GasMasK is an open source OSINT (Open Source Intelligence) tool designed to perform reconnaissance and information gathering on domains and online targets. It is implemented as a Python-based command-line utility that collects data from numerous publicly available sources across the internet. It aggregates intelligence such as domain details, email addresses, hostnames, and subdomains by querying search engines, DNS records, certificate transparency logs, and security databases. GasMasK integrates with a wide range of platforms and services including search engines, social media platforms, and security APIs to retrieve relevant information about a target. These sources include services like Shodan, Censys, Netcraft, VirusTotal, GitHub, and various DNS-related services, allowing investigators to build a comprehensive profile of a domain or organization. GasMasK is commonly used by penetration testers, red teams, and security researchers who need to collect reconnaissance data.
