STÖK Portfolio
Bug bounty hunter and founder of Blknrth Security AB (Stockholm) who documents hacking methodology (XXE, XSS, SSRF, DNS exploitation, IDOR) through a long-running YouTube channel and recurring live "Bounty Thursdays" sessions rather than written posts alone.
What makes it work
A breakdown of the choices that make this portfolio stand out.
A named security company behind the personal brand
Founding Blknrth Security AB gives the personal content a formal business anchor, distinguishing an established professional operation from a purely hobbyist YouTube channel.
Video as the primary teaching medium
Choosing long-form video over written blog posts for demonstrating vulnerability classes (walking through exploitation live) suits techniques that are easier to show than describe, and reaches an audience that written writeups don't.
A recurring scheduled format ("Bounty Thursdays")
A regular, named weekly segment builds an audience habit and signals ongoing, current engagement with the field rather than a one-time content dump.
What Penetration Testers can take from this
Specific, actionable tips to apply to your own portfolio — no generic advice.
If video suits how you explain technical material better than writing does, use it — the portfolio format should match how you naturally teach.
Anchor a personal brand with a real registered business if you're operating professionally — it adds a layer of legitimacy beyond a personal handle.
A recurring, named content format (a weekly show or series) builds a returning audience more effectively than sporadic one-off posts.
