The powershell-import command will import a PowerShell script into Beacon. The psinject command will inject Unmanaged PowerShell into a specific process and run your cmdlet from that location. The powershell and powerpick commands will use your current token. This command relies on the Unmanaged PowerShell technique developed by Lee Christensen. Use the powerpick command to execute PowerShell cmdlets without powershell.exe. Use the powershell command to execute a command with PowerShell on the compromised host. The execute command runs a program in the background and does not capture output. Use the run command to execute a command without cmd.exe. When the command completes, Beacon will present the output to you. You must make your Beacon interactive before you tunnel traffic through it.Ī few Beacon commands (e.g., browserpivot, desktop, etc.) will automatically put Beacon into interactive modeīeacon's shell command will task a Beacon to execute a command via cmd.exe on the compromised host. In this modeĬommands will execute right away. To make a Beacon check in multiple times each second, try sleep 0. This means, Beacon will sleep for a random value between 240s to For example, sleep 300 20, will force Beacon to sleep forģ00 seconds with a 20% jitter percentage. Random percentage you specify as a jitter factor.

Beacon will vary each of its check in times by the Use sleepįollowed by a time in seconds to specify how often Beacon should check in. You may change this with Beacons sleep command. If you make a mistake, use the clearĬommand to clear the command queue for the current Beacon.īy default, Beacons check in every sixty seconds. At this time, Beacon will also report any output it has for you.

When the Beacon checks in (connects to you), it will download these commands and execute them one by Asynchronous and Interactive Operationsīe aware that Beacon is an asynchronous payload. Most actions that happen through this menu will apply to all selected Beacon sessions. Some of Cobalt Strike's visualizations (the pivot graph and sessions table) let you select multiple BeaconsĪt one time. Where you manage the current Beacon session. The Pivoting menu is where you can setup tools to tunnel traffic through a Beacon. The Explore menu consists of options to extract information and interact with the target’s The Access menu contains options to manipulate trust material and elevate Right-click on a Beacon or inside of a Beacon's console to access the Beacon menu. Type helpįollowed by a command name to get detailed help. Type help in the Beacon console to see available commands. It’s worth your time toīecome familiar with its commands. You will likely spend most of your time with Cobalt Strike in the Beacon console. If a teammate issues a command, Cobalt Strike will pre-fix the command with their handle. Username and PID of the current session, and the Beacon’s last check-in time.Įach command that's issued to a Beacon, whether through the GUI or the console, will show up in this In its default configuration, the statusbar shows the target's NetBIOS name, the This status bar contains informationĪbout the current session.

In between the Beacon console's input and output is a status bar. The Beacon console is also where command output and other The Beacon console allows you to see which tasks were issued to aīeacon and to see when it downloads them. Right-click on a Beacon session and select interact to open that Beacon's console.

This allows you to cloak Beacon activity to look like other malware or blend-in as legitimate traffic. Redefine Beacon's communication with Cobalt Strike's Interactive communication happens in real-time.īeacon's network indicators are malleable. Will phone home, download its tasks, and go to sleep. Asynchronous communication is low and slow.

You mayĪlso limit which hosts egress a network by controlling peer-to-peer Beacons over Windows named pipes.īeacon is flexible and supports asynchronous and interactive communication. Use Beacon to egress a network over HTTP, HTTPS, or DNS. Beacon is Cobalt Strike's payload to model advanced attackers.
