|
||||
This module allow to inject your shellcode in a host process.
|
||||
You can decide if inject into an existing process or if spawn a new process as a host process for the code.
|
||||
You should create the payload for the shellcode from msfvenom with the flag --format csharp.
|
||||
You can use one of the following supported injection technique:
|
||||
- remove_virtual: classic injection:
|
||||
VirtualAllocEx (RWX) -> WriteProcessMemory -> CreateRemoteThread
|
||||
- remote_protect: with this technique you never allocate RWX memory:
|
||||
VirtualAllocEx(RW) -> WriteProcessMemory -> VirtualProtect(RX) -> CreateRemoteThread
|
||||
|
||||
Usage:
|
||||
#inject_shellcode shellcode_path [injection_type] [remote_process]
|
||||
|
||||
Positional arguments:
|
||||
shellcode_path path to a file containing shellcode in csharp format (msfvenom --format csharp)
|
||||
it can also be a bytearray string, i.e. '{0x90,0x90,0x90,0x90}'
|
||||
injection_type the process injection method to use for injecting shellcode
|
||||
Allowed values: 'remote_virtual', 'remote_virtual_protect'
|
||||
Default: 'remote_virtual'
|
||||
remote_process path to an executable to spawn as a host process for the DLL code
