United Airlines awards hackers millions of miles for revealing risks
Taking a quick look at http://www.united.com/web/en-US/apps/mileageplus/awards/trav... it seems 1 million miles ~= $3000-$12000 depending on destination, date, etc. It doesn't seem all that bad of deal, except plenty of people don't fly often enough to even make use of this, and you have to fly united, which for me would kill all the value.
