atomic-red-team VS PowerSploit

You can write your own or look at testing tools like Cytest to ensure that your business goals are met and to ensure your sensors are configured correctly, and ART for attack chains.

I had heard that Falcon Overwatch has a detection for Exfiltration for C2, but I was not able to trigger it using my personal Kali Machine to host a C2 server with https://github.com/cedowens/SimpleC2_Server and then used Atomic Red Team: https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1041/T1041.md

Yup what the above said, you can use atomic red https://github.com/redcanaryco/atomic-red-team

Atomic red team have tests that should trigger it, it also has a clear description of what it does and how to clean up afterwards. https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/T1059.001/T1059.001.md suggest that you try obfuscation or cradle.

Dated but still full of goodness. https://github.com/redcanaryco/atomic-red-team/tree/e88a1ea463964839e267dba74ec1cf7bf634ccbf/ARTifacts/Initial_Access

Are you familiar with Atomic Red Team? Many quick & practical sample tests you can often run without much effort or prep work. All tests map to Techniques - a quick way to search through them all at the Tactic level is by searching within the CSV index of all their current tests here (I counted ~50 Collection-related tests just now): https://github.com/redcanaryco/atomic-red-team/blob/master/atomics/Indexes/Indexes-CSV/index.csv

The correct thing to do was importing the Recon.psm1 module, as instructed in the PowerSploit's documentation.

I joined one of the clients to the domain, then downloaded powerview.ps1 from https://github.com/PowerShellMafia/PowerSploit/blob/master/Recon/PowerView.ps1).

You can grab PowerSploit . Most of the scripts will trigger powershell's Antimalware Scan Interface (AMSI) if you have real-time protection enabled. To be sure, use Invoke-Mimikatz.ps1 as AMSI blocks certain keywords like “invoke-mimikatz” or “amsiutils” since they are widely known to be used for exploitation. So I suggest you use them. Note that you can hide some malicious scripts by running an amsi bypass, thats for another day.

PowerSploit

Because the SYSVOL share is open to Authenticated Users, any user in the organization can read the files stored there. Therefore, any user account can find and decrypt the Group Policy file and thereby gain access to the plaintext passwords for Administrator accounts. The PowerSploit command Get-GPPPassword will find and decrypt these passwords for you.

Please see PowerShellMafia/PowerSploit for more information about how to run an EXE from the memory. Find examples here: GitHub Examples

Get-NetUser command of PowerSploit

The first step is to find out what trusts exist. There are several ways to do this, but two we will leverage through PowerShell are the PowerSploit framework and the Active Directory PowerShell module.

Short answer; yes. See PowerUp.ps1: https://github.com/PowerShellMafia/PowerSploit/blob/master/Privesc/PowerUp.ps1
