In this contest you assume the role of a malicious entity in full control of both the communication lines and the Telegram servers themselves. Today we announce a new contest with an easier task and a larger prize - $300,000 for cracking Telegram's encryption, and this time contestants can not only monitor traffic, but also act as the Telegram server and use active attacks, which vastly increases their capabilities. Security researchers are welcome to submit any issues they find in the Telegram apps or protocol to us at All submissions which result in a change of code or configuration are eligible for bounties, ranging from $100 to $100,000 or more, depending on the severity of the issue.Įarlier this year we had a contest to decipher intercepted Telegram messages, that did not produce a winner.
This contest is over, but the Telegram Bug Bounty Program is always open.
