This is not necessary with Cobalt Strike. Many post-exploitation actions fail otherwise.

It helps to match Meterpreter’s architecture to the native architecture of your Windows target. Credentials are available under View -> Credentials. The mimikatz command will run arbitrary mimikatz commands. Type logonpasswords to harvest credentials with mimikatz.

Once you elevate, use hashdump to recover local account password hashes. PowerUp works well with Beacon’s powershell and powerpick commands. The spawnas command will let you use known credentials to spawn a session as another user.
Use this if your user is a local admin, but you’re in a medium integrity context. The bypassuac command runs the Bypass UAC attack. Privilege EscalationĬobalt Strike has a few options to aid privilege escalation.
These windows will auto-update when there is new data. If you take screenshots or log keystrokes, be aware that Cobalt Strike presents these under View -> Screenshots and View -> Keystrokes. Highlight one or more files in this dialog and press Sync Files to bring files to your local system. Go to View -> Downloads to see downloaded files. Downloaded files are stored on the team server.

Use the download command to download files. Use the inject command to inject a Beacon into an x86 or 圆4 process. Many post-exploitation tasks (e.g., screenshot, keylog) will inject into a process you specify and feed results back to your Beacon. Migrateīeacon does not have a migrate command. The powerpick command does the same thing, but without powershell.exe. Use the powershell command to evaluate your imported script and run the cmdlet and arguments you specify. This command does not execute or check the script. The powershell-import command imports a local PowerShell script into Beacon. The shell command will run the command you specify with cmd.exe and present its output to you. Don’t put quotes around the folder name (even if there are spaces). The cd command changes Beacon’s current working directory. Type help and a command name to get more information on a command. Meterpreter users will feel at home with Beacon. Your Malleable C2 profile sets the default sleep time. In between check-ins, Beacon goes to sleep. When the agent checks in, Beacon downloads them, and executes them in order. This means commands you type will not execute right away. Asynchronous Post Exploitationīeacon is an asynchronous agent. When you get an access, right-click on it and press Interact. I recommend setting PrependMigrate to True as well. So long as you match stagers, this process should work. Cobalt Strike is compatible with Metasploit’s staging protocol. Pick a Windows exploit, point LHOST and LPORT at your listener, and set PAYLOAD to windows/meterpreter/.
Optionally, you may use a Metasploit Framework exploit to deliver Beacon. This is the payload the attack will deliver. Each of these features ask you to choose a listener. These options exist under Attacks -> Packages and Attacks -> Web Drive-by. User-driven AttacksĬobalt Strike has several user-driven attack options to get a foothold in a target Cobalt Strike has tools to help with the targeted attack process. It’s my assumption that you either have a foothold, through another means, or that you will gain one through a targeted attack. “where are the exploits?” “how do I scan targets?” “how do I get that first Beacon on target?” Cobalt Strike is designed for engagements where you work as an external actor. Once a listener is setup, Cobalt Strike’s team server is listening for connections. You will want to read the documentation before you try out the DNS Beacon. The HTTP and HTTPS Beacon are straight forward to configure. Fill in the information for your team server host. teamserver ListenersĬobalt Strike refers to its payload handlers as listeners. Specify the profile you want to use when you run your team server: $. I do not recommend that you use Cobalt Strike with the default profile. Malleable ProfilesĬobalt Strike supports a concept of user-defined network indicators in its Beacon payload. Launch the client, put your name in the user field, set everything else properly and press Connect. The Windows, Linux, and MacOS X packages for Cobalt Strike include a launcher to start the client. The team server must run on Linux with Java installed. Starting Cobalt StrikeĬobalt Strike ships as a client program and a server program. This post does not replace the documentation or videos, but it’s a quick way to become familiar with Cobalt Strike concepts that are not immediately obvious. I assume that you are familiar with Meterpreter, Mimikatz, and make use of Offensive PowerShell in your work. This blog post is a fast overview of Cobalt Strike.
