So it feels like everybody is pretty wrapped up in the political aspect of this and are probably not necessarily that interested in the technical part of it, but this has some interesting parallels to a recent story in the tech world where a security researcher was searching for vulnerabilities in Facebook's infrastructure, and ended up pushing a little too hard apparently. Dude's side of the story is
here, and there was some good
discussion of it on the Hacker News forum (note: not that kind of hacker, long story).
It's a very fine line to walk, trying to demonstrate to a third party that they have security vulnerabilities in a live application. If you have too light a touch, it's very easy for them to just shrug and say "we're looking into it," but if you're too heavy-handed, you can wind up in jail, no matter how noble your intentions were. That said, Uretsky definitely fucked up here and I imagine he's feeling pretty awful tonight knowing what he brought down on the Sanders campaign.
