About.

Hi, I’m Yuval.

I like taking software apart to see what makes it tick. Occasionally, I find something its developers didn’t intend.

Rootinator is where those rabbit holes turn into security research, vulnerability disclosures, and technical notes. Sometimes the result is a finding. Sometimes it’s a useful tool. Either way, I try to leave with a better explanation than “that’s weird.”

What you’ll find here

Public disclosures and CVE publications, a closer look at the bugs behind them, and projects that make the research process a little less tedious. I write about the reasoning as well as the result: what caught my attention, what I checked, and what the evidence actually supports.
