#COOL READER ANDROID PDF INSTALL#
Unlike few years earlier, when for reading PDF files on Android, there was only option to install Adobe’s official PDF Reader app – now PDF reading and editing on Android has changed. There are many PDF reader for Android that help you read/edit PDF files on Android. Since more and more publishers are preferring PDF as most effective format to publish eBooks, it becomes very important to access and read PDF files on Android phones/tablets especially when we are quickly heading towards an era where smartphones are making our lives increasingly more convenient. Please have a look at my monthly magazine.PDF is one of the most popular light weight file format of digital documents. On observation we can see a stream that looks like shellcode present in object 8. Using pdf-parser with the ‘c’ option will display the content for objects without streams or with streams without filters.
Similarly in object 9 we can see a JavaScript action. We can see it has a launch action which launches the cmd.exe. Let us parse the object 10 as shown below. We can also parse each object of the pdf file. On observation, objects 10 and 9 evoke some interest. That will parse the entire PDF and its objects (We saw earlier that our malicious pdf contains 12 objects). Type command “ pdf-parser /root/Desktop/evil.pdf” without quotes. It will parse a PDF document to identify the fundamental elements used in the analyzed file. Now if we want to do further analysis on the malicious PDF, we can use another tool called pdf-parser. Now coming to the malicious PDF, we can disable the malicious elements of the file using pdfid as shown below. Now let us analyze my monthly magazine as shown below.Īs you have seen above, it’s totally clean. As we can see below, the evil.pdf has JavaScript, Open action and launch objects which are indeed malicious. Let us first analyze the pdf we created with Metasploit as shown below. Pdfid will scan a file to look for certain PDF keywords, allowing you to identify PDF documents that contain (for example) JavaScript or execute an action when opened. It will also handle name obfuscation. Another file we will be analyzing is the PDF copy of my Hackercool monthly magazine. When the target user clicks on it, we will get reverse_tcp connection. This PDF file can be sent to our target using any social engineering technique. By the end of this article, you will be able to tell whether the pdf you received is genuine or malicious.įor this howto, I will create a malicious PDF with Metasploit using the following exploit.Īs is well known, this exploit hides an exe within a PDF file. So I thought it would be good to make a howto on pdf forensics. But some of the security conscious readers have raised concerns whether this pdf magazine may be booby trapped to hack my readers.
The test edition was received positively. I am very happy and the cause for my happiness is the Hackercool pdf monthly magazine I recently started.
