Without any intro - crap that I usually write explaining why I had to write this post, I’m going for the subject. You(general junta or web developers or scared security guys) might see some eval packed javascript which phishing idiots ask you to copy paste on your URL bar and hit enter key. Unpacking JS is a PITA was an answer that my brain use to give whenever I think about it. Just now, I found a very easy method to convert it into readable Javascript without any extra tool (IE boys, run away) Its very simple in FF or Opera. FF guys, all you need to do is …

  1. Copy the eval packed JS. something like —— eval(function(p,a,c,k,e,d){e=function(c) …………………. }
  2. Open Error Console on your firefox
  3. Paste the packed JS in Code input tab
  4. Add eval = alert; at the beginning of the code
  5. Hit Evaluate
You will get the proper javascript for the packed javascript. Copy paste it into any code prettifier. It will become perfectly readable. Opera folks, follow this. Packed JS is a huge asset for Phishing as who would have expected that packed JS in this code will make you join around 26 communities and send some stupid message to all your friends without your knowledge as soon as you copy paste some JS code on your URL bar and hit enter. Edit: Or the simplest of all, as Rob Reid suggested, just head to the unpacker at Strictly Software. Thanks Rob.
