Kazakhstan ATF Bank

In late 2020 a significant data exposure involving ATF Bank in Kazakhstan was identified. The incident involved an unsecured database containing sensitive information of customers and employees. ATF Bank was later acquired by Jusan Bank which makes this historical data particularly sensitive for current account holders. The breach included personal identifiers and financial details that could be exploited for targeted phishing and financial fraud. Security researchers discovered the data on public forums where it was offered for sale or shared among cybercriminals. The exposure highlights risks associated with legacy banking systems during institutional transitions.
