CobaltStrike environment construction and client connection server

CobaltStrike is a very powerful tool, similar to MSF, but with more powerful functions.
First of all, after the CobaltStrike file package is downloaded, the server side is only supported in the Linux system. At the same time, this tool requires a java environment. The official recommendation is for everyone to use it, but I installed the simple openjdk-8-jdk in ubuntu for convenience. :
Java installation steps: 1. First update the source, command sudo apt-get update
2.java -version (if you have it, you don’t need to install it, if you don’t have it, there will be installation options below)
3.sudo apt-get install openjdk-8- jdk (enter Y in the middle step) The
Java environment is installed.
Start the server side of CobaltStrike:
1. In the file directory, enter the command: ./teamserver+ip+password
Note: If you can’t start it, it may be a permission problem, just modify the permission. : Chmod 777 ./teamserver
or the java environment does not support

2. Use VPS (client) to connect to the server
Use the start.sh in the folder to open the

box, only need to modify the host to the server-side ip address, and the port 50050 is fixed No change, the user name can be whatever you want, and the password must be written as the server-side password. At

this time, you should pay attention to whether your 50050 port is open.

When the connection is successful, a string of numbers is the same as the one given by the server, indicating that the secret key is used to match the connection between the client and the server.

You can see that you have successfully logged in without going through a third party
