In mid -2011, the Russian instant messaging service QIP (Quiet Internet Pager) suffered from data leakage. As a result of the attack, the data of 26 million unique users were stolen. For a very long time, this base was not published in the public domain and only at the beginning of 2025 a relatively full version of this base appeared, containing 33 million lines and columns with a phone, mail, a nickname, the registration date and the registration site (either Qip.ru or Tvidi.ru). The data dates from June 2011.
