We all owe a debt of gratitude to Dan Kaminsky and I’m sad that he’s no longer with us. He’s widely known for saving the internet:
What Mr. Kaminsky discovered in 2008 was a problem with the internet’s basic address system, known as the Domain Name System, or DNS, a dynamic phone book that converts human-friendly web addresses like NYTimes.com and Google.com into their machine-friendly numeric counterparts. He found a way that thieves or spies could covertly manipulate DNS traffic so that a person typing the website for a bank would instead be redirected to an impostor site that could steal the user’s account number and password.
More than that, however, he was a really nice person. The kind of person that you really want to have in the world. Rest in peace, Dan.
