peepdf3 4.0.0

peepdf-3 - peepdf for Python 3
peepdf-3 is a Python 3 tool to explore PDF files in order to find out if the file can be harmful or not. The aim of this tool is to provide all the necessary components that
a security researcher could need in a PDF analysis without using 3 or 4 tools to make
all the tasks.
With peepdf it's possible to see all the objects in the document showing
the suspicious elements, supports all the most used filters and encodings, it can parse different versions of a file, object streams and encrypted files. With the installation
of STPyV8 and Pylibemu it provides Javascript and shellcode analysis wrappers too. Apart of this it's able to create new PDF files and to modify/obfuscate existent ones.
As of version 3.0.0, peepdf-3 no longer includes pylibemu as a requirement in order to use peepdf-3 on Windows systems. However, all functionality of libemu, pylibemu, and sctest still exist, and will function on Linux systems.

Features
The main functionalities of peepdf are the following:
Analysis:

Decodings: hexadecimal, octal, name objects
More used filters
References in objects and where an object is referenced
Strings search (including streams)
Physical structure (offsets)
Logical tree structure
Metadata
Modifications between versions (changelog)
Compressed objects (object streams)
Analysis and modification of Javascript (STPyV8): unescape, replace, join
Shellcode analysis (Libemu python wrapper, pylibemu)
Variables (set command)
Extraction of old versions of the document
Easy extraction of objects, Javascript code, shellcodes (>, >>, >,>>)
Checking hashes on VirusTotal
Detection of common encryption methods
Output of XML and JSON data

Creation/Modification:

Basic PDF creation
Creation of PDF with Javascript executed wen the document is opened
Creation of object streams to compress objects
Embedded PDFs
Strings and names obfuscation
Malformed PDF output: without endobj, garbage in the header, bad header...
Filters modification
Objects modification

Ways to use peepdf:

Basic execution
Interactive console
Script mode
JSON Output
XML Output
VirusTotal analysis
