TCP. These are particularly useful in cases where a machine that you compromise cannot
reach your Team Server directly over HTTP.
To create an HTTP listener, go to Cobalt Strike > Listeners and a new tab will open. Click
the Add button and a New Listener dialogue will appear. Select Beacon HTTP as the
payload type and enter a descriptive name. This listener name is used in several Beacon
commands (such as when moving laterally), so make sure it describes the listener well.
Click the + button next to HTTP Hosts which should autocomplete to the Kali IP address
(10.10.5.120). This is fine, so click OK. Leave everything else as it is and click Save.

, 5. Generating Payloads:
To generate a payload for this listener, go to Attacks > Packages > Windows Executable (S).
Cobalt Strike is able to generated both staged and stageless payloads. Whenever you see
(S) within the Ul,it's an indication that it's using a stageless payload.
OPSEC: Staged payloads are good if your delivery method limits the amount of data you
can send. However,they tend to have more indicators compared to stageless. Given the
choice, go stageless.
Select the HTTP listener created previously, select Windows EXE as the output and tick Use
x64.
OPSEC: The use of 64-bit payloads on 64-bit Operating Systems is preferable to using 32-bit
payloads on 64-bit Operating Systems.
