“Alex” is an Australian citizen with no convictions of cyber treason. Their hobbies include picnics and Following the Law. Metaphorically, they commit crimes, and write very very detailed confession letters. On the side, they organise purplecon, a gentle, pastel, inclusive security conference, but it’s unclear whether the whole thing is like a joke, or what. Their hacking stories, blog posts, and conference talk recordings are all hanging out at https://mango.pdf.zone
In terms of relevant industry certifications and qualifications, in 1633 “Alex” was excommunicated by the Catholic Church for insisting the Earth revolves around the sun.
