Dodo Pizza, a Russian pizza chain with about 1,500 locations, has confirmed that it suffered a cyberattack. The confirmation follows public claims by hackers that they had breached the company.

According to Dodo Pizza, the potentially compromised information includes customers' names, addresses, email addresses, phone numbers, dates of birth, and order details. That is a broad set of personal and transactional data that could be used for identity theft or targeted phishing.

The company did not disclose how the attack was carried out or how many customers were affected. The incident highlights the risk facing large restaurant chains that hold detailed customer records.
