Wanted by users when WhatsApp has instabilities, the messenger Telegram gained greater notoriety in June due to the leak of conversations that revealed an alleged prohibited collaboration between the current Minister of Justice Srgio Moro, then federal judge, and the attorney general of the Federal Public Ministry in Curitiba Deltan Dallagnol during the Lava Jato operation. Although it did not affect a large number of users, like the other leaks on the list, the situation was widely commented in the country for involving political figures.

In response, Telegram ruled out any possibility of data theft from its servers and said it believed in the possibility of remote hacking of accounts. According to the messaging app, it is also possible that the vulnerability is on the user's phone, possibly infected with malware.
