I’m Billy, an 18 year old developer from the UK interested in mobile security, iOS, ARM and software exploitation. On this site you will see various written tutorials related to exploit development and hacking aimed at beginners as well as a bit about me.

I also run a YouTube channel teaching similar things which you can find here.


The first set of tutorials on this site are based around the basic concepts of binary exploitation specifically on the ARM platform. This will apply to most mobile devices but it’s best if you use an iOS device to follow along as that’s what I’ll be using.
