Markus Satzger is CTO of Welt der Wunder Sendebetrieb GmbH and Welt der Wunder e-lab. He began his career by training to become an IT systems administrator at Deutsche Telekom.
Markus has earned the AWS Cloud Quest: Cloud Practitioner and the AWS Cloud Quest: Solutions Architects certifications. In 2024, he completed further training as an IT forensic investigator.
My background in business informatics exposed me to the challenges of cybersecurity, which sparked my interest in understanding how digital crimes are investigated and how evidence is preserved to support legal cases.
The most challenging aspect is dealing with encrypted or obfuscated data. It requires specialized skills and tools to uncover hidden information while maintaining the integrity of the evidence.
Digital evidence preservation involves creating a forensic image of the data, ensuring it’s an exact, bit-for-bit copy. The original is kept untouched, and chain of custody protocols are followed to document every step.
Social engineering, particularly phishing attacks, is highly dangerous because it targets the human element, which is often the weakest link in security.
I stay current by attending conferences, participating in professional communities, and continually pursuing certifications. I also regularly monitor threat intelligence reports and cybersecurity news.
