title: How to check what an obfuscated program does?
body: <p>It's most likely a virus: I got it from a local chicken shop website, asking me to update Firefox as it was apparently out of date. Which it wasn't, but okay. I clicked the thing because why not, and it downloaded a .JS file.</p>
  
  <p>The file itself is seemingly a pile of gibberish, here's the first line:</p>
  
  <p><code>(function(wyfdysu){var iwtquom="arwob"["c"+("H","q","n","o")+["U","n","H","H"][(-</code></p>
  
  <p>So yeah, aside from a VM, is there any way I can safely inspect this?</p>
