Rule files of some use to us, and perhaps some scripts

In particular @thatguy31415 is working on a collection of rules to categorize files by capabilities, with inspiration from's marvelous example in Chapter 4 of the Malware Analyst Cookbook, carried from Google Code into GitHub by @yararules, and shipped in @lennyzeltser's @REMnux (seriously, the MD5 hashes match).


  • some simple yara rules that hit on imported libraries and function calls (CAP_something)
  • a batch processing Volatility script or two (eg for SIFT)
  • other sample yara rules, such as for PE module
  • a sed script for cleaning up VBA code syntax
  • OpenIOC examples, such as for Trickbot patterns reported by @hasherazade


  • [.] Win32 Inet CAP yara rule : string match works
    • needs ordinal detection, which will require yara++ and pe module
  • [.] Win32 crypto CAP yara rule : string match works
    • needs ordinal detection, which will require yara++ and pe module
  • Ransomware strings CAP yara rule
    • cryptocurrency help sites?
  • DotNet CAP yara rule
    • DotNet doesn't use PE header so much
  • [.] OpenIOC sample rules, but see some caveats

Volatility batch scripts

Header explains

### Volatility semi-automated memory image processing, for WinXP images
### bsk for, Copyleft MIT License :
### Requirements: SIFT 3 or volatility 2.5.x ; pictures needs PIL and dot available
### Run volatility framework anlaysis plugins against a provided image in an opinionated order
###     0) Quick pass to list processes and connections, 1)long run of many plugins with simple args, 
###     2) long run of complex plugins; 3)make pictures
### Ref: FOR508, Art of Memory Forensics, Malware Analyst Cookbook


### TODO  
## BUGFIX: Set out location to . if env var not set
## FEATURE: document how to branch -2
## FEATURE: Pull volatility version rather than static string
## FEATURE: if file exists and is greater than sizeof(vol usage error), skip the plugin ?
## FEATURE: tidy malsysproc extra linefeeds ?
## WISHLIST: find a way to use the ssdeep, baseline community plugins 
## WISHLIST perf : Specify kdbg offset?
## WISHLIST: duplicate image file to run plugins in parallel for faster results / test this more
## WISHLIST: port to BAT for Windows or BETTER python for crossplatform
