Zero-Day Pen Testing Under Fire

10/13/2010
A blog post I wrote recently about using zero-day exploits for testing seems to have ruffled some feathers: I got a flood of email about why the concept is immoral, tests like that are not valid, and a host of other problems. Rather than responding to emails individually, this post answers a few common grievances with my testing methodology.

The Case For Zero-Day Penetration Testing

8/26/2010
Penetration testing is a tightrope act where you balance existing knowledge with a mixture of freshly released- and zero-day knowledge. As a penetration tester, I often hear the argument that zero-day attacks do not belong in a test, that there is no time to prepare for them, so of course the target will be compromised. But I have the exact opposite philosophy: zero-day testing should occur to gauge an organization's response to such an attack. If mitigating controls are in place, an unknown att

The more I found out about the election situation, the demonstrations, and the crackdown, the more I felt as if I were reading a political thriller. That's when the ugly side of our hyper-connected society reared its ugly head.

6/2/2009
Like most computer geeks with the latest toys, I can always find a way to play rather than work. My procrastination tendencies can sometimes lead to troubling results (just ask my girlfriend), so I often give vendors some leeway when it comes to patching vulnerabilities. But some vendors just don't get it.

ID Theft and Police Scanners

12/30/2008
When asked why he robbed banks, the flamboyant criminal Willie Sutton answered, "Because that's where the money is." That's the perfect example of how the principle of Occam's razor applies to crime: the simplest solution to a problem is often the best one. With the economic downturn, high unemployment rates, and the booming business of identity fraud, would-be criminals are on the lookout for easy methods to get access to personal information. And we stumbled across one such way during a rece

Hiding In Plain Sight Doesn't Work

12/2/2008
I do a lot of penetration tests and vulnerability assessments for an assortment of business of all sizes. While doing these types of tests, I run into a lot of goofy configurations, strange setups, and wacky ideas that are an attempt by the client to improve security. The most head-scratching setup I constantly run into involves SSH on a port other than the one it is assigned, Port 22.
