When I started hacking, a long, long time ago, it was more about figuring everything out myself. I remember very well the first time I hacked something…. I had to step away from my computer. It blows my mind… Wow… what was this thing I had in my hands? Wow, what can you do with it? It feels like a weapon… It is! This made my interest even greater.
No, I didn’t learn “how to do it” from books, I learn by just doing. It means that you never finished/stop learning.
Being a woman who hacks, and having the skills, is/was when I started not so usually. Still, it’s a man’s world. I had to be better than them. Sort of.. I had to prove myself. And not everyone liked it, for sure I can tell you that.. But it’s getting better.
You have to stay ahead of everyone. That’s what makes it also so much fun at the same time. But there is much, much more to it.
You have to learn to program. If you can’t read code, you can’t truly hack. Many so-called “hackers” forget this and remain script kiddies. Making your own tools for hacking is much more fun. Just learn some lines of code.
Linux is the main thing you should focus on. With Linux, you have the power, you own. Once you master Linux, you’ll understand why hackers live in the terminal.
My tools are used by hundreds of thousands of hackers worldwide. Projects like shodan-eye, google_dork_list, and ghost_eye are actively used by the security community.
My mission? Make complex things simple. I want people to think for themselves. My goal is to create a better world.
This is my passion… There’s nothing so great! Be curious, be smarter than the rest. Hacking is not a hobby, but it’s a way of life.
Jolanda de Koff | Bulls Eye
Hello, I am Jolanda de Koff, probably better known as Bulls Eye. Hacker, penetration tester, researcher, programmer, self learner, and forever n00b. Not necessarily in that order. I like to make my own hacking tools and I sometimes share them with you.
Things I love: computers, hacking, Linux, music, dogs, cats, friends, physics, gardening, being outdoors, coffee, traveling, and so much more.
I live with my dog Sep somewhere in the Netherlands.

In memory of Babbe, my wolfdog.

About HackingPassion.com
Becoming a hacker is simple but not easy. There are so many resources online, but a lot of them are wrong and outdated. It is hard to stay up to date, even with a background in security.
My goal is to teach people and raise awareness by showing the methods real black hat hackers use. If you want to stay up to date with the latest in the hacking world, you have it all right here.
Some projects
BullsEye0.com
Some time ago I started HackingPassion.com. Great fun, but I missed something. There is a lot I want to write and make videos about that is not hacking related. That is why there is BullsEye0.com.
Basically everything a bit Linux, open source, how-to, making a website, installing a server, installing and using different programs, you name it. And maybe a little bit about me.
Tools I made
All of them are on my GitHub, and each one has its own write-up here on the site.
- Shodan Eye collects everything about devices connected to the internet using the keywords you enter.
- Blue Eye is a recon toolkit. Ports, headers, subdomains, IPs and company emails in one run.
- Ghost Eye does information gathering, footprinting and recon. Point it at a domain or IP and go.
- Dorks Eye is Google hacking dork scraping and searching. Find dorks and spot vulnerable pages fast.
- Google Dorks List is a collection of 13,760 Google Dorks to find sites that leak what they never should.
F.A.Q.
A: It does not hurt to ask. Bulls Eye is picky about which companies can sponsor the work here. You will never find credit card, shoe store or pharmaceutical companies sponsoring.
If you feel your company or organization would make sense to partner with HackingPassion.com, drop me an email and strike up a conversation.
