My work focuses primarily on consumer application development, however cybersecurity and CTF challenges like this have always been an interest.

What specific technical skills are required to successfully complete challenges like this?

I suppose so, yes, but probably not to the extent required in some of these challenges.

I just read through https://cybersecurity.att.com/blogs/security-essentials/capt... and some of the accompanying write ups[0] on Github which was very insightful.

For starters, have you participated in a ctf before?

No, I haven't.
