** Home page **

** Dependencies **
- In order to analyse Javascript code "PyV8" is needed:
https://github.com/buffer/pyv8
git clone https://github.com/buffer/pyv8.git
cd pyv8
python setup.py build
sudo python setup.py install
cd ..
rm -rf pyv8
- The "sctest" command is a wrapper of "sctest" (libemu). Besides libemu pylibemu is used and must be installed:
https://github.com/buffer/libemu
https://github.com/buffer/pylibemu
git clone https://github.com/buffer/libemu.git
autoreconf -v -i
./configure --prefix=/opt/libemu
sudo make install
sudo pip install pylibemu
- To support XML output "lxml" is needed:
http://lxml.de/installation.html
- Included modules: lzw, colorama, jsbeautifier, ccitt, pythonaes (Thanks to all the developers!!)
** Installation **
No installation is needed apart of the commented dependencies, just execute it!
** Execution **
There are two important options when peepdf is executed:
-f: Ignores the parsing errors. Analysing malicious files propably leads to parsing errors, so this parameter should be set.
-l: Sets the loose mode, so does not search for the endobj tag because it's not obligatory. Helpful with malformed files.
* Simple execution
Shows the statistics of the file after being decoded/decrypted and analysed:
python peepdf.py [options] pdf_file
* Interactive console
Executes the interactive console to let play with the PDF file:
python peepdf.py -i [options] pdf_file
If no PDF file is specified it's possible to use the decode/encode/js*/sctest commands and create a new PDF file:
python peepdf.py -i
* Batch execution
It's possible to use a commands file to specify the commands to be executed in the batch mode. This type of execution is good to automatise analysis of several files:
python peepdf.py [options] -s commands_file pdf_file
** Updating **
Just type this and you will be updated to the latest version from the repository:
python peepdf.py -u
** Some hints **
If the information shown when a PDF file is parsed is not enough to know if it's harmful or not, the following commands can help to do it:
* tree
Shows the tree graph of the file or specified version. Here we can see suspicious elements.
* offsets
Shows the physical map of the file or the specified version of the document. This is helpful to see unusual big objects or big spaces between objects.
* search
Search the specified string or hexadecimal string in the objects (decoded and encrypted streams included).
* object/rawobject
Shows the (raw) content of the object.
* stream/rawstream
Shows the (raw) content of the stream.
* The rest of commands, of course
