Volatility Bash Script v0.4

Here is another version of the volatility bash script.

#!/bin/bash
# Script to collect information by utilizing volatility

# v0.4 - Added a loop to iterate through the plugins
#      - Added svcscan, sockets, sockscan, driverscan, cachedump, timeliner, evtlogs
#      - In hivelist the system file is upper or lower case depending on the profile
#      - Added dlllist for each process
#      - Added getsids for each process
#      - Added handles for each process
#      - Added ldrmodules for each process
#      - Extracting the contents of the registry at Software\Microsoft\Windows\CurrentVersion\Run
# v0.3 - Updated to include mftparser
#      - Added a temp directory
# v0.2 - Updated the DKOM section to include the 3 columns and not just the 1st.

#To come...
#Analyze specific registry keys that aide in an investigation

Volatility - Follow-up Analysis Script - Customize the script

You need to customize the following script based on the information gathered from the analysis.

#!/bin/bash
# Script to collect information by utilizing volatility

#### Configurable Options #######

memImage="$homeDir/image.vmem"
locVolPy='/usr/share/volatility/vol.py'
