Introduction to ClamAV's Low Level Virtual Machine (LLVM)
Users of prior versions of ClamAV may have noticed a drastic increase in the size of the tarball with the introduction of 0.96. This is due to the addition of a bytecode interpreter, and a JIT Low Level Virtual Machine (LLVM). It greatly extends ClamAV detection capabilities by being able to interpret/execute bytecode. Not a lot of documentation exists as yet about how to write bytecode for

Malware on Android? Big deal!
Malware and Google's Android OS are two of my favorite things to play with. You would think that when I heard that there was a Trojan in the wild targeting Android devices, I'd be all over it. Indeed, I was. But I was not happy because I just don't like the sound of "malware" and "Android" in the same sentence. I got a copy of the Trojan (MD5: fdb84ff8125b3790011b83cc85adce16) and proceeded to
Snort 2.9 Essentials: The DAQ
The recently released Snort 2.9 Beta introduces the Data AcQuisition library (DAQ), for packet I/O. The DAQ replaces direct calls into packet capture libraries like PCAP with an abstraction layer that make it easy to add additional software or hardware packet capture implementations. DAQ 0.1 supports PCAP, AFPACKET, NFQ, IPQ, IPFW, and DUMP which is used for testing.
So why the change? The DAQ
Quick analysis of a webpage leveraging CVE-2010-1885 (aka the help and support center vulnerability)
In a previous blog post I was writing about an increase in attacks against an at the time, un-patched vulnerability. Microsoft patched it on July 13, which doesn't mean that people aren't still trying to own un-patched machines.goodgirlsbadguys.com (213.155.12.144) is a domain registered on July 19 2010 with a registrant address listed in Cambodia.

Sourcefire VRT DI is Hiring
Here's your chance to become part of the Intelligence unit that powers the Vulnerability Research Team. We know all, we see all and we say almost nothing to anyone about anything. Kinda. Alright, not really. We get the data, we manage the data, we mine the data, we give out information and actionable intelligence. In short, we separate the intel from the noise.

Innovation -- You Keep Using That Word...
So, this week, the OISF has been on a media blitz about Suricata, their open-source Intrusion Detection System. As always, my preference is for you to review the information yourself, so before I give you my thoughts about the state of Suricata, here are some links:

The Power of Scapy
There is a special place in my heart for someone who accidentally causes all the Macs in the office to repeatably crash at the Grey Screen of Death. If you too like fun "accidents" or need to craft up some packets check out Judy Novak's SANS class on Scapy. This is an in-depth start to finish class on the Scapy API, and will take you from just knowing about Scapy to building complex packet
New Rule Categories
Three new rule categories were introduced yesterday (Tuesday, 13th July 2010) in SEU 348 and into the VRT Certified Rule packages. I'd like to take a moment to explain what's in these categories, where the data behind them is coming from, and what you should do if you turn them on and they start firing.
The initial set of rules for these categories was pulled from the specific-threats and
