ReadI just realized that my Friday post said Thursday as the day of the week. Oops….QA is fired!

Here’s the list:

Detecting BBB/IRS/FTC/Proforma Trojan-Infected Users on Your Network – Here is a good example of where system and device logs are important.

If you keep logs of firewall/proxy or DNS server traffic, you may be able to spot infected users by traffic analysis. This activity has been going on since at least February, so it is prudent to go back in the logfiles at least until the beginning of 2007 when searching.

Heap Spraying vs. Heap Feng Shui – Good explanation of some proof of concept code.

The heap allocation code used in this exploit was quite advanced and completely different from the conventional Heap Spraying code used in the attacks that I’ve seen so many times. In this case, the exploit page (keyframe.html) used a special compact heap manipulation library named “heapLib.js” which after some investigations introduced me to the mystical world of the “Heap Feng Shui”.

How to create a computer-emergency response team – Although not a single source of information this article does get you started with important information on how to form a CERT.

Perhaps the most important thing needed for a successful recovery from a data breach is a prebuilt team of employees, pulled from different departments, who can lead the company out of crisis.

New Skillz Challenge! – For those of you with some free cycles.

Hello, Challenge fans! The Intelguardians crew is back this month with another challenge to tickle your fancy and bake your noodle. This month, Matthew Carpenter takes the helm, penning a challenge based on the movie Serenity. Shockingly, a recent SFX magazine poll found that Serenity had overcome Star Wars as the most popular Sci-Fi movie among its readers. It’s amazing what someone can accomplish with a bot-net voting in these on-line polls… Isn’t it, Matt? I hope you enjoy the challenge, as you help the Serenity crew thwart a nasty bot-net to escape the Reavers and the Alliance.
