A presentation emailed three years ago containing highly sensitive Polish military information, along with login details to access it, was leaked on Telegram.

The presentation contained details of maps of the military port of Gdynia, the evacuation plan of Warsaw, and other highly sensitive data. OKO.press reported that the password was working several hours after it was leaked. It seems the account holders were unaware that they were breached for three years.

The Telegram account which leaked the presentation, called Poufna Rozmow, is allegedly linked to UNC1151 attackers, which are likely linked to the Belarussian government and Russian special forces. It is alleged that Poufna Rozmowa has been leaking information about Michał Dworczyk, who was then the Chief of the Chancellery of the Prime Minister of Poland, and this leaked email also came from that stolen correspondence.
