For QuickSand Version 2 written in Python with PDF analysis support, see quicksand.io.
QuickSand Version 1 Lite is no longer being actively developed.
QuickSand is a compact C framework to analyze suspected malware documents to 1) identify exploits in streams of different encodings, 2) locate and extract embedded executables. By having the ability to locate embedded obfuscated executables, QuickSand could detect documents that contain zero-day or unknown obfuscated exploits.
File Formats For Exploit and Active Content Detection
- doc, docx, docm, rtf, etc
- ppt, pptx, pps, ppsx, etc
- xls, xlsx, etc
- mime mso
- eml email
File Formats For Executable Detection
- All of the above, plus PDF.
- Any document format such as HWP.
