The Social Aspect Dns And Phishing

Unlike the exact processing of an IP address for some computer code, the use of a domain name is a much less rigorous process for people. The address can easily be mistyped as, and an email containing an address like http://www. can effectively be used in phishing attacks for luring users to malicious websites.

Education is always the primary method for preventing these kinds of attacks.
