Summary 4 | Small utility to generate similar IDN domain names. 5 | 6 | The main purpose of this utility is to generate similar domain name for you organization and block those domain via Office365/Exchange/Google apps admin. 7 | 8 | This can help prevent recent phishing attacks utilizing IDN domain names. 9 | 10 | You can read more about IDN attacks here: https://www.phish.ai/2018/03/13/idn-homograph-attack-back-crypto/ 11 | 12 | ## Example Usage 13 | python is required 14 | 15 | ```bash 16 | # Show help 17 | python3 main.py --help 18 | # This will print all the permutation of phish.ai, you can redirect the output to a file as well. 19 | python3 main.py phish .ai 20 | # This will print all the permutation of phish.ai in punycode (some admin dashboard support only this format of domains). 21 | python3 main.py phish .ai --punycode 22 | ``` 23 | 24 | ## Contribution 25 | This is an open-source tool and any pull-requests are welcome adding features/bug-fixes and new dictionaries. 26 | -------------------------------------------------------------------------------- /dictionary.py: -------------------------------------------------------------------------------- 1 | 2 | latin_script = { 3 | 'a': ['á','à','â','ǎ','ă','ã','ả','ȧ','ạ','ä','å','ḁ','ā','ą','ᶏ','ⱥ','ȁ','ấ','ầ','ẫ','ẩ','ậ','ắ','ằ','ẵ','ẳ','ặ','ǻ','ǡ','ǟ','ȁ','ȃ','ɑ'], 4 | 'b': ['ḃ','ḅ','ḇ','ƀ','ɓ','ƃ','ᵬ','ᶀ','ʙ','Ｂ','ｂ'], 5 | 'c': ['Ć','ć','Ĉ','ĉ','Č','č','Ċ','ċ','̄c̄','Ç','ç','Ḉ','ḉ','Ȼ','ȼ','Ƈ','ƈ','ɕ','ᴄ','Ｃ','ｃ'], 6 | 'd': ['ď','ḋ','ḑ','ḍ','ḓ','ḏ','đ','Ð','ð','̦d̦','ɖ','ɗ','ᵭ','ᶁ','ᶑ','ȡ','ᴅ','ｄ'], 7 | 'e': ['é','è','ê','ḙ','ě','ĕ','ẽ','ḛ','ẻ','ė','ë','ē','ȩ','ę','ᶒ','ȅ','ế','ề','ễ','ể','ḝ','ḗ','ḕ','ȇ','ẹ','ệ','ⱸ','ᴇ','ｅ'], 8 | 'f': ['Ḟ','ḟ','Ƒ','ƒ','ᵮ','ᶂ','ꜰ','Ｆ','ｆ'], 9 | 'g': ['ǵ','ğ','ĝ','ǧ','ġ','ģ','ḡ','ǥ','ᶃ','ｇ'], 10 | 'h': ['ĥ','ȟ','ḧ','ḣ','ḩ','ḥ','ḫ','̱ẖ','ħ','ⱨ','ɦ','ｈ'], 11 | 'i': ['Í','í','Ì','ì','Ĭ','ĭ','Î','î','Ǐ','ǐ','Ï','ï','Ḯ','ḯ','Ĩ','ĩ','Į','į','Ī','ī','Ỉ','ỉ','Ȉ','ȉ','Ȋ','ȋ','Ị','ị','Ḭ','ḭ','Ɨ','ɨ','ᵻ','ᶖ','İ','ı','ɪ','Ｉ','ｉ'], 12 | 'j': ['Ĵ','ĵ','ɉ','̌ǰ','ȷ','ʝ','ɟ','ʄ','ᴊ','Ｊ','ｊ','I'], 13 | 'k': ['Ḱ','ḱ','Ǩ','ǩ','Ķ','ķ','Ḳ','ḳ','Ḵ','ḵ','Ƙ','ƙ','Ⱪ','ⱪ','ᶄ','ᶄ','Ꝁ','ꝁ','ᴋ','Ｋ','ｋ'], 14 | 'l': ['Ĺ','ĺ','Ľ','ľ','Ļ','ļ','Ḷ','ḷ','Ḹ','ḹ','Ḽ','ḽ','Ḻ','ḻ','Ł','ł','Ŀ','ŀ','Ƚ','ƚ','Ⱡ','ⱡ','Ɫ','ɫ','ɬ','ᶅ','ɭ','ȴ','ʟ','Ｌ','ｌ'], 15 | 'm': ['Ḿ','ḿ','ṁ','Ṃ','ṃ','ᵯ','ᶆ','Ɱ','ɱ','ᴍ','Ｍ','ｍ'], 16 | 'n': ['Ń','ń','Ǹ','ǹ','Ň','ň','Ñ','ñ','Ṅ','ṅ','Ņ','ņ','Ṇ','ṇ','Ṋ','ṋ','Ṉ','ṉ','̈n̈','Ɲ','ɲ','Ƞ','ƞ','ᵰ','ᶇ','ɳ','ȵ','ɴ','Ｎ','ｎ','Ŋ','ŋ'], 17 | 