Advanced RAG Security and LLM Security 2026
Course Overview
What You'll Learn
- Advanced Data Poisoning: Hack the ingestion pipeline. Learn how attackers use invisible text (Font-Size 0), Unicode steganography, and metadata injection to poison RAG systems.
- Context Hijacking & Overflow: Exploit the LLM's "U-Shaped Attention" mechanism and execute Context Stuffing attacks that push safety instructions entirely out of the memory window.
- Agentic RAG & SSRF: Watch what happens when RAG pipelines grow hands. Trick AI agents into acting as a "Confused Deputy" to leak cloud credentials or abuse internal APIs.
- The 4-Gate Defense Architecture: Build a bulletproof system. Implement Magic Byte validation, Semantic Chunking, Meta's Prompt Guard, XML Sandboxing, and strict Grounding Evaluators (LLM-as-a-Judge).
About This Free Course
Welcome to the frontline of free artificial intelligence risks in cybersecurity course Security.
The era of simply "slapping an LLM on a database" is over. Retrieval-Augmented Generation (RAG) solved AI hallucinations, but it introduced a massive, highly complex attack surface. When you give an LLM access to internal company documents, vector databases, and API tools (Agentic RAG), you are effectively turning passive data into executable code.
Without proper defenses, a single poisoned PDF or a hidden prompt injection can lead to data exfiltration, Server-Side Request Forgery (SSRF), or a complete system compromise.
In this dense, zero-fluff, 90-minute masterclass, AI Security Researcher Armaan Sidana takes you deep into the trenches of offensive AI security. You won’t just learn high-level theory—you will actively hack Vector Databases, execute context hijacking, and manipulate AI agents. Then, you will learn how to build the ultimate 4-Gate Defense Architecture to lock down your pipelines for production.
What You Will Learn:
Vector Database Exploitation: Discover why default Vector DBs are the soft underbelly of AI. Execute a live heist on a vulnerable Qdrant instance and understand the dangers of Embedding Inversion (turning math back into raw PII).
Advanced Data Poisoning: Hack the ingestion pipeline. Learn how attackers use invisible text (Font-Size 0), Unicode steganography, and metadata injection to poison RAG systems.
Context Hijacking & Overflow: Exploit the LLM's "U-Shaped Attention" mechanism and execute Context Stuffing attacks that push safety instructions entirely out of the memory window.
Agentic RAG & SSRF: Watch what happens when RAG pipelines grow hands. Trick AI agents into acting as a "Confused Deputy" to leak cloud credentials or abuse internal APIs.
The 4-Gate Defense Architecture: Build a bulletproof system. Implement Magic Byte validation, Semantic Chunking, Meta's Prompt Guard, XML Sandboxing, and strict Grounding Evaluators (LLM-as-a-Judge).
Automated Red Teaming: Stop doing manual penetration testing. Learn how to deploy Promptfoo in your CI/CD pipelines, use NVIDIA Garak for deep fuzzing, and orchestrate stateful attacks with Microsoft PyRIT.
Real-World Case Studies & CTF
Learn from the costly mistakes of others. We will deconstruct major real-world failures, including the Air Canada hallucinated policy lawsuit, the Bing "Sydney" prompt leak, and the GitHub Copilot RCE vulnerability.
Finally, put your skills to the test in the Capstone CTF (Capture The Flag), where you will use cross-language translation and context manipulation to break out of a restricted RAG agent and steal an admin password.
Who is this course for?
AI/ML Engineers & Developers building enterprise RAG or Agentic AI applications.
Cybersecurity Professionals & Penetration Testers looking to pivot into the high-demand field of AI Red Teaming.
AppSec Engineers tasked with auditing GenAI systems and ensuring OWASP LLM Top 10 compliance.
Prerequisites:
A basic understanding of Large Language Models (LLMs) and how prompting works.
Familiarity with Python (for following along with defense scripts).
Basic command-line experience (Docker/cURL) if you wish to participate in the local Vector DB hacking labs.
The attacker only needs to bypass one gate once. The defender must secure every gate, every time.
Enroll today and learn how to sanitize the input, restrict the memory, and secure the future of your AI applications.
Who Should Take This Course
"Advanced RAG Security and LLM Security 2026" is aimed at people who want a practical, structured introduction to it without paying full price for it. It's a solid fit if you're starting out in it and want a guided course rather than piecing tutorials together yourself, if you've tried free YouTube content on the topic and want something more organized, or if you already work in a related area and want a refresher you can finish at your own pace. Since enrollment happens on Udemy itself, you keep full access to view the lectures, download any provided resources, and revisit the material later — this isn't a stripped-down or time-limited version of the course.
Why This Course Is Worth Taking
Our take: this listing earns a spot on FreeWebCart because the coupon we verified actually brings the price to $0, not just a token discount, and the course carries a 5/5 rating on Udemy. That combination — real reviews plus a working 100% OFF code — is what we look for before publishing a it course. It won't replace hands-on experience or a full degree program, but as a low-risk way to test whether it is worth pursuing further, or to pick up one specific skill, the free price tag makes it an easy yes while the coupon lasts.
Pros & Cons
👍 Pros
- 100% free to enroll via this coupon (normally $19.99)
