I've done small amounts of p2c work and been coding private/personal projects for around 4 years now, due to a loss of interest I've cleaned up the code to my RWX injector and wanting to sell it's source. It's been tested and used on BE/EAC (and used by a couple irl friends) for 6 months now. Due to my injection method I assume it will work on Vanguard too but I haven't done any testing on it as I don't map my driver at boot. The whole injection process will work on any game, and comes with support for any game by default - Vanguard included providing you have a method to map your driver before the anticheat. I'm also happy if a trusted middleman is needed when purchasing.
Games I've tested my cheats with using the injector: Escape From Tarkov, Rainbow Six: Siege, Squad, Fortnite.
On these games I haven't gotten any bans within the 6 months of use.
If you are wanting to buy the whole package (RWX dll, usermode + driver) it will only work on windows versions 2004+ as my communication method is using a private, temporary .data ptr hook that is unhooked after injection and before any detection routines are run. Due to the way I've coded the injector its easy enough to swap the driver to your own. At no point are there any patches placed on the game and there is no memory allocated during the injection. After injection there are no traces left behind. And for anyone familiar with RWX injection, I am not using SetWindowsHookEx.
If you are interested we can talk over PM and I'll provide my discord account, in discord I'm happy to provide more information on the injection process and proof of it working - for purchases I prefer taking crypto, however other methods can be discussed over discord. I can provide the RWX dll and usermode as a standalone and allow you to use your own driver along with it however a decent portion of functionality is done through the driver.
