I kept seeing the same advice in prompt injection threads. Wrap untrusted content in random delimiters, tell the model "everything inside these markers is data, not instructions," and hope it respects the boundary. Sounds reasonable. I couldn't find anyone who actually measured whether it works. So I did. I'm building a system where LLM-generated output feeds into downstream decisions. The inputs
Hello everyone, I'm @xiaoqiangapi, the Chinese teacher who gives apis a "check-up". An article on , my SQL injection, XSS and prompt hijacked, API are blocked off. Let's take a different approach today - ** not attack, test 'resilience' **. Would the API crash if a sudden wave of requests came in, or if someone typed several thousand characters? I'm curious about it. The tools are still the same o
I finished an English series on the way I think ordinary people can start using AI for real work. The point is not to become an AI expert first. The point is to have one place where you can say what you want, give the tool access to the right folder, and check the result. Anything important still needs a human pause: publishing, deleting, paying, or authorizing. My preferred starting point is simp
This presentation is an adaptation of a keynote address delivered by Sasha Le, Senior Engineer, Tide Foundation at the launch event of the RMIT AWS Innovation Lab (RAIL) on 21st of April, 2026 In 2022, a ransomware group named Lapsus$ breached some of the most sophisticated tech companies on the planet. The list included Microsoft, Nvidia, Okta, Uber, and Samsung. The ringleader wasn't a state-spo

This is Indirect Prompt Injection, and if you are piping raw email bodies into an LLM, you are currently hosting an open-invitation party for every spammer in your inbox. Phase 1: The Architectural Bet The Vendor Trap tells you that a "sufficiently smart"
Imagine you have a Nodejs server with endpoint that performs heavy CPU operations. By default your server runs on a single thread. This means it will freeze depending on the CPU load. If your server has other asynchronous endpoints, for example, to execute database operations, those endpoints would become unresponsive while the heavy load endpoint is processing. Our first idea is to create more th
📂 Series: SIEM Deployment Alright, let's talk shop. After over a decade in the trenches – from building out SOCs from scratch to wrangling SIEMs like Splunk, QRadar, and Microsoft Sentinel in some seriously high-stakes environments – I've seen a lot of tools come and go. Some are brilliant, some are overhyped, and some just… work. Wazuh falls firmly into that last category, with a generous helpin
