Presenting rastrea2r at SANS Threat Hunting Summit 2016
Watch my presentation at the SANS Threat Hunting Summit 2016 in New Orleans.

“In this session, SANS instructor Ismael Valenzuela will explain the methods and techniques used by world-class IR teams to leverage the power of open-source tools like Yara and Bro to do IOC hunting when reacting to emergency incidents. State-of-the-art techniques will be presented along with a new open-source tool called rastrea2r, designed to assist with collecting and hunting for IOCs with gusto and style!”
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!
