DetectiveZhang

Follow the evidence. Understand the system.

I'm Nurzhan, a junior cybersecurity specialist focused on penetration testing and SOC analysis. On DetectiveZhang, I explore CTF challenges, OSINT, digital forensics and the reasoning behind a security investigation.

Expect practical walkthroughs, lab notes and curious cases: from finding a clue to explaining what it means. I also enjoy ARGs and internet mysteries.
