Deobfuscating Javascript [closed]

by

This a really obfuscated version of:

document.writeln("<a href=\"mailto:[email protected]\" title=\"Contact\">Contact</a>");

I assume it is obfuscated this much to avoid spammers. But of course spambots could just render the page with Webkit and traverse the DOM for email addresses … 😉

So.. how to deobfuscate?

  1. Go to http://jsbeautifier.org/
  2. Paste the source and beautify it
  3. Edit the function f(x) so it does console.log(o) instead of return o
  4. Execute the modified code and beautify its output.
  5. Repeat steps 2-4 until it is readable.
