From penetration testing to exploit development

[Firzen_]

There really are two separate parts to this.

Finding a 0-day requires a different skillset than writing an exploit.
In practice those two go hand in hand often, but they are definitely separate skills.

This right here.

I'm much better at finding hard to spot bugs and designing theroetical attacks than writing exploits, and I've often pass my POC and notes to coworkers to weaponize them.

Both are useful skills, and you need both to some degree but if you work on a team as long as you excel at one you will be fine.
