peepdf is a Python 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.
- 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
- Modifications between versions (changelog)
- Compressed objects (object streams)
- Shellcode analysis (sctest wrapper, Libemu)
- Variables (set command)
- Extraction of old versions of the document
- Basic PDF creation
- 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
With all the recent PDF security scares and PDF hacking it’s important to have adequate tools for PDF analysis.
