About me
About Me
I am Daniel, an offensive security and penetration testing focused student software engineer at 42 Vienna, with practical experience in system interaction, network service implementation and runtime execution behaviour through project-based training.
My work is grounded in systems-level thinking and developed through hands-on exploration of and experience with process lifecycle manipulation and detection analysis, system exploitation and session control mechanisms, endpoint behaviour analysis and detection bypassing in controlled environments.
I focus on understanding how systems execute, isolate and expose behaviour at runtime, particularly through process control, input simulation and low-level interaction mechanisms.

Current Focus
- Preparing for Certified Red Team Professional (CRTP) certification
- Penetration testing fundamentals through system-level experimentation
- Developing offensive security labs in controlled environments
Core Areas
- System exploitation and session control mechanisms: setsid, process groups, signal handling
- Ephemeral execution: runtime isolation and persistence boundary in volatile memory environments
- X11 internals: window manager bypass, input grabbing, session takeover
- USB HID simulation (embedded system): user input emulation, endpoint testing and detection evasion
