Assistance with "LocalizationTables"

#1

What do I want to achieve? I would like to modify a localization table to block key words that most backdoor scripts may include. (EX: “require”, “loadstring”, etc)

What is the issue? I cannot, for the life of me, find a way to block a portion of a total string. (EX: “require(123)” → “blocked(123)” or “local a = loadstring” → “local a = blocked”)

What solutions have I tried so far? I’ve looked on the Developer Hub, but alas, no luck.

I have a short local script to handle this.

local LocalizationService = game:GetService("LocalizationService")

local BlockedString = {
	"execute",'executor','exec',"r6","r15","hub","god",
	'require','getfenv','setfenv','_G','loadstring','game','getService','workspace'
}
local strs = {}
local extra = "blocked"

for i,v in BlockedString do
	table.insert(strs,v)
	table.insert(strs,v:sub(1,1):upper()..v:sub(2))
end

for i, v in pairs(strs) do
	local localTable = Instance.new("LocalizationTable")
	localTable.Parent = LocalizationService
	localTable:SetEntries({
		{
			Key = "0x" .. i,
			Source = v,
			Values = {
				["en-us"] = extra,
			}
		}
	})
end

You need to use string.gsub for this. Your script only matches the exact word, not any part of a string that contained those words.

local LocalizationService = game:GetService("LocalizationService")

local BlockedString = {
    "execute", "executor", "exec", "r6", "r15", "hub", "god",
    "require", "getfenv", "setfenv", "_G", "loadstring", "game", "getService", "workspace"
}

local strs = {}
local extra = "blocked"

-- Helper function to block keywords in a given string. Use str.gsub.
local function blockKeywords(str)
    for _, keyword in ipairs(BlockedString) do
        str = str:gsub(keyword, extra)
    end
    return str
end

local localTable = Instance.new("LocalizationTable")
localTable.Parent = LocalizationService

for i, v in ipairs(BlockedString) do
    local blockedStr = blockKeywords(v)
    localTable:SetEntries({
        {
            Key = "0x" .. i,
            Source = v,
            Values = {
                ["en-us"] = blockedStr, -- Modify dynamically
            }
        }
    })
end
