I'm an author, journalist, security engineer, and software developer.
I'm the director of information security at The Intercept, an advisor to the transparency collective Distributed Denial of Secrets, and a Tor Project core contributor. I used to work as a staff technologist at Electronic Frontier Foundation, and I helped co-found Freedom of the Press Foundation. I did opsec for journalists while Edward Snowden was leaking NSA docs to them.
I'm the author of Hacks, Leaks, and Revelations: The Art of Analyzing Hacked and Leaked Data, a hands-on book that teaches journalists, researchers, and activists how download, research, analyze, and report on datasets. (No prior experience required.)
At The Intercept, I write about technical topics, leaked datasets, and the far right.
