Analyzing Malicious PDFs
Analyzing Malicious PDFs: PDF files have become very common in everyday work. It’s hard to imagine business proposals without PDFs. The PDF format is used in almost all companies to share business deals, company brochures, and even invitations.
Previous years were not good for PDF users, as several vulnerabilities were published, such as buffer overflow vulnerability in versions prior to version 9. A lot of the attacks were observed trying to abuse the bug by using social engineering or by hosting malicious PDF files on the Internet. Just the simple act of opening the PDF file could exploit a vulnerability to automatically download malicious code from the internet, and display a decoy PDF file to trick you into believing that nothing wrong has happened.
