2026-07-22 –, Hermitage ABC | General Session
The experts on this panel have been asked to look at a trace file and help find a reason for certain behaviors by attendees at many SharkFests. Based on this, they’ve decided to create a public forum for examining individual trace files with a broader audience for a collective learning experience. Trace files will be gathered from attendees prior to SharkFest and only given to the panel members during the session so that the “not-
knowing what to expect and whether it can be solved” experience of working through an unknown trace file can be preserved.
Come to this session and learn to ask the right questions and look at packets in different ways.
PLEASE SEND PERPLEXING TRACE FILES FOR ANALYSIS BY THE PANEL TO [email protected] PRIOR TO SHARKFEST!
Jasper is the Head of the Computer Security Incident Response Team (CSIRT) at G Data CyberDefense in Bochum, Germany. In that role he is running a team of computer/network/memory forensics experts as well as a couple of malware reverse engineers and a number of Incident Handlers. The CSIRT helps customers that have been compromised (A.K.A. "hacked"), mostly with the attacker's intent of preparing/performing a ransomware extortion.
Jasper's official role at the G Data CSIRT is "Principal Network Security Specialist". He has over 20 years of experience in computer network analysis and network forensics, and has forgotten more about network protocols than most people will ever learn (Token Ring, ATM, some serial stuff). In previous employments he wrote and taught a number of Ethereal & Wireshark 3-5 day classes as well as official VMware classes, and Hacking courses.
Jasper is a Wireshark Certified Analyst (WCA #2) and member of the board of directors of the Wireshark Foundation.
