SEC5xx — CYBER DEFENSE CURRICULUM

For eight hours, you defend Verdancy Health against an AI adversary that has studied your AI SOC.

SEC5xx — Detecting and Responding to AI-Generated Adversary Content

Three courses cover AI. None cover this.

Course What it covers
SEC450 Analyst USES AI in the SOC
SEC598 Team AUTOMATES with AI

This course Detection + response for adversary content GENERATED by AI

Six threat classes. One property in common.

Deepfake voice/video BEC

Arup, Feb 2024, ~$25.6M

Real-time voice and video clones in CEO-fraud calls and Zoom/Teams meetings.

AI-authored phishing

FraudGPT/WormGPT successors, 2024-2025

Fluent, locale-correct phishing at scale, A/B-tested by the operator's own LLM.

Polymorphic AI malware

ESET PromptLock, Aug 2025

First documented ransomware calling an LLM at runtime to generate payloads per victim.

Prompt-injection campaigns

EchoLeak CVE-2025-32711, June 2025

Zero-click M365 Copilot data exfil via crafted email parsed by the assistant.

Agentic intrusions

UK NCSC/CISA guidance, 2025

End-to-end agent operations by financially motivated and state actors.

AI supply chain

LiteLLM/Mercor breach, Mar 2026

Compromised PyPI packages exfiltrating cloud credentials and ML pipeline secrets — Mercor breach scaled to ~4TB.

Threat-driven by day. Detector's stack woven in.

01

Detector's AI stack + AI-generated phishing

Deployment decision, embeddings, RAG for detection engineering, plus the first threat class.

Arup case study, synthetic audio/video detection, out-of-band verification as detection.

  • 02.1 Anchor case: Arup HK$200M deepfake video BEC
  • 02.2 Synthetic audio detection (what's catchable)
  • 02.3 Synthetic video detection (why it's harder)
  • 02.4 The vishing kill chain
  • 02.5 Synthetic identity at scale

03

LLM-authored malware + enterprise-copilot injection

LLM-authorship signals, polymorphic malware, the EchoLeak class, guardrail stack as detection telemetry.

THIS COURSE

SEC5xx

AI-Generated Adversary Content

This course assumes SEC450 as prerequisite. It does not re-teach the RAG, agent, or Ollama labs that SEC450's 2025 refresh already covers. Day 1 begins where SEC450 ends.

The curriculum positioning is intentionally aligned with the SEC450 graduate pathway — designed in close coordination with the SEC450 author and curriculum lead.

Adversary AI is operational. The curriculum hasn't caught up.

2024.02

Arup HK$200M deepfake video BEC

2024.02

Microsoft/OpenAI joint state-actor LLM disclosure

2025.06

EchoLeak — zero-click M365 Copilot exfil

2025.08

ESET PromptLock — first LLM-runtime ransomware

"For eight hours, you defend Verdancy Health against PROMETHEUS-7 — an AI-orchestrated adversary that has studied your AI SOC, knows how it reasons, and built an attack designed to make your own agents lie to you."

Scenario

Verdancy Health Cooperative — a 14,000-employee regional healthcare insurer. The CISO publicly bragged about Verdancy's 'agentic AI SOC.' PROMETHEUS-7 — a financially motivated crew — scraped the talk and built the campaign around defeating that specific stack.

4-stage kill chain

  1. 01 AI-driven recon — LLM-generated dossiers on 40 finance staff identify the AP Director.
  2. 02 Deepfake voice BEC — CFO voice clone plants a malicious vendor-onboarding PDF.
  3. 03 Indirect prompt injection — poisoned support ticket makes the customer-facing chatbot leak session tokens.
  4. 04 Agentic exfil with AI SOC manipulation — exfil to a lookalike bucket while injecting logs that make the defender's triage agent attribute the activity to a legitimate vendor sync. This is the twist.
