Cyber Rebels — the free cybersecurity toolkit

Cyber Rebels is a free, browser-based cybersecurity toolkit for analysts and curious defenders. It brings threat intelligence, phishing analysis, OSINT, and personal privacy tools together in one place — no sign-up, and nothing leaves your browser unless a lookup requires it.

Threat Center

The Investigate Console correlates VirusTotal, AbuseIPDB and Shodan on any IP, domain, URL or file hash, with live geolocation. Round it out with the Email & Phishing checker, Domain Intel (registration age, DNS and a risk score), a URL redirect analyzer, an SSL certificate inspector, a QR code safety scanner, the Intel Radar of actively-exploited vulnerabilities, and a decoder bench.

OSINT & privacy

Search a handle across platforms with Username Search, map your public footprint, and check exactly what the web knows about you with Am I Being Tracked? and the browser fingerprint test. Then lock it down with honest VPN recommendations and de-Google guidance.

Learn & defend

Hands-on interactive labs teach password hashing, password cracking, IP addressing and how network traffic flows, and the guides and blog explain privacy and security in plain English. Enable JavaScript for the full interactive toolkit.
