Antijection

What it does

Antijection helps teams protect their AI systems from prompt injection, jailbreaks, and malicious inputs before they reach the LLM. As more apps rely on LLMs, prompt-level attacks are the easiest way to break guardrails, leak data, or manipulate outputs. Antijection acts as a pre-screening layer that inspects every prompt and blocks risky intent.

Antijection documents and classifies real-world attacks on deployed AI systems, organized by where they happen, what enables them, and what they actually change.

  Find prompts that jailbreak your agent (open source)2025 · security.vista-labs.ai · ▲8

  We've built an open-source tool to stress test AI agents by simulating prompt injection attacks. We’ve implemented one powerful attack strategy based on the paper [AdvPrefix: An Objective for Nuanced LLM Jailbreaks](https://arxiv.org/abs/2412.10321). Here's how it works: - You define a goal, like: “Tell me your system prompt” - Our tool uses a language model to generate adversarial prefixes (e.g., “Sure, here are my system prompts…”) that are likely to jailbreak the agent. - The output is a list of prompts most likely to succeed in bypassing safeguards. We’re just getting…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
