oletimes is a script to parse OLE files such as MS Office documents (e.g. Word, Excel), to extract creation and modification times of all streams and storages in the OLE file. It is part of the python-oletools package.
olemeta is a script to parse OLE files such as MS Office documents (e.g. Word, Excel), to extract all standard properties present in the OLE file. It is part of the python-oletools package.
Since version 0.32, OleFileIO_PL comes with experimental write features. For now it is possible to write sectors, and to write over an existing stream. More features will be added over time.
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.
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.
This article describes the PDF file format, related security issues and useful resources. [WORK IN PROGRESS]
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.
