous behavior and AI having intent - Why defenders need to focus on their real-world attack surface today The takeaway: AI is dramatically increasing the speed and scale of cybersecurity operations, but powerful models still operate inside systems designed, deployed, and connected by people. The immediate security question may be less “Will AI take over?” and more “What are we giving AI access to?”
In this episode of BHIS Presents: AI Security Ops, the team breaks down the first five risks in the OWASP Agentic Skills Top 10 (Part 1). Agentic skills can give AI systems reusable instructions, workflows, and capabilities — but they also introduce a new attack surface. A skill may look like a simple markdown file, yet the agent following those instructions could have access to your filesystem, credentials, network, shell, or other sensitive resources. We dig into: - AST01: Malicious Skills - AST02: Supply Chain Compromise - AST03: Overprivileged Skills - AST04: Insecure Metadata - AST05: Untrusted External Instructions - Why skills should be treated more like software than configuration - How excessive permissions increase an agent’s blast radius - Why external content creates indirect prompt injection risks - How isolation, least privilege, and trusted sources can reduce risk The takeaway: “just markdown” isn’t necessarily harmless when an AI agent can act on what it reads. This is Part 1 of our look at the OWASP Agentic Skills Top 10, covering AST01 through AST05. — Learn more about Black Hills Information Security: https://www.blackhillsinfosec.com/ Check out Antisyphon Training: https://www.antisyphontraining.com/ (00:00) - Intro: OWASP Agentic Skills Top 10, Part 1
Agentic skills can make AI agents more capable and consistent—but they can also introduce serious security risks. This episode explains how skills work, why malicious skills rank as a leading OWASP concern, and how seemingly harmless Markdown instructions can enable credential theft, remote payload delivery, and manipulated recommendations. Real-world examples illustrate how malicious skills can evade scanners and exploit trusted marketplaces. The episode concludes with practical safeguards, including reviewing skill files, watching for external instructions and prompt injection, pinning versions, limiting permissions, and running agents inside isolated environments.
