There are 3 common ways to inject a binary into a system - either by downloading it from the network, copying it over mass storage, or typing the program code right into the computer. Previously we had shown ways of obtaining a reverse shell from a target computer by injecting a netcat binary into the computer. When it receives the connection it is then able to execute commands on the victim computer. After that, I added the following line to the payload file which will invoke the introduced function and connect the meterpreter.The attacking computer typically listens on a specific port. When talking about payload here, all it really is is a file that will be made available via HTTP for the powershell script to download. This will go into the payload that needs to be downloaded to bring the meterpreter up. Ibew local 3 pay scaleĪs already mentioned, I was going to use Invoke-Shellcode.

Together these will download the hosted payload and prepare the meterpreter. A payload which includes the Invoke-Shellcode. In essence, getting the meterpreter shell up required 2 things apart from the command execution.

Admittedly, I have never actually done this so a little Google-fu and research was needed to get it working right, but eventually this payed off. So, next on the list? I could just make use of Invoke-Shellcode. Some investigations showed though that the AV on the box was killing the meterpreter. For this reason, reaching out for a meterpreter shell is almost a knee-jerk reaction.

On Windows based environments though, the builtin cmd. 06 - The PowerShell in the shell: remoting Getting an interactive shell on linux based hosts was as simple as picking your favorite flavor of reverse shell and moving on from there. Remember, I was able to do this without any authentication requirement! To help with testing, I setup a local instance of the latest Jenkins v1. The documentation goes into enough detail explaining the different options you have to execute commands, but the above snippet was enough to get going. In fact, the syntax was quite expressive as explained in the documentation. Some research revealed that it is actually possible to execute commands using it. Poking around through the web interface eventually got me to the Script Console that Jenkins provides. At first glance I was not too sure about what opportunities I was presented with when finding this. In fact, it seems like its almost plug and play. Right out of the box Jenkins does not require any authentication to make use of it. A relatively old version I might add but that fact was not important. If you want to give quick and simple feedback on this doc.Recently I came across a few Jenkins continuous integration servers. If you would like to suggest an improvement to this doc.
