Today’s hackers are becoming increasingly sophisticated in planning and executing well designed multi-vector attacks. It used to be that attackers only employed a singular strategy to attack end users or computer systems. For example, virus attacks used to be spread by an email attachment. However with the mass adoption of email security products such as the Barracuda Spam & Virus Firewall and increased public awareness, these attacks are no longer effective since most attacks are quickly contained or blocked once detected.
A hacker is at once a rogue computer expert and a social psychologist who understands how people react. In order to have any efficacy, today’s hacker must now use a number of mechanisms in tandem in order to trick users into sending personal data or downloading malicious software. A well disguised spam email that takes a user to a legitimate Web site that has been compromised in advance with a Cross-Site Scripting (XSS) attack to use social engineering techniques to steal personal or financial information is a typical example of the elaborate web a hacker weaves.
