Here is a list of all articles and presentations I've published about IT Security so far.
This is a series of articles about file formats and related security issues. In 2003 I had presented an article in French about this subject at the SSTIC conference: [SSTIC03]. In the following articles I will provide an updated version in English with more information about common file formats.
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.
python-oletools is a package of python tools to analyze Microsoft OLE2 files (also called Structured Storage, Compound File Binary Format or Compound Document File Format), such as Microsoft Office documents or Outlook messages, mainly for malware analysis and debugging. It is based on the OleFileIO_PL parser.
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.
This article describes the Microsoft Office legacy/binary file formats (doc, xls, ppt), related security issues and useful resources. [WORK IN PROGRESS]
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.
This article describes the PDF file format, related security issues and useful resources. [WORK IN PROGRESS]
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.
