Why I built Uphack
Marius Horatau
Marius Horatau
Creator of Uphack

Security isn’t a list of payloads to memorise. The useful skill is learning how a system is meant to work, noticing the assumptions it makes, and knowing where to push to break those assumptions.

That’s how I build Uphack. Every lab starts as a believable product with one realistic security flaw buried in an ordinary feature.

I still build every lab myself. Keeping early access small means I can stay close to the people, see where the teaching falls short, and make the next lab better.

Thanks,
