The standard prompt injection defences I review — input validation, output filtering, jailbreak detection — all look at the user's message. RAG attacks walk right past them. The attacker never sends the injection through the user input channel at all. They upload a PDF to the shared knowledge base. They submit a support ticket whose content gets indexed. They edit a public wiki page that the enterprise RAG system crawls weekly. Three weeks later, when a legitimate user asks a…

AI Password Cracking 2026 — How Machine Learning Breaks Credentials Faster
The 2023 Home Security Heroes study ran PassGAN against a database of 15.6 million passwords. The results: 51% cracked in under a minute. 65% cracked in under an hour. 81% cracked within a month. PassGAN isn't a traditional dictionary attack — it's a generative adversarial network trained on real leaked passwords that generates novel guesses matching the statistical distribution of how humans actually choose passwords. Those numbers don't mean 81% of all passwords are crackable. They mean 81% of the…

🧪 METASPLOITABLE LAB SERIESFREE Part of the Metasploitable Lab Series Lab 4 of 10 · 40% complete ⚠️ Authorised Lab Only. This lab exploits a real vulnerability against an intentionally vulnerable target. Run only on your isolated Metasploitable VM on a host-only network. Never run Metasploit modules against any system without explicit written authorisation. Five commands. That's all it takes. From a blank msfconsole to a root shell on Metasploitable in under 60 seconds using the vsftpd 2.3.4 backdoor. I'm…
Shadow AI Security Risks 2026 — The Unsanctioned AI Epidemic in Enterprise
The legal team had been using ChatGPT for six months before the security team found out. They'd discovered it was dramatically faster for contract summarisation — what took a paralegal four hours took the AI four minutes. They'd been pasting contracts in: client names, deal terms, confidential provisions, everything. The personal free-tier accounts they were using had conversation history enabled, data had been submitted to OpenAI's servers, and they had no idea whether any of it had been used for…
Metasploitable Service Enumeration Lab 2026 — Full Attack Surface Mapping | Hacking Lab 33
🧪 METASPLOITABLE LAB SERIESFREE Part of the Metasploitable Lab Series Lab 3 of 10 · 30% complete ⚠️ Isolated Lab Environment Only. Metasploitable 2 is intentionally vulnerable. Run it only on a host-only network completely isolated from the internet. Every service on this machine is exploitable. Lab 2 gave me 23 open ports. That's a list, not an attack plan. Service enumeration turns the port list into an attack priority matrix — I know which services are running vulnerable versions,…
How to Reverse a Real Android APK in 15 Minutes — Complete Beginner Guide 2026
Every Android APK is a ZIP file containing Java bytecode, resources, and a manifest. Unzip it, decompile it, and you have the developer's source code in a readable form. The hardcoded API key, the debug endpoint, the credentials baked in for "development only" — they're all there. I've found production AWS credentials, Stripe secret keys, and internal admin panel URLs in publicly available apps this way. Here's the exact workflow that takes any APK from download to decompiled source in…
