20 Years ago Adobe created Portable Document Format that we called as PDF to be common format for any of the device it uses to view or print. But unfortunately so many exploits uses PDF files to attack computers.
Mikko Hypponen, Chief Research Officer at F-Secure Corporation, has been tracking the use of PDF files by malware coders, both as widespread threats and threats targeted for specific purposes. Now it’s revealed PDFs can contain embedded videos, music, and 3D objects with JavaScript for rendering. Not only even these it can launch executable files and can send data to the remote server. So it’s no wonder there are regular security problems with PDF readers in general.
But everywhere have to use PDF then how we can be secure completely avoid opening PDF documents on local machines instead of the use services such as Google Docs. If you're using Chrome, Firefox, or Opera, you can install the gPDF plug-in to automate the process for web-based PDFs. For your local files use a PDF reader that's as unpopular as possible fewer users a product has, the less attacks it will attract.
