Yesterday I started dismantling the virus that is spreading on facebook messenger these days.
What techniques do you use? Any special trick that doesn't require years of practice and could make my job easier? I have already familiarized myself with the nicifier and Function.ToString() traps. Now I have an 850 line JS file full of weird code and I have deciphered like 70 lines so far so I'm looking for some tool, strategy or algorithm to make my job easier.
