Typosquatting - the good, bad, and ugly
Let me get this out of the way first, there isn't much good about typosquatting, it's predominantly bad, and sometimes really ugly. Typosquatting is the registration of Internet domain names that appear similar to popular and reputable domains (e.g., vacebook.com instead of facebook.com). It is a common trick used by hackers who slightly misspell the name of a valid domain to fool the users wishing to access that domain. A study  conducted in 2015 concluded that just for the top 500 most popular websites over 10,000 malicious typosquatting domain is produced daily.
