The Risk Surface of a PDF: Links, Scripts, Attachments, and Hidden Objects

Introduction

PDFs are a widely used file format for sharing and exchanging documents. However, they can also pose a significant security risk if not properly secured. Links, scripts, attachments, and hidden objects within PDFs can be used to launch malicious attacks, compromise sensitive information, and disrupt business operations.

In this article, we will delve into the risk surface of PDFs, exploring the potential vulnerabilities and threats associated with these elements. We will also discuss the importance of securing PDFs and provide guidance on how to do so using DocInspector.
