Tim Blazytko

Hi! I’m a reverse engineering and binary analysis specialist. My work spans independent consulting and hands-on trainings across reverse engineering, program analysis, and software protection. I also contribute to the reversing community through international conference talks, blog articles, research papers, and open-source tools. I hold a PhD and serve as part-time Chief Scientist at Emproof.

For trainings, consulting, invited talks, and general inquiries: tim@blazytko.to.

Trainings

I offer reverse engineering and program analysis trainings, from introductory to advanced courses. Public trainings run several times per year. Private trainings and custom formats are available on request.

Courses

• Reverse Engineering – Binary Program Analysis
• Software Deobfuscation Techniques

Consulting

Need hands-on reverse engineering or binary analysis support? I help with deobfuscation, malware investigations, vulnerability research, and security assessments. I also assist with tooling, automation, and reverse engineering workflows. For inquiries, feel free to reach out via email.
