A toolset to make a system look as if it was the victim of an APT attack
APT Simulator
Important: Don't just ZIP download or clone the repo if you don't plan to develop some test. Use the package in the release which contains a packaged version with encrypted archives that don't contain cleartext samples and tools.
APT Simulator is a Windows Batch script that uses a set of tools and output files to make a system look as if it was compromised. In contrast to other adversary simulation tools, APT Simulator is designed to make the application as simple as possible. You don't need to run a web server, database or any agents on set of virtual machines. Just download the prepared archive, extract and run the contained Batch file as Administrator. Running APT Simulator takes less than a minute of your time.
Use Cases
- POCs: Endpoint detection agents / compromise assessment tools
- Test your security monitoring's detection capabilities
- Test your SOCs response on a threat that isn't EICAR or a port scan
- Prepare an environment for digital forensics classes
Motives
Customers tested our scanners in a POC and sent us a complaint that our scanners didn't report on programs that they had installed on their test systems. They had installed an Nmap, dropped a PsExec.exe in the Downloads folder and placed on EICAR test virus on the user's Desktop. That was the moment when I decided to build a tool that simulates a real threat in a more appropriate way.
Why Batch?
- Because it's simple: Everyone can read, modify or extend it
- It runs on every Windows system without any prerequisites
- It is closest to a real attacker working on the command line
Focus
The focus of this tool is to simulate adversary activity, not malware. See the Advanced Solutions section for advanced tools to simulate adversary and malware activity.
Getting Started
- Download the latest release from the "release" section
- Extract the package on a demo system (Password: apt)
- Start a cmd.exe as Administrator
- Navigate to the extracted program folder and run APTSimulator.bat
Avoiding Early Detection
The batch script extracts the tools and shells from an encrypted 7z archive at runtime. Do not download the master repo using the "download as ZIP" button. Instead use the official release from the release section.
AV Excluder
APT Simulator contains a module named "AVExcluder" that tries to register the used %APTDIR%
as AV exclusion in typical AV solutions. As I do not have access to all of the AV software products in the market, please report errors or add new exclusions as pull requests.
Extending the Test Cases
Since version 0.4 it is pretty easy to extend the test sets by adding a single .bat
file to one of the test-set category folders.
E.g. If you want to write a simple test case for "privilege escalation", that uses a tool named "privesc.exe", clone the repo and do the following:
- Add your tool to the
toolset
folder - Write a new batch script
privesc-1.bat
and add it to the./test-sets/privilege-escalation
folder - Run
build_pack.bat
- Add your test case to the table and test sets section in the README.md
- Create a pull request
Tool and File Extraction
If your script includes a tool, web shell, auxiliary or output file, place them in the folders ./toolset
or ./workfiles
. Running the build script build_pack.bat
will include them in the encrypted archives enc-toolset.7z
and enc-files.7z
.
Extract a Tool
"%ZIP%" e -p%PASS% %TOOLARCH% -aoa -o%APTDIR% toolset\tool.exe > NUL
Extract a File
"%ZIP%" e -p%PASS% %FILEARCH% -aoa -o%APTDIR% workfile\tool-output.txt > NUL
Detection
The following table shows the different test cases and the expected detection results.
- AV = Antivirus
- NIDS = Network Intrusion Detection System
- EDR = Endpoint Detection and Response
- SM = Security Monitoring
- CA = Compromise Assessment

Cobalt Strike Beacon Activity
You should now be able to find events in your security monitoring solution (SIEM, EDR etc.) for the following keywords:
Named Pipes
-
MSSE-1337-server
-
msagent_fedac123
-
postex_ssh_fedac123
-
334485
(used in Get System activity)
Note: No Named Pipe Monitoring? You can use Sysmon + this config and this Sigma rule to get you started.
Get System Activity
-
b6a1458f396
(multiple events: new service registration and process creation)
Note: No events? you can use this Sigma rule to get you started.

WARNING
This repo contains tools and executables that can harm your system's integrity and stability. Do only use them on non-productive test or demo systems. Create a snapshot before you start. Otherwise you have to remove all the modifications manually, which is a tedious task.
