User-generated content is Achilles’ heel of social media sites

User-generated content is the “Achilles’ heel” of social media sites, warns a new report by data security firm Imperva that examines the recent hack of the MilitarySingles.com site by LulzSec. 

In its report ‘Dissecting a Hacktivist Attack’, Imperva explained LulzSec was able to gain access to personal information of users on the MilitarySingles.com by using a remote file inclusion (RFI) attack against PHP-based applications, which compromise 77% of web applications.
