Description
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, integration into security tools, or whatever you need.Happy to answer questions about the scraping approach or data collection methods.

Same idea, different domain
Nobody's really built a analytics & bi tool for Legal yet.
