Parse URLs for internationalized domain names.
Parse URLs for internationalized domain names. This may be a sign that the URL is an internationalized domain name (IDN) homograph attack*, otherwise known as a URL phishing attack.
For example, you may find a URL that looks like "https://www.еріс.com", but it's actually the unicode domain: https://www.xn--e1awd7f.com/ (in Punycode). By using similar looking Cyrillic letters, "www.еріс.com" looks like the actual URL "www.epic.com" written in ASCII characters.
