Homoglyph Attack Generator and Punycode Converter

Homoglyph Attack Generator

     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.

For more information see my Paper Proposal for "Out of Character: Use of Punycode and Homoglyph Attacks to Obfuscate URLs for Phishing".

1st, type in a name to look like:
2nd, choose homoglyphs to use:

3rd, Output will be something like this:

Output appears here.

4th submit so PHP can generate the IDNA/Punycode:

Unicode URL to give out:
Encoded label to set up in DNS:

Below is phlyLabs original converter if you want to try taking the Homograph back and forth:

Original (Unicode) Punycode (ACE)



PHP code based on examples and libraries from phlyLabs Berlin; part of phlyMail
Also thanks to http://homoglyphs.net for helping me find more glyphs.

Changes:
11/28/2017: Added ḍ as sugested by rockethamster. 3/11/2012: Added option to use 'Right-To-Left Override' (U+202E) so you can do some stupied EXE tricks, and added a linkless output so you can copy & paste your homography without formatting. 3/11/2012: Added ノ for /. 4/3/2012: I found a list of IDN blacklisted characters on Mozilla's site and added them. I also added a table of the homoglyphs I'm using.
3/6/2012: ٠ was also suggested by @Voulnet.
3/5/2012: @Voulnet suggested I add Arabic letter ا. I put it in for l, i, | and 1.
