PDFs, while a convenient format for document sharing, can also come with severalf vulnerabilities that can put users at risk. In this blog post, we'll explore the various ways that PDFs can be vulnerable and how to protect yourself and your files. In addition, a PDF editor can assist you in making your PDFs more secure.

JavaScript

PDFs may contain embedded JavaScript code, which can be utilized to run malicious scripts on your computer. This can be used to steal personal information, install malware, or perform harmful actions. Disable JavaScript in your PDF viewer or viewer with built-in security features.

To protect yourself, be cautious when clicking on links in PDFs, and don't open PDFs from unknown sources. A PDF file editor can help you verify the credibility of the source before opening a PDF.

PDF Ubiquity

PDFs are often overlooked as a security risk. Many users don't realize that they can be used to distribute malware or steal personal information. To protect yourself, be sure that PDFs cannot be used to attack you, and take the same precautions you would with any other file type.  PDF security software will help you identify any potential threats.

PDF Hyperlinks

PDFs can contain hyperlinks that can take you to malicious websites or download malware to your computer. To protect yourself, hover over links in PDFs before clicking on them to see where they lead and don't click on links from unknown sources. An online PDF editor can help you verify the credibility of the link before clicking on it.
