DAMM – Differential Analysis of Malware in Memory


Differential Analysis of Malware in Memory (DAMM) is a tool built on top of Volatility Framework. Its main objective is as a test bed for some newer techniques in memory analysis, including performance enhancements via persistent SQLite storage of plugin results (optional); comparing in-memory objects across multiple memory samples, for example processes running in an uninfected samples versus those in an infected sample; data reduction via smart filtering (e.g., on a pid across several plugins); and encoding a set of expert domain knowledge to sniff out indicators of malicious activity, like hidden processes and DLLs, or windows built-in processes running form the wrong directory.

DAMM - Differential Analysis of Malware in Memory

It is meant as a proving ground for interesting new techniques to be made available to the community. These techniques are an attempt to speed up the investigation process through data reduction and codifying some expert knowledge.

Features

  • ~30 Volatility plugins combined into ~20 DAMM plugins (e.g., pslist, psxview and other elements are combined into a ‘processes’ plugin)
  • Can run multiple plugins in one invocation
  • The option to store plugin results in SQLite databases for preservation or for “cached” analysis
  • A filtering/type system that allows easily filtering on attributes like pids to see all information related to some process and exact or partial matching for strings, etc.
  • The ability to show the differences between two databases of results for the same or similar machines and manipulate from the cmdline how the differencing operates
  • The ability to warn on certain types of suspicious behavior
  • Output for terminal, tsv or grepable

Usage

Most DAMM output looks better piped through ‘less -S’ (upper ‘S’) as in:


Warnings

In an attempt to make the triage process even easier, DAMM has an experimental warning system built in to sniff out signs of malicious activity including:

For certain Windows processes:

  • incorrect parent/child relationships
  • hidden processes
  • incorrect binary path
  • incorrect default priority
  • incorrect session

For all processes, and loaded DLLs and modules:

  • loaded/run from temp directory

For DLLs:

  • bogus extensions
  • hidden DLLs

Plus more!

  • PE headers in injections
  • SIDs giving domain access
  • debug privileges …

See the warnings.py file for much more information on what DAMM checks for.
