Ask HN: Searching for Computer Security Mentor

I am looking for a computer security mentor. In particular, I am looking for someone who can:

1. Software security: buffer overflow - implementing a stack overflow attack and a return-to-libc buffer overflow attack. Familiarity with GDB.

2. Use Cuckoo to analyze malware

3. Cryptography

4. Web Security

I am deeply interested in these things and would love to learn from someone who is an expert in this domain.
