4NTL – Threat Intel Lookup

Select an IP, hash, domain or URL, right-click, and see VirusTotal and AbuseIPDB verdicts right where you are.

Stop copy-pasting indicators into threat-intel sites. ★ Install now and 4NTL stays free for you, for life. Select an IP address, domain, URL or file hash on any page, right-click, and 4NTL shows the VirusTotal and AbuseIPDB verdicts in a small card right next to your cursor. No new tabs, no copy-paste, no losing your place. BUILT FOR ANALYSTS • One click from the right-click menu, or select and press Alt+Shift+L. • Understands analyst text: defanged indicators such as 1.2.3[.]4 or hxxps://evil[.]com, addresses with ports, and log fields. Select a whole log line and pick the indicator you want. • Checks where links and buttons really go, even when a site hides the address in JavaScript. For buttons that only get an address when clicked, click once: 4NTL catches the destination and stops the page from going there. • Sees through the protected and redirect links that email security tools and social sites add, and checks the real destination. • Check the page you're on from the toolbar icon, or type "4ntl" and a space in the address bar and paste anything. • Copy just the indicator, or the whole report as text for a ticket. • Saved list: keep the indicators you find during an investigation, then copy them all at once or download a CSV. • Country flags at a glance. PRIVATE AND LIGHT • Uses your own free API keys, stored only in your browser. • Private and internal addresses are never sent anywhere. • Only reads existing reports; never submits anything for analysis. • Repeat lookups come from a short in-memory cache and don't use your quota. • Nothing runs on a page until you use 4NTL there. No analytics or tracking. MAKE IT YOURS Light, dark and Sharingan themes, your own colors, and a card you can drag anywhere.
