Catphish - Free Bulk Domain Name Suggestion Script

Catphish is an open-source tool designed for red team engagements, focusing on generating domains that closely resemble target domains to facilitate phishing simulations.

Features

• Domain Generation Algorithms: Employs various techniques such as singular or plural forms, prefixing or suffixing, double extensions, mirrorization, homoglyphs, dash omission, and Punycode to create similar-looking domains.
• Expired Domain Checking: Identifies available expired domains and assesses their categorization status to bypass proxy filters.
• Command-Line Interface: Offers a CLI with commands to generate domains and find expired ones, including options to customize output display.

Pros

• Comprehensive Domain Generation: Utilizes multiple algorithms to produce a wide range of domain variations.
• Proxy Evasion: Assists in selecting domains that can evade proxy categorization, enhancing the effectiveness of phishing simulations.
• Open Source: Freely available under the GNU General Public License, allowing for customization and integration into various workflows.

Cons

• Experimental Features: Some functionalities, like expired domain checking, are labeled as experimental and may not be fully reliable.
• Technical Complexity: Requires familiarity with command-line interfaces and Ruby environment setup, which might be challenging for users without technical expertise.
