👨💻 About Me
Hi there! 👋
My name is Daniel Ayodeji, also known as Deesick. I focus on security research, phishing investigations, threat intelligence, and adversary TTP analysis. My work explores how attackers operate, the techniques they use, and how their infrastructure, tools, and tactics can be investigated and detected.
This website is my digital notebook and research resource, documenting phishing campaigns, malicious infrastructure, attack techniques, and hands-on security investigations. I also share practical notes on vulnerability research, Active Directory attack paths, and lessons from Hack The Box labs. The goal is to turn technical findings into useful knowledge that helps security practitioners better understand threats, recognise attacker behaviour, and improve detection and defence.
Whether you’re learning security research or already working in the field, I hope you find something useful here.
