This article presents several new open source frameworks meant to simplify static file scanning for malware analysis and incident response: MASTIFF, Viper, IRMA and a few others. Their goal is to provide an extensible framework to integrate many existing scanning tools.
Balbuzard is a package of malware analysis tools in python to extract patterns from suspicious files (IP addresses, domain names, known file headers, interesting strings, etc). It can also crack malware obfuscation such as XOR, ROL, etc by bruteforcing and checking for those patterns.
reScan is a very simple Python script to look for specific patterns (regular expressions) in binary or text files. It has been primarily developed to analyze malicious files, to quickly extract interesting patterns (shellcodes, embedded executables in malformed documents, etc). Update in 2014: it has now evolved into Balbuzard, which provides many more features.
pyxswf is a script to detect, extract and analyze Flash objects (SWF files) that may be embedded in files such as MS Office documents (e.g. Word, Excel) and RTF, which is especially useful for malware analysis. It is part of the oletools package. pyxswf is an extension of xxxswf.py published by Alexander Hanel.
rtfobj is a Python module to extract embedded objects from RTF files, such as OLE ojects. It can be used as a Python library or a command-line tool. It is part of the oletools package.
oleid is a script to analyze OLE files such as MS Office documents (e.g. Word, Excel), to detect specific characteristics that could potentially indicate that the file is suspicious or malicious, in terms of security (e.g. malware). For example it can detect VBA macros, embedded Flash objects, fragmentation. It is part of the oletools package.
olebrowse is a simple GUI to browse OLE files (e.g. MS Word, Excel, Powerpoint documents), to view and extract individual data streams. It is part of the oletools package.
pywordform is a python module to parse Microsoft Word forms in docx format, and extract all field values with their tags into a python dictionary.
iodeflib is a python library to create, parse and edit cyber incident reports using the IODEF XML format (RFC 5070).
This article describes solutions to create a single executable file containing a Python application/script and the Python interpreter DLL with all necessary libraries. The executable file can then be launched on any system even if Python is not installed.
