Latest presos and blog posts: Malware traffic analysis with “Bro” and Catching “Bayas” on the wire

I don’t have to tell you how quickly life goes by. But I’m just amazed at the fact that it’s been more than 2 years without writing an entry in my blog! Not that I haven’t done anything interesting during this time though. Let me see… I moved to the “other side of the pond” (yup, that’s kind of a change!), I decided to take up my guitar lessons after many years… hey, I even took some cooking lessons for a few months! Hmm.. I wonder if this is a kind of pseudo early midlife crisis :)

Anyhow, on the professional side of things it’s been quite a productive time too. Although I already updated sections of my site to include some of this work, I wanted to share it here:

1. The slides from my talk “Catching Bayas on the Wire: Practical Kung-Fu to Detect Malware Traffic” presented at the 2013 SANS European Forensic Summit, are available on the Papers & Presentation page. A link to the updated version of this talk, presented in a BrightTalk Webinar on March 11th 2014 is there too.

2. My blog post “Identifying Malware Traffic with Bro and the Collective Intelligence Framework (CIF)” is posted on the Foundstone’s Open Security Research site. I’m specially happy and honoured to see that some of this work was more recently included in the latest version of the SANS 503: Intrusion Detection In-Depth class, after I had the privilege to teach the Bro section with Mike Poor and Judy Novak at SANS Orlando 2014. The pcap samples referenced in the post can be downloaded from my Github account.

3. More recently I was invited to participate as Guest Lecturer for the California Polytechnic State University in San Luis Obispo, teaching the Advanced Computer Forensic Methods & Tools class (part of the “Defense Against The Dark Arts” malware research course by McAfee/Intel Security). It was such a rewarding experience to teach to these motivated students!

Finally, I know quite a few people has been asking about Part 2 of the Android Memory Forensics post. Unfortunately something came up that prevented me from completing my work on this topic for more than a year. And by the time I had the opportunity to come back to this, so much had already changed that it didn’t make sense to continue writing the post along those lines. So my apologies for this. I promise I’ll get back to this topic, because it’s definitely a fascinating one.

Best I can probably do for now is to recommend a couple of good resources for you to check:

Talk to you soon!

Security Onion LiveCD is now available

Security Onion ??I read in Doug Burks’ tweet that his Security Onion LiveCD is now available for download. Being a serious Sguil fan, I can’t do anything but recommend you have a look at this new live distro.

You can download it from the following location:

The following information is extracted from Doug’s Security Onion blog:

What is it?

The Security Onion LiveCD is a bootable CD that contains software used for installing, configuring, and testing Intrusion Detection Systems. [Read more…]

Discussion on LinkedIn Group: What is the best IDS system?

LinkedIn Security Leaders GroupThat was the question recently asked by a fellow security professional on the LinkedIn Security Leaders Group.

I’m not usually very excited about posting on LinkedIn Discussion Groups. On top of that, I don’t even have the time to blog anything on my own site. However, I could not resist to write a comment on that discussion about what the best IDS system is. Not when I read the following comment:

Actually the idea of an IDS system has been obsolete for a few years now. Given the latest events in the security area, there are plenty of traffic anomalies far more advanced than relatively-simple signatures out there to deal with.

The best approach nowadays is the IPS (Intrusion Prevention Systems) which would not only detect and inform IT management of the attack events but will also apply the necessary countermeasures to them. Most important of all, this must happen at wire-speed with ASIC-based systems.
