Spring Training 2016 - Analysing Malicious Documents
From BruCON 2016
Analysing Malicious Documents
PDF exploits and malicious PDF documents have been on the radar for several years now. Together with MS Office files like Word and Excel documents. But do you know how to detect them? And how they are constructed?
This training will teach you how to analyse PDF files and MS Office files (both “old” OLE and “new” XML formats). PDF files that execute code via exploits. MS Office documents that execute code via macros or exploits. Didier Stevens will teach you how to use his Python tools to analyse PDF documents and MS Office documents.
Didier’s Python tools also use YARA rules to detect shellcode or other indicators of executable code. Didier will explain his YARA rules, and teach you how to tweak them and build your own.
Attendees will receive a personal license to Didier Stevens Labs’ “PDF Workshop” videos.
To get a better idea of the training, you can also view the following YouTube videos Didier produced:
- Deep understanding of the Portable Document Format
- Analysis of (malicious) PDF files
- Deep understanding of the OLE (CBF) file format
- Deep understanding of Microsoft’s Office Open XML format
- Analysis of (malicious) MS Office files
- Introduction to the PDF language
- Identification of PDF files with pdfid
- Analysis of PDF files with pdf-parser (20 custom designed exercises)
- Analysis of real malicious PDF files found “in the wild”
- Introduction to the OLE (CBF) file format
- Introduction to Microsoft’s Office Open XML format
- Analysis of MS Office files with oledump (30 custom designed exercises)
- Analysis of real malicious MS Office files found “in the wild”
This training is for technical IT security professionals like analysts and incident responders, but also for interested hackers. Be familiar with command line tools.
- A Windows laptop is preferred, although the Python tools pdfid, pdf-parser and oledump also work on OSX and Linux
- Administrative rights
- Rights to disable AV
