IP Info - Chrome Extension

IP Info is a Chrome extension that lets you analyze websites by fetching their IP address, location, open ports, and security-related tags using Shodan InternetDB and GeoNet (ipinfo.io) APIs. It helps assess the risk level of a website based on known vulnerable ports and tags associated with malware, botnets, and more.

Features

• Extracts IP address from the current tab’s domain
• Displays geographic data of the server the website is running on (country, city, region, coordinates).
• Shows open ports and highlights risky ones, provides information for flagged open ports.
• Lists Shodan tags indicating potential threats
• Computes a risk score and labels the site as Safe, Low, Medium, High, or Critical
• Includes a direct link to view the server’s location on Google Maps
• Shows if a website is running on HTTP (insecure) or HTTPS (secure)

APIs Used

• Shodan InternetDB – Retrieves open ports and tags
• ipinfo.io – Fetches geographic data (via GeoNet API)
• Google DNS over HTTPS – Resolves domain to IP

Risk Assessment Logic

The extension uses custom scoring tables to assess risk

Risky Ports (examples)

• 23 (Telnet) - Insecure and deprecated - 10 pts
• 445 (SMB) - Exploitable by ransomware - 10 pts
• 3389 (RDP) - Common target for attacks - 15 pts

Dangerous Tags

Tags like malware, botnet, tor, and blacklist increase the site's risk score.

Risk Levels

• Safe (0)
• Low (1–10)
• Medium (11–25)
• High (26–50)
• Critical (51+)

How It Works

• Popup Opens → Automatically grabs the active tab's URL
• Domain to IP → Uses Google DNS API to resolve domain
• Geolocation → Fetches IP location from ipinfo.io
• Shodan Scan → Gets open ports + tags from InternetDB
• Risk Score → Evaluated using weighted scores
• Display Info → Results rendered with severity colors
