On September 7, 2023, it was revealed that customer data from "MTS Bank" had been compromised. A hacking group claimed to possess 21 million records, although they only became publicly available towards the end of the year. The leaked data includes names, phone numbers, email addresses, dates of birth, Tax Identification Numbers (INN), and partial bank card details. Additionally, SHA1 hashes of the card numbers were exposed, which, through brute-force methods, could potentially reveal complete card numbers. Some individuals were associated with multiple phone numbers, hence the total number of phone records exceeded 70 million.
