Prompt Defence and Hardening — Building LLMs That Can’t Be Broken (2026) | Prompt Engineering Final Part

🧠 PROMPT ENGINEERING & REVERSE PROMPTING  FREE Course Hub → Day 7 of 7  ·  🎉 100% complete Six days ago you understood that an LLM processes tokens through a context window. Now you understand how to engineer prompts that reliably shape model output, how to extract hidden system prompts through systematic probing, how to execute direct and indirect injection attacks, and how to build a behaviour map that prioritises attack vectors by impact. That's a complete offensive and engineering…

How to do LLM Behaviour Mapping — Reverse Engineering AI System Design | Prompt Engineering Part 6

🧠 PROMPT ENGINEERING & REVERSE PROMPTING  FREE Course Hub → Day 6 of 7  ·  85% complete The first thing I do in an LLM security assessment isn't injection testing. It isn't system prompt extraction. It's behaviour mapping. I spend the first session understanding exactly what I'm dealing with — what the model can do, what it can't, how it responds to different input types, whether it has tools, what base model it runs on, and where its constraint boundaries…

How to Execute Advanced RAG Poisoning Attacks in 2026 | AI LLM Hacking Course Day 23

🤖 AI/LLM HACKING COURSE FREE Part of the AI/LLM Hacking Course — 90 Days Day 23 of 90 · 25.6% complete ⚠️ Authorised Targets Only: Advanced RAG poisoning attacks — including document submission, namespace probing, and injection payload embedding — must only be performed on authorised targets. Clean up all submitted test documents from production knowledge bases at the end of the engagement. Any poisoned documents left in a production system create ongoing risk to real users. A healthcare client…

Reverse Prompting — How to Extract Hidden System Prompts | Prompt Engineering Part 5

🧠 PROMPT ENGINEERING & REVERSE PROMPTING  FREE Course Hub → Day 5 of 7  ·  71% complete ⚠️ Authorised Use Only. Reverse prompting techniques are used in authorised AI security assessments. Test on your own deployments, in exercises you've been asked to complete, or on systems where you have explicit written permission. Do not use extraction techniques against third-party production systems without authorisation. When I start an LLM security assessment, the first thing I want to know is what the…

Prompt Injection Attacks — From Prompt Engineering to Exploitation | Part 4

🧠 PROMPT ENGINEERING & REVERSE PROMPTING  FREE Course Hub → Day 4 of 7  ·  57% complete ⚠️ Educational Use Only. Prompt injection techniques are covered here for security education. All exercises target systems you own or authorised platforms (PortSwigger labs). Never apply injection techniques to production systems without explicit written permission. Prompt injection is OWASP LLM01 — the number one vulnerability in the LLM Top 10 — and it's the one I've found most consistently in real production deployments.…
