Kansa

A modular incident response framework in Powershell.

##What does it do? It uses Powershell Remoting to run user contributed, ahem, user contri-
buted modules across hosts in an enterprise to collect data for use
during incident response, breach hunts, or for building an environmental
baseline.

##How do you use it? Here's a very simple command line example you can run on your own local
host.

After downloading the project and unzipping it, you'll likely need
to "unblock" the ps1 files. The easiest way to do this if you're using
Powershell v3 or later is to cd to the directory where Kansa resides
and do:

ls -r *.ps1 | Unblock-File

If you're not running PS v3 or later, Sysinternal's Streams utility can
be used to remove the alternate data streams that Powershell uses to
determine if files came from the Internet. Once you've removed those
ADSes, you'll be able to run the scripts without issue.

I've not run into any issues running the downloaded scripts via Windows
Remote Management / Powershell Remoting through Kansa, so you shouldn't
have to do anything if you want to run the scripts via remoting.

Open an elevated Powershell Prompt (Right-click Run As Administrator)
At the command prompt, enter:

.\kansa.ps1 -Target localhost -ModulePath .\Modules -Verbose

The script should start collecting data or you may see an error about
not having Windows Remote Management enabled. If so, do a little
searching online, it's easy to turn on. Turn it on and try again. When
it finishes running, you'll have a new Output_timestamp subdirectory,
with subdirectories for data collected by each module. You can cd into
those subdirectories and checkout the data. There are some analysis
scripts in the Analysis directory, but many of those won't make sense
on a collection of data from a single host. Kansa was written for
collection and analysis of data from dozens, hundreds, thousands, tens
of thousands of systems.

##Running Modules Standalone Kansa modules can be run as standalone utilities outside of the Kansa
framework. Why might you want to do this? Consider netstat -naob, the
output of the command line utility is ugly and doesn't easily lend
itself to analysis. Running

Modules\Net\Get-Netstat.ps1

as a standalone script will call netstat -naob, but it will return
Powershell objects in an easy to read, easy to analyze format. You can
easily convert its output to CSV, TSV or XML using normal Powershell
cmdlets. Here's an example:

.\Get-Netstat.ps1 | ConvertTo-CSV -Delimiter "`t" -NoTypeInformation | % { $_ -replace "`"" } | Set-Content netstat.tsv

the result of the above will be a file called netstat.tsv containing
unquoted, tab separate values for netstat -naob's ouput.

##Caveats: Powershell relies on the Windows API. Your adversary may use subterfuge.*

Collectors can be written to bypass the Windows API as well.
Get-RekallPslist.ps1 for example.
