Information security threat researcher, recovering journalist.

This site is the home of various tools, experiments, and things I built primarily for my own amusement. If you find them useful or amusing as well, fantastic! Otherwise, I apologize for wasting your attention budget.

Social media

Current projects:

My day job is cyber threat intelligence. My personal projects are related to my work, but often less serious.
