Who's Behind The Keyboard
A quick rundown of my background and the toolset I bring to every engagement.
My official name is Seif Eldien Ahmad Mohammad, known online as 0xdaphantom. I'm a cybersecurity student at the Faculty of Science, focused on Red Teaming and penetration testing.
I'm building hands-on offensive security skills through internships, self-directed labs, and write-ups — covering everything from password cracking and wireless attacks to full penetration tests against vulnerable machines.
Alongside the technical work, I put real value on communication and teamwork — the parts of security work that turn a good finding into a fixed one.
