While it seems to be impossible to say whether waledac is the successor of storm or not, what we can do is take a look at the traffic encryption. They guys over at Shadowserver have already blogged some details about this. We at the Giraffe Chapter investigated waledac's communication protocol further. Here are our results.
The new release 0.5 of Picviz is out. This version comes with real-time mode enabled (and adds the libevent dependency) among other things, such as new properties and variables.
Get it from the usual place.
What is Picviz?
When considering log files for security, usual applications available today
either look for patterns using signature databases or use a behavioral
approach. In both cases, information can be missed. The problem becomes
bigger with systems receiving a massive amount of logs.
Wishing you all the best for the new year, and all the best for the honeynet project,
Waledac is wishing merry christmas
There is a new bot in town. It's called Waledac. The way it is spreading reminds a lot of people of the good old storm botnet: An email is sent containing a "christmas card" in form of the executable "postcard.exe".
A preliminary view on the binary has been given by the Shadowserver guys (Steve Adair).
I had the chance to have a first look at the binary (MD5 ccddda141a19d693ad9cb206f2ae0de9) and want to note down some of my few findings to let the hunt begin.
Once a year the Honeynet Project brings together members from around the world for a one week workshop on honeyopt research, development and deployments. We are excited that for this year's event the workshop will be sponsored and hosted by the International Multilateral Partnership Against Cyber-Threats (IMPACT), a public-private alliance against cyber threats. IMPACT is based in Cyberjaya, Malaysia. We are very excited for this opportunity as it will be the first time we have hosted the event in Asia. We would like to thank IMPACT for t
As libemu had it's second release (0.2.0) lately, I'll try to introduce it to the audience who did not hear about it yet.
libemu is a small library written in c offering basic x86 emulation and shellcode detection using GetPC heuristics. Intended use is within network intrusion/prevention detections and honeypots.
This post is split into four parts:
I gave a lecture on Picviz during the Usenix Workshop on the Analysis of System Logs (WASL 2008).
My slides 'Picviz: finding a needle in a haystack' are available right here.
I also ran for the Cray log analysis contest analysis. Slides of stuff I discovered are here.
Welcome to our new website as we enter the age of Web 2.0. We have created a more dynamic website to allow our membes to create and publish their own content. We have so many different activities going on with our various members that it can be challenging even for us to keep up. The goal is that each member can now publish and share with the community whenever they like. In addition we still have all the old content on the website. We are still in the process of moving some content over, such as some of our KYE papers. If you find content missing, a broken link or have any sugg

If you followed IT security related blogs or mailinglists lately, you are aware that a critical server service vulnerability in Microsoft operating systems was published recently. I'm not going to talk about the details here, there are great resources available elsewhere (and the "reversing the ms08-067 patch" article isn't the only advice about exploiting holes you get on that page).
OK, what have we got this time? One of our honeytrap sensors caught an MS08-067 exploitation attempt today which we take as an example to show how to perform a quick analysis and check what it does. If you want to play along, get the (sanitized) pcap from here.
I've been looking on ipv6 lately, and even though I got a global /64 for free from he.net, I'm not that amused about ipv6 yet.
