Think of Local sheriff as a recon tool in your browser (WebExtension). While you normally browse the internet, Local Sheriff works in the background to empower you in identifying what data points (PII) are being shared / leaked to which all third-parties. - ghostery/local-sheriff

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…

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,…

localscope is a small Python package that disassembles functions to check if they access global variables they shouldn't. I wrote this a few years ago to detect scope bugs which are common in Jupyter notebooks. It's recently come in handy writing jax code (https://github.com/jax-ml/jax) because it requires pure functions. Thought I'd share.

Hi HN, I’m one of the maintainers of Bridge Anonymization. We built this because the existing solutions for translating sensitive user content are insufficient for many of our privacy-concious clients (Governments, Banks, Healthcare, etc.). We couldn't send PII to third-party APIs, but standard redaction destroyed the translation quality. If you scrub "John" to "[PERSON]", the translation engine loses gender context (often defaulting to masculine), which breaks grammatical agreement in languages like French or German. So we built a reversible, local-first pipeline for Node.js/Bun. Here…

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,…
