  1. Verifying IoCs with Snort and TraceWrangler

    After detecting a network breach it is a good idea to scan the network for further Indicators of Compromise (IoC) to check for further malicious activity. The IoCs are usually derived from forensic investigations into network packets and compromised hosts, and can be quite unique when it comes to more sophisticated attacks (let’s avoid mentioning […]
  2. The Megalodon Challenge

    This year at Sharkfest I offered a special capture file challenge I called “The Megalodon Challenge”. Other than the “normal” challenges you could find at The Reef it was not limited to the size of 100MB, and the solution cannot be reduced to a couple of words or numbers.

  3. Sharkfest 2015 recap

    15 years ago, Wireshark was “born”, so happy birthday! Take a look at the official Wireshark Blog for Gerald’s post. And watch Gerald’s keynote he did at Sharkfest 2013. And, of course, the funny video about how it was all Karen’s idea – which Gerald, at the time it was shown at Sharkfest, had no […]
  7. Sharkfest 2013 Recap

    Yesterday I returned from the annual Wireshark conference, Sharkfest 2013, and once again it has been a great conference. I had four talks (well, actually I had three, but one was scheduled to run twice and it looks like I never do a talk the same way), and one of them I did together with […]
