This article explains how I converted Signsrch signatures to Yara rules, in order to include them in my tool Balbuzard. Signsrch signatures are useful for malware analysis, to detect standard constants used in many encryption and compression algorithms, and also some anti-debugging code.
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.

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.
