Ask HN: Coding choices for a security professional

Hi HN,

I work in Cyber security. While my day to day work does not involve programming, I have been writing code since my teens.

I learned C and X86 assembly so I can have a better understanding of how software vulnerabilities and exploits work. I also know python and I am currently a novice with golang.

Since I don't write code for a living,I don't think it would benefit me much to learn a long list of languages.

What programming related specializations,methodologies and topics would benefit someone pursuing a career in Cyber security? My goal more or less is to become good at bug hunting and maybe someday develop useful defensive security software.
