whoops i dropped my backdoor down the rabbit hole again

local function decoder(c)
    return string.char(bit.bxor(tonumber(c, 16), math.random(0, 255)))
end
local function undo(data)
    local seed = string.match(data, "^math.randomseed%((%d+)%);")
    local encoded = string.match(data, 'RunString%(%("(%x+)"%):')
    if not (seed and encoded) then
        print(string.format("-- BEGIN DUMP\n%s\n-- END DUMP", data))
        return data
    end
    math.randomseed(seed)
    return undo(string.gsub(encoded, "%x%x", decoder))
end
