Last month we paid $5000 to a guy who found a potential vulnerability in Telegram for Android, and this month we’ve transferred $2500 to HackApp for pointing out weak spots in our iOS code. The most valuable input so far came in December 2013 from a person who found an issue in the MTProto design, so we awarded him $100,000. Whenever a potential vulnerability is found, we are the first to admit it — and fix it.
