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.
After long development, we have finally managed to produce release version 2 of HeX, codename “Bonobo”. What’s news in HeX 2.0? Check out https://trac.security.org.my/hex/wiki/WhatsNew. Official announcement at http://groups.google.com/group/HeX-liveCD/browse_thread/thread/9a70e96591639ff9
Got several calls from customers today. Their end-customers were calling them telling that their phone is ringing in the middle of the night. When some of them answers, there is no one there. We do some traces on it from our VoIP platform but can not find anything, and concludes there is random SIP INVITES beeing sent directly to the adapter.
This is a common way of searching for open VoIP gateways. They send a SIP INVITE with a real number that they control. If the SIP INVITE is making a successful call to this destination, the traffic suddenly increases after a while.
As effort of the Honeynet Project Malaysian chapter and the RawPacket team initiative, HeX LiveCD was created. It is a Network Security Monitoring (NSM) centric Live CD, built based on the principles of NSM, for analysts, by analysts. This project will be eventually forked to Hex Sensor and Hex Server to complete the cycle of NSM processes. Besides, HeX LiveCD is the blueprint for HornyD. HornyD and HoneySuckle are the toolkits for the Malaysia Distributed Honeynet Project.
Just received account details from the HP. New blog space for me to post some stuff. ;-)
Emulation is an important technology in honeypots and honeynets. It's not always what we want, though, and here's why. As you might know, most bots perform attacks in multiple stages, i.e., they
Catching the exploit and providing a fake shell isn't too hard, as shown in this post. But we certainly don't want a malware to get executed on our honeypot, not even in an emulated environment. Instead, we want to do different things with it, e.g., submit it to a central service for automated analysis.
