In June 2023 an incident involving the Ukrainian internet service provider Bigline based in Kharkiv became public. The breach resulted in the exposure of approximately 380000 user records. Hackers managed to gain unauthorized access to the systems and subsequently published the database on various underground forums. The leaked information includes sensitive details such as electronic mail addresses, full names, physical addresses, and most critically passwords stored in clear text format which poses a significant security risk to the affected subscribers.
