Cyber Security Ctf

In my polytechnic days, I have been exposed to Cyber Security and IoT Security through various events and competitions.

I am familiar with software security concepts, like cryptography, reverse engineering and binary exploitation.

Recently, I have also been learning about Embedded Hardware Security. Do hit me up if you have any learning opportunities in this sector.
