How to Deobfuscation Lua Script?

Question

local script= string.dump(
    function()
        print('Hi')
    end
)

buff=""

for v=1,string.len(script) do
    buff=buff..'\\'..string.byte(script,v)
end

print(buff)  

script turns into byte code, any idea how to reverse it?

Answer 1

You cannot reverse bytecode to Lua source but you can list the VM instructions with luac -l.
