Malicious chromium extensions

  1. 1DU

    Hey HN, I built an automated system that tracks malicious Chrome/Edge extensions daily. The database updates automatically by monitoring chrome-stats for removed extensions and scanning security blogs. Currently tracking 1000+ known malicious extensions with extension IDs, names, and dates. I'm working on detection tools (GUI + CLI) to scan locally installed extensions against this database, but wanted to share the raw data first since maintained threat intelligence lists like this are hard to find. The automation runs 24/7 and pushes updates to GitHub. Free to use for research,…

    OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…

    Hi everyone, My motivation for building this was to address the trouble of mass unsubscribing from unwanted emails and deleting bulk emails while ensuring privacy and control over the process. With this Chrome extension, emails are not sent to any external servers. All calls to the Gmail API happen locally on your device. Feedback and suggestions are welcome!

    Hey HN, I'm Arjun, an 18-year-old intern at Socket. I've been working on a project that I'm really excited to share with you all - a browser extension that makes it easier to check the security of NPM packages before you use them. You can try the extension on any Chromium-based browser or on Firefox. Chrome extension: https://chrome.google.com/webstore/detail/socket-security/jb... Firefox add-on: https://addons.mozilla.org/en-US/firefox/addon/socket-securi... Socket scans NPM packages for malware, vulnerabilities, code smell, and…
