Background
Online and shipping things since the late '90s. Wrote for TechCrunch from 2007 covering startups, security, and emerging tech, and helped source early investments at CrunchFund — including DigitalOcean, GitLab, Pachyderm, ReadMe, and Streamable.
Before that, security research. Most-cited work: the 2011 Facebook logged-out tracking exposé (covered by the NYT and BBC), the 2014 MyGov vulnerabilities disclosure, the iCloud and 2014 celebrity photo hack analysis, and a piece on using information leakage to trade stocks. Web app security advisories under various aliases since '96.
Also along the way: BeatCovid (GitHub), an open-source COVID symptom-survey platform run with the University of Swinburne, and Infotorch, a data journalism project.
University of Wollongong drop-out. Blogging since November '99.
