What's the truth here? What did Hamed "do"? Exposing a security flaw doesn't get you expelled. He had to have taken it one or more steps too far. I'd like to see the facts.
http://news.ycombinator.com/item?id=5090007 A few days after reporting the flaw, he got caught using http://www.acunetix.com/ (web vulnerability scanner) on their network. He says he was checking to see if they fixed the flaw. I don't think he was intentionally being malicious, but his explanation doesn't jive with his actions. I still think it sucks that they expelled him. But I am unable to logically see how he did…
I think it's perfectly congruent. An entity has your data as well as information on many other people. You come across and report a vunerability. You check that something was done about it. I see no holes in this (aside from the ones in Montreal college's security).