'o': ['Ó','ó','Ò','ò','Ŏ','ŏ','Ô','ô','Ố','ố','Ồ','ồ','Ỗ','ỗ','Ổ','ổ','Ǒ','ǒ','Ö','ö','Ȫ','ȫ','Ő','ő','Õ','õ','Ṍ','ṍ','Ṏ','ṏ','Ȭ','ȭ','Ȯ','ȯ','Ȱ','ȱ','Ø','ø','Ǿ','ǿ','Ǫ','ǫ','Ǭ','ǭ','Ō','ō','Ṓ','ṓ','Ṑ','ṑ','Ỏ','ỏ','Ȍ','ȍ','Ȏ','ȏ','Ơ','ơ','Ớ','ớ','Ờ','ờ','Ỡ','ỡ','Ở','ở','Ợ','ợ','Ọ','ọ','Ộ','ộ','Ɵ','ɵ','ⱺ','ᴏ','Ｏ','ｏ'], 18 | 'p': ['Ṕ','ṕ','Ṗ','ṗ','Ᵽ','ᵽ','Ƥ','ƥ','̃p','̃ᵱ','ᶈ','ᴘ','Ｐ','ｐ','ȹ'], 19 | 'q': ['Ɋ','ɋ','ʠ','Ｑ','ｑ','ȹ'], 20 | 'r': ['Ŕ','ŕ','Ř','ř','Ṙ','ṙ','Ŗ','ŗ','Ȑ','ȑ','Ȓ','ȓ','Ṛ','ṛ','Ṝ','ṝ','Ṟ','ṟ','Ɍ','ɍ','Ɽ','ɽ','ᵲ','ᶉ','ɼ','ɾ','ᵳ','ʀ','Ｒ','ｒ'], 21 | 's': ['ẞ','ß','Ś','ś','Ṥ','ṥ','Ŝ','ŝ','Š','š','Ṧ','ṧ','Ṡ','ṡ','ẛ','Ş','ş','Ṣ','ṣ','Ṩ','ṩ','Ș','ș','̩s̩','ᵴ','ᶊ','ʂ','ȿ','ꜱ','Ｓ','ｓ'], 22 | 't': ['Ť','ť','Ṫ','ṫ','Ţ','ţ','Ṭ','ṭ','Ț','ț','Ṱ','ṱ','Ṯ','ṯ','Ŧ','ŧ','Ⱦ','ⱦ','Ƭ','ƭ','Ʈ','ʈ','̈ẗ','ᵵ','ƫ','ȶ','ｔ'], 23 | 'u': ['Ú','ú','Ù','ù','Ŭ','ŭ','Û','û','Ǔ','ǔ','Ů','ů','Ü','ü','Ǘ','ǘ','Ǜ','ǜ','Ǚ','ǚ','Ǖ','ǖ','Ű','ű','Ũ','ũ','Ṹ','ṹ','Ų','ų','Ū','ū','Ṻ','ṻ','Ủ','ủ','Ȕ','ȕ','Ȗ','ȗ','Ư','ư','Ứ','ứ','Ừ','ừ','Ữ','ữ','Ử','ử','Ự','ự','Ụ','ụ','Ṳ','ṳ','Ṷ','ṷ','Ṵ','ṵ','Ʉ','ʉ','ᵾ','ᶙ','ᴜ','Ｕ','ｕ','ᵫ'], 24 | 'v': ['Ṽ','ṽ','Ṿ','ṿ','Ʋ','ʋ','ᶌ','ᶌ','ⱱ','ⱴ','ᴠ','Ｖ','ｖ'], 25 | 'w': ['Ẃ','ẃ','Ẁ','ẁ','Ŵ','ŵ','Ẅ','ẅ','Ẇ','ẇ','Ẉ','ẉ','ẘ','ẘ','Ⱳ','ⱳ','ᴡ','Ｗ','ｗ'], 26 | 'x': ['Ẍ','ẍ','Ẋ','ẋ','ᶍ','Ｘ','ｘ'], 27 | 'y': ['Ý','ý','Ỳ','ỳ','Ŷ','ŷ','ẙ','Ÿ','ÿ','Ỹ','ỹ','Ẏ','ẏ','Ȳ','ȳ','Ỷ','ỷ','Ỵ','ỵ','Ɏ','ɏ','Ƴ','ƴ','ʏ','Ｙ','ｙ'], 28 | 'z': ['Ź','ź','Ẑ','ẑ','Ž','ž','Ż','ż','Ẓ','ẓ','Ẕ','ẕ','Ƶ','ƶ','Ȥ','ȥ','Ⱬ','ⱬ','ᵶ','ᶎ','ʐ','ʑ','ɀ','ᴢ','Ｚ','ｚ'] 29 | } -------------------------------------------------------------------------------- /main.py: -------------------------------------------------------------------------------- 1 | import argparse 2 | from dictionary import latin_script 3 | 4 | 5 | def permutate(domain, tld, punycode=False): 6 | res = [] 7 | for i,char in enumerate(domain): 8 | prefix = domain[:i] 9 | suffix = domain[i+1:] 10 | if char in latin_script: 11 | for perchar in latin_script[char]: 12 | new_domain_name = prefix + perchar + suffix + tld 13 | if punycode: 14 | new_domain_name = str(new_domain_name.encode('idna'), 'utf-8') 15 | res.append(new_domain_name) 16 | 17 | return ','.join(res) 18 | 19 | 20 | def main(): 21 | parser = argparse.ArgumentParser() 22 | parser.add_argument('domain') 23 | parser.add_argument('tld') 24 | parser.add_argument('--punycode', default=False, action='store_true') 25 | args = parser.parse_args() 26 | print(permutate(args.domain, args.tld, punycode=args.punycode)) 27 | 28 | 29 | if __name__ == '__main__': 30 | main() 31 | --------------------------------------------------------------------------------
