Switch to the Windows host and prepare the UUID runner to run our Beacon payload.

Since the Cobalt Strike Beacon uses the Reflective DLL Loading technique, the shellcode will execute the beacon when it is ran on an Intel 圆4 processor within a Windows OS.

The Raw payload will save our Stageless Beacon as pure shellcode.

Select the http listener we just created.

A Staged payload will likely be detected.

The Staged loader used in Cobalt Strike is flagged.

A Stageless payload has the entire beacon in it, while the Staged version only has a small stub that calls out to the teamserver and then loads the rest of the beacon.

The (S) means that the payload will be Stageless.

From the CobaltStrike GUI, click Attacks from the menu bar, then Packages, and select Windows Executable (S).

Create a 64-bit Stageless Cobalt Strike beacon shellcode payload.

When the beacon listener is the way you want it, click Save.

For the HTTP Hosts, click the + button and add the teamservers IP.

Select your beacon type, such as BeaconHTTP used in this example.

From the listeners table, click the Add button.

This will display the active listeners in a table, on the bottom half of the CS GUI.

From the CobaltStrike GUI, click Cobalt Strike from the menu bar, and then select Listeners.

Create a Listener that our stageless beacon payload will connect to, when it is executed on the windows host.

In the CRTO labs, cobaltstrike is located in the /opt/ directory, but this may differ based on your installation.

Start your Cobalt Strike teamserver & the cobaltstrike gui on the Kali-Attacker box.

Since I think these labs are awesome, this walkthrough shows how to get this project working in the CRTO lab environment! Cobalt Strike Stageless Beacon Walkthrough What we can do, is copy-paste text from our host to the the CRTO lab. Another hurdle is we cannot copy entire files to and from our CRTO lab. Since the CRTO labs have Cobalt Strike, for security reasons they are not connected to the public internet. If you are interested in digging deeper into Cobalt Strike, I definitely recommend getting your hands dirty with this course! This was tested in the new Certified Red Team Operator course labs which gives you Cobalt Strike access out-of-the-box.
