If no files are visible, press CTRL and H together to find hidden files and folders.īefore we send the malicious file to our victim, we need to set up a listener to capture this reverse connection.Īs the victim opens the malicious file, the session with the victim has been established and we can access the victim’s system by using meterpreter.

Once we have all the options set the way we want, we run “exploit” to create our malicious file. Open msfconsole and execute the following command. The steps for creating our malicious PDF file are as follows: Adobe Reader is prone to a stack-based buffer-overflow vulnerability. We are going to be using the Adobe Reader “util.printf()” JavaScript function stack buffer overflow vulnerability to create a malicious PDF file. When we open any malicious PDF file, it will execute the JavaScript and it exploits the JavaScript after that, the shell code is processed and a Trojan will be executed from the Internet.Ĭreate a malicious PDF file with Metasploit We can embed the malware in our PDF by using JavaScript because JavaScript commonly uses heap spray to exploit. We can use one of the many Adobe Acrobat exploits in the Metasploit framework to embed an exe with PDF.Ĭmd will be opened by using the above launch action. PDF Document Structure Execute malware with PDFĪ launch action launches an application or opens or prints a document. Streams, usually containing large amounts of data.Dictionaries, collections of objects indexed by names.Boolean values, representing true or false.The general structure of a PDF file is composed of the following code components:

In most cases, the embedded scripts are responsible for dropper functionality, or else there is a need to install an OS-based malware on the victim’s system. JavaScript is the most popular for this purpose. The scripts that are responsible for malicious behavior can be written in a scripting language that PDF supports. Normally, the PDF malware’s malicious behavior is in a script that is embedded In PDF files.

In previous years, cybercriminals embedded malicious script to install malware and steal user credentials. The dynamic PDF capabilities mentioned above can and have been used to house malicious content. While we have all benefited from this feature-rich information-sharing venue, there exists a darker side.

Combined, these elements can deliver a visually appealing, interactive, and portable document. The PDF has ability to deliver rich contents (static and dynamic). Here is the information you’ll need to know.

It’s good to know how to analyze PDF files, but analysts first need a basic understanding of a PDF before they deem it malicious. Malicious PDF files are frequently used as part of targeted and mass-scale computer attacks for these reasons. 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. 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. Previous years were not good for PDF users, as several vulnerabilities were published, such as buffer overflow vulnerability in versions prior to version 9. The PDF format is used in almost all companies to share business deals, company brochures, and even invitations. It’s hard to imagine business proposals without PDFs. PDF files have become very common in everyday work.
