File Scanning Frameworks for Malware Analysis and Incident Response

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.

How to convert Signsrch/Clamsrch signatures to Yara

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 - malware analysis tools to extract patterns of interest and crack obfuscation such as XOR

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.

PDF Security Issues

This article describes the PDF file format, related security issues and useful resources. [WORK IN PROGRESS]

pyxswf - a python tool to extract SWF (Flash) objects from documents (improved xxxswf)

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 - a python tool to extract embedded objects from RTF files

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 - a python tool to quickly analyze OLE files

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 - a simple python GUI to browse OLE files and extract streams

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 - a Python module to parse MS Word forms (docx) to extract field values and tags

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 - a python library to create, parse and edit IODEF incident reports

iodeflib is a python library to create, parse and edit cyber incident reports using the IODEF XML format (RFC 5070).
