Facebook is a popular social networking site started in 2004 by Mark Zuckerberg. It began as a social network of Harvard students to get to know each other but within months other colleges became part of it to. By the end of the following year Facebook was opened to the public and has been growing ever since and on the 21 July 2010 hit half a billion users.
There are many security issues surrounding Facebook including identity theft, malware, social engineering, phishing and privacy.
Social engineering - also called no-tech hacking - is when the identity thief surfs through profiles that have relaxed security settings or gain access by friending people. They gather the personal details that the user has freely published about themselves. These details may be adequate enough for the thief to assume the users identity. However, there is another use for these details; no-tech hacking into other accounts the user might have. This was the case 2009 when a hacker called Croll managed to gain access to some of Twitter's employee accounts just by using information that was available to the public.
On Facebook third party applications can access user information. Accepting an application will grant it these rights. It is important to be careful about accepting applications because they could contain malware or phishing software. The programmers of the fake Facebook dislike button took advantage of people wanting to be able to 'dislike' rather than 'like' something and put their malicious program in that. The application granted the programmer access to the user's personal profile and details.
