Injecting lua code in working VTF files and then running it
[char* secret_key, int64 offset] mat_payload.WriteCodeToVTF(char* identifier, char* lua_code, [optional] char* vtf_to_inject)
identifier is the name of the vtf, no extension needed, it will go in data/
lua code is the payload, ASCII ONLY, no UTF8.
vtf_to_inject if you want to use a vtf as a base to make it less suspiscious, nil for empty vtf (65 bytes iirc)
Returns :
secret_key the generated key to "obfuscate the code", needed to read the code, i return it to allow you to automatize stuff
offset offset of the payload, same reason as above
It allows you to run stuff like :
local func = mat_payload.ReadCodeFromVTF("garrysmod/data/skybox_item_10_tmp.vtf", mat_payload.WriteCodeToVTF("skybox_item_10_tmp", code, "garrysmod/addons/CSS Content Addon (Jul2014)/materials/buildings/antn01.vtf"))
Il also prints a message in the console giving you the key to read it and the offset from where the payload starts
void* mat_payload.ReadCodeFromVTF(char* path, char* key, int64 offset)
path BASE_PATH path of the file to read the payload from
key key to read the payload
offset where the payload starts
Example lua code
All paths are in BASE_PATH context
require("mat_payload")
local code = [[
print'yolahahaha hello from a vtf file'
print'this is sparta'
player.GetByID(1):Kill()
print(SysTime())
]]
mat_payload.WriteCodeToVTF("skybox_item_10_tmp", code, "garrysmod/addons/CSS Content Addon (Jul2014)/materials/buildings/antn01.vtf")
--Wrote to file : [garrysmod/data/skybox_item_10_tmp.vtf] with secret key "68124168458642", and VTF offset is 87600, SAVE ALL OF THESE INFORMATIONS
local func = mat_payload.ReadCodeFromVTF("garrysmod/data/skybox_item_10_tmp.vtf", "68124168458642", 87600)
