Understanding Domain Permutation and Protecting Your Brand with Dnstwist
In the digital age, the security of a brand's domain name is paramount. Cybercriminals often exploit similar-looking domain names to create fraudulent websites, a practice known as 'domain permutation'. This can lead to 'typosquatting', where users inadvertently visit a malicious site due to a typographical error, or 'phishing', where fake sites mimic legitimate ones to steal user information.
What is Domain Permutation?
Domain permutation involves creating variations of a domain name by altering its characters, adding or subtracting elements, or using different top-level domains (TLDs). This can result in numerous similar-looking domain names that can be used for nefarious purposes.
