This is a Beacon Object File (BOF) that executes unmanaged PEs inline and retrieves their output without allocating a console (i.e. spawning conhost.exe).
- Supports 64 and 32 bits
- Supports EXEs and DLLs
- Does not create new processes
- Saves binaries in memory
Summary: Run an unmanaged EXE/DLL inside Beacon's memory.
Usage: noconsolation [--local] [--timeout 60] [-k] [--method funcname] [-w] [--no-output] [--alloc-console] [--close-handles] [--free-libraries] /path/to/binary.exe arg1 arg2
--local, -l Optional. The binary should be loaded from the target Windows machine
--timeout NUM_SECONDS, -t NUM_SECONDS Optional. The number of seconds you wish to wait for the PE to complete running. Default 60 seconds. Set to 0 to disable
-k Optional. Overwrite the PE headers
--method EXPORT_NAME, -m EXPORT_NAME Optional. Method or function name to execute in case of DLL. If not provided, DllMain will be executed
-w Optional. Command line is passed to unmanaged DLL function in UNICODE format. (default is ANSI)
--no-output, -no Optional. Do not try to obtain the output
--alloc-console, -ac Optional. Allocate a console. This will spawn a new process
--close-handles, -ch Optional. Close Pipe handles once finished. If PowerShell was already ran, this will break the output for PowerShell in the future
--free-libraries, -fl Optional. Free all loaded DLLs
--dont-save, -ds Optional. Do not save this binary in memory
--list-pes, -lpe Optional. List all PEs that have been loaded in memory
--unload-pe PE_NAME, -upe PE_NAME Optional. Unload from memory a PE
/path/to/binary.exe Required. Full path to the windows EXE/DLL you wish you run inside Beacon. If already loaded, you can simply specify the binary name.
ARG1 ARG2 Optional. Parameters for the PE. Must be provided after the path
Example: noconsolation --local C:\windows\system32\windowspowershell\v1.0\powershell.exe $ExecutionContext.SessionState.LanguageMode
Example: noconsolation /tmp/mimikatz.exe privilege::debug token::elevate exit
Example: noconsolation --local C:\windows\system32\cmd.exe /c ipconfig
Example: noconsolation LoadedBinary.exe args
Binaries are automatically encrypted and stored in memory after they are ran the first time. This means that you do not need to constantly send the binary over the wire.
To execute a binary that has already been saved in memory, simply specify its name instead of its entire path. So, instead of running:
noconsolation --local C:\windows\system32\cmd.exe /c ipconfig
You would run:
noconsolation cmd.exe /c ipconfig
To list all binaries loaded in memory, run --list-pes.
If you are done with some binary and wish to unload it, run --unload-pe mimikatz.exe.
Finally, if you want to run a binary without it being automatically loaded in memory, run it with --dont-save.
