<p>We would like to use this opportunity to thank the users ABC, <ahref="https://twitter.com/defusesec">@DefuseSec</a>, <ahref="https://twitter.com/hackappcom">@hackappcom</a>, <ahref="https://twitter.com/morj">@Morj</a> and <ahref="https://telegram.org/blog/crowdsourcing-a-more-secure-future">x7mz</a> who helped us further improve security of the client apps and expand <ahref="https://core.telegram.org/mtproto/security_guidelines">guidelines</a> for third-party developers.</p>
<p>Since we have no winner in the current challenge, we are going to launch a new competition, with an easier task, but a larger prize. The new competition will allow participants not only to intercept traffic, but to manipulate it as well. We are now building the tools that will enable the contestants to perform all kinds of active attacks. Once the platform is ready later this month, we will announce the new contest on Twitter. Please follow us at <ahref="https://twitter.com/telegram">@telegram</a>!</p>
