This is a simple single-file python program that can find basic XSS (cross-site scripting) vulnerabilities in a target url. Most XSS discovery tools use a payload refelection strategy in which payloads are injected in url parameters and the GET response is inspected for places where the payload content is reflected. This is a very low precision XSS detection strategy because most reflection does not support execution. This program uses a different approach, and instead opens the target url in a browser, tests alert(...) payloads directly in the browser context, and listens for an alert being…

Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

I built Site Spy after missing a visa appointment slot because a government page changed and I didn’t notice for two weeks. It watches webpages for changes and shows the result like a diff. The part I think HN might find interesting is that it can monitor a specific element on a page, not just the whole page, and it can expose changes as RSS feeds. So instead of tracking an entire noisy page, you can watch just a price, a stock status, a headline, or a specific content block. When it changes, you can inspect the diff, browse the snapshot history, or follow the updates in an RSS reader. It’s…

I noticed the growing security concerns around MCP (https://news.ycombinator.com/item?id=43600192) and built an open source tool that can detect several patterns of tool poisoning attacks, exfiltration channels and cross-origin manipulations. MCP-Shield scans your installed servers (Cursor, Claude Desktop, etc.) and shows what each tool is trying to do at the instruction level, beyond just the API surface. It catches hidden instructions that try to read sensitive files, shadow other tools' behavior, or exfiltrate data. Example of what it detects: - Hidden instructions…

http://webscanner.tk/quickscan/ Hi! I made this project over the couse of a week to help teach myself more about Django and web app development. I am studying computer security in school and web security is one of my passions. It is a tool that helps web developers ensure that they have implemented helpful security mechanisms like HTTPOnly flags, X-Frame-Options, etc. There are hundreds of tools that offer to scan websites for things like cross-site scripting, mySQL injection, etc. This tool simply looks for information that is available via one or two GET requests (the headers, protocols,…

I built this after seeing multiple teams accidentally ship API keys in their frontend code. The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a tag visible to anyone who opens DevTools. I've personally witnessed this happen to at least 3-4 production apps in the past year alone. KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS/Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT…

Live extension analysis: Point us at a Chrome/Edge/Firefox extension (store URL or CRX). We spin up a safe sandbox and observe it in real time—permissions use, message passing, storage writes, network calls, remote code loading, and UI injections. Package scanning: Paste an npm/package URL or code. We do quick static + dynamic checks: install/postinstall scripts, obfuscation/eval, exfil endpoints, suspicious APIs, and typosquat/reputation signals. AI explainer: An LLM summarizes the behaviors and risk patterns in plain English (why it’s risky, what to verify,…

hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…
