Perekrestok.ru

In 2014 the loyalty program of the Russian supermarket chain Perekrestok experienced a significant data exposure. The incident involved approximately 800000 records originating from their customer rewards system. The leaked information primarily consisted of mobile phone numbers along with customer names and patronymics. Additionally the data included bonus card numbers and current point balances. It is important to note that surnames were not part of the original breach but were later appended by third parties using data from other historical leaks to create more complete profiles. The breach highlighted vulnerabilities in retail loyalty databases within the Russian market during that period.
