h4d35x0 is a persona: a handle, a set of repositories, and a field log. It is not a company and it is not an information-security business.
There is one shirt. It is made to order by a print-on-demand shop when someone buys one. That is the entire commercial surface.
The code lives at github.com/h4d35x0. The log is what was pointed at hardware, and what was deliberately not done to it.
