About Calvin Lai (fkclai)

I am working in the IT industry for over 22 years. For the first 10-years worked on web applications and middle-tier development, in recent years, I focus on application security and management work.

This blog is a publicly accessible personal note to keep all of my security on HTB & VulnHub, CVE Exploit PoC, Exploitation Guide & cheatsheets, penetration testing experience and study materials related to Information Security.
Most of the techniques recorded here are coming from the Internet by other security researchers. I just reference it and try to consolidate, rethink and reuse it. This is my way of learning, doing, reading, following and reviewing. Finally, take notes for future study.  
Do not expect the note completed without error. 
Do check the Internet and try it yourself.
Do remember there are many ways to do the same things.
Be creative in your work.
