SANS Penetration Testing:

Finding Zero-Day XSS Vulns via Doc Metadata

[Editor's Note: Chris Andre Dale has a nice article for us about cross-site-scripting attacks, and he's found a ton of them in various high-profile platforms on the Internet, especially in sites that display or process images. He even found one in WordPress and responsibly disclosed it, resulting in a fix for the platform released just a few weeks ago. In this article, Chris shares his approach and discoveries, with useful lessons for all pen testers. Oh... and if you are going to test systems, make sure you have appropriate permission and don't do anything that could break a target system or harm its users. Thanks for the article, Chris! --Ed.]

[Editor's Note: With last week's release of iOS 8, we enter a new era of security fixes and issues for Apple's flagship mobile operating system. But, even this latest version faces an issue that comes up regularly with iOS and other mobile operating systems: Lock Screen Bypass. In fact, there are dozens of different ways to bypass the Lock Screen on a device, each applicable to different versions and subversions of iOS. Thankfully, Raul Siles has inventoried a whole bunch of them in this article, providing a useful reference for penetration testers who need to show the risks associated with a given iOS feature or version number. Raul also offers tips for hardening iPhones and iPads against these kinds of attacks. Nifty stuff! --Ed.]

In this presentation, John and Ed will cover some key components that many penetration tests lack, including why it is important to get caught, why it is important to learn from real attackers, and how to gain access to organizations without sending a single exploit.

Dealing with the Many Stages of Pen Test Result Grief - Part 2

By Ed Skoudis

In this series of articles, we're looking at some of the grief that penetration testers often encounter when they deliver their results and recommendations. Our premise? You, a great pen tester, work your tail off to conduct a wonderful, high-value, technically awesome pen test. The result? Target system personnel vomit all over your findings, push back on your recommendation, and just plain don't see the value of what you've done. The series, which began with article one here, focuses on practical tips you can use to avoid such situations up front, or, if they do occur later on, methods for defusing the situation and demonstrating the real value you are providing.
