How to Really Fix Your DNS

Obviously the first thing everyone should be doing is to apply the patches that the major vendors rolled out, and do it quickly.  It is no longer the time for debate in regard to whether or not you really do need to patch… the answer to that question is quite clear; Yes.  Yes you do. […]

The Internet is a Dirty, Dirty Mistress

It’s been quite a while since I wrote or updated DFW, the I)ruidic FireWall.  Included with that utility is a default iptables firewall policy which the user can use directly, tweak to their liking, or completely throw away and start over from scratch.  NetFilter (iptables) has come a long way since I was actively working […]

Padding the Numbers: Vulnerability Duplication

Recently the OSVDB Blog had an interesting article regarding vulnerability duplication via the “hazard of 0day” wherein a vulnerability being exploited in the wild was mistaken for a new vulnerability when in fact it was not.  This caused many of the vulnerability database vendors to issue new IDs, send out threat warnings, bring in the […]

MS08-033 AVI/MJPG Vulnerability

Since last Tuesday (Microsoft Patch Tuesday), I’ve taken a break from coding Application Protocol Simulators (the hot-button item at BreakingPoint right now) and worked on the Security side of the product. I’ve spent almost exactly one week working on a Strike-set for the ms08-033 AVI/MJPG vulnerability.  The Strike-set includes 8 Strikes all which generate dynamic, […]

CSI-SX 2008

CSI-SX is the new branding for the CSI NetSec conference, which is co-located with Interop Las Vegas, and is essentially the security-focused portion of the overall conference. As with the annual CSI conference, this conference targets a different demographic than I’m used to speaking for as the attendance is usually comprised of very large enterprise […]

ToorCon Seattle 2008

The ToorCon organization puts on some of the best conferences in my opinion, and this last weekend was version 1.0 of their Seattle conference (beta was last year, which I also attended). Friday night was entirely 5-minute lightning talks and then Saturday was entirely 20-minute turbo talks. Sunday was workshops, which unfortunately I could not […]

Context-keyed Payload Encoding Whitepaper

Today, my research paper entitled “Context-keyed Payload Encoding” was published in Uninformed Journal vol. 9. If you’re into cutting-edge exploitation technology, you should check it out. This is the research I presented at ToorCon 9 last October.

Metroid Security Mechanism

Having recently played most of the way through Metroid Prime 3: Corruption, I came across an interesting security mechanism in the game that I haven’t really seen paralleled in the real world…

ms07-061

My second Microsoft Patch Tuesday at the new employer was fairly uneventful. This Tuesday there was only one patch rated critical, MS07-061, and as it turns out it was the bug that I had already worked on last week. Essentially all I had to do was update my strikes from last week with the new […]

CSI 2007

CSI 2007 was the first time I’ve ever attended a CSI conference. I was actually a CSI member way back in the day when I was running my own consulting firm and needed as many business development avenues to explore as possible, but after closing my consultancy and going back to work for The Man(tm) […]
