 Collateral Damage is a kernel exploit for Xbox SystemOS using [CVE-2024-30088](https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-30088).
 It targets Xbox One and Xbox Series consoles running kernel versions 25398.4478, 25398.4908, and 25398.4909. The initial entrypoint is via the Game Script UWP application.

 ## Important Caveats
-This initial release is largely intended for developers. Currently a way to place files into the `LocalState` directory of Game Script is required via an app such as [Adv File Explorer (FullTrust)](https://apps.microsoft.com/detail/9nbnjpsxfsqb). 
-This is due to the requirement of placing the `stage2.bin` and `run.exe` files onto into the `LocalState` directory. In the near future a payload will be supplied which will load those files over the network, so the initial payload will simply be 
-a script which can be inputted via a USB keyboard emulator.
+
+To place the payload locally on the Xbox console a full-trust explorer like [Adv File Explorer (FullTrust)](https://apps.microsoft.com/detail/9nbnjpsxfsqb) is recommended. Alternatively, the initial payload can be served via a USB keyboard simulator (rubber ducky etc.) and further payload stages can then be loaded over the network.
 
 The reverse shell example provided here requires that your console is connected to a network. When connecting your console to a network be very careful to avoid connecting to the internet and updating. Try to block connectivity to Xbox LIVE as 
 much as possible, at the very least by setting your DNS to invalid servers.

 This exploit is not fully reliable. It relies on a CPU side channel as well as a race condition, both of which have the potential to fail. In the event of a failure, the exploit may alert you that it has failed via network output, or the console itself may crash and reboot.
 
 ## Usage
-- Modify line 7 of `gamescript_autosave.txt` to contain the local IP of your PC.
-- Copy `gamescript_autosave.txt`, `stage2.bin`, and `run.exe` to the `LocalState` directory of the Game Script application on your Console (`Q:\Users\UserMgr0\AppData\Local\Packages\27878ConstantineTarasenko.458004FD2C47C_c8b3w9r5va522\LocalState\`)

+- Modify line 7 of `gamescript_autosave_network.txt` or `gamescript_autosave.txt` to contain the local IP of your PC.
+  - For use with Full-Trust File Explorer App: Copy `gamescript_autosave.txt`, `stage2.bin`, and `run.exe` to the `LocalState` directory of the Game Script application on your Console (`Q:\Users\UserMgr0\AppData\Local\Packages\27878ConstantineTarasenko.458004FD2C47C_c8b3w9r5va522\LocalState\`)
+  - For HID / Keyboard simulator input: Type the contents of `gamescript_autosave_network.txt` into the GameScript window. Serve `stage2.bin` and `run.exe` via `payload_server_win_x64.exe --stage2 stage2.bin --run run.exe`
 - Listen on port 7070 on your PC using netcat or a similar tool (command example: `nc64.exe -lvnp 7070`)
 - Open the Game Script application on your console and select "Show Code Run window" and click "Run code once"
 - If the exploit is success you should see output on your PC that resembles the following:
