David Cassel, on The New Stack:

Widely-respected security expert Dan Kaminsky passed away on April 23 from diabetic ketoacidosis at the age of 42. His considerable legacy went beyond expertise with a rare and memorable kindness.

I met Dan very briefly at ShmooCon back in 2004. His kindness was memorable, for sure, but the thing I remember most was just how larger-than-life he was to me at the time. The guy contributed so much to the infosec community and yet remained humble and kind despite it all. It was striking.

By the age of 22, he was giving talks at Black Hat himself, as well as at other tech conferences around the world. Kaminsky told the site he was thrilled to be interacting “with the smartest people I’d ever met in my life.”

Oddly enough, that’s how I felt when I interacted with Dan. It’s a tragedy that he died so young.
