Hi This paper sheds light on the modified approach to trigger web attacks through JavaScript protocol handler in the context of browser when a PDF is opened in it.

The attack is targeted on the web applications that allow PDF documents to be uploaded on the web server. http://secniche.org/papers/SNS_09_03_PDF_Silent_Form_Re_Purp_Attack.pdf Regards Aditya KS http://www.secniche.org
