More than a year's worth of internal chat logs from a ransomware gang known as Black Basta have been published online in a leak that provides unprecedented visibility into their tactics and internal conflicts among its members. The Russian-language chats on the Matrix messaging platform between September 18, 2023, and September 28, 2024, were initially leaked on February 11, 2025, by an individual who goes by the handle ExploitWhispers , who claimed that they released the data because the group was targeting Russian banks. The identity of the leaker remains a mystery. Black Basta first came under the spotlight in April 2022, using the now-largely-defunct QakBot (aka QBot) as a delivery vehicle.
