README

This app is meant to make it easier to generate homographs based on Homoglyphs than having to search for look-a-like character in Unicode, then coping and pasting. Please use only for legitimate pen-test purposes and user awareness training. I also recommend webapp developers use it to test out possible user impersonation attacks in their code. This is still a work in progress, so please send me suggestions (especially for new Homoglyphs to add). While this tool was designed with making IDNA/Punycode names for putting into DNS to display foreign characters in a browsers URL bar, it can be used for other things. Try ignoring the IDNA/Punycode stuff and just making look alike user names for systems that accept Unicode. I made this tool to easily generate homographs based on homoglyphs in Unicode and to test out how different apps display them. It seems like a lot of modern browsers have gotten better at warning the users of attack, but I'd love to hear experiences about other apps that accept Unicode/Punycode/Internationalized Domain Names, especially webapps.

Requirements

PHP 7.4 and leter

Modules: mbstring, iconv, intl

Composer

You can install the bindings via Composer. Run the following command:

composer require pavlo-dot-dev/homoglyph-attack-generator

Dependencies

The bindings require the following extensions in order to work properly:

• mbstring (Multibyte String)
• iconv
• intl (Internationalization extension)

If you use Composer, these dependencies should be handled automatically. If you install manually, you'll want to make sure that these extensions are available.

Getting Started

Simple usage looks like:

$generator = new \PavloDotDev\HomoglyphAttackGenerator\Generator();
$results = $generator->generate('cocacola', true);
print_r($results);

$generator = new \PavloDotDev\HomoglyphAttackGenerator\Generator();
$results = $generator->generate('cocacola', false);
print_r($results);
