What Happened
In March 2026, the Turkish restaurant chain Baydöner experienced a data breach that exposed information from over 1.2 million unique email addresses. The stolen data was published on a public hacking forum and included names, phone numbers, cities of residence, and plaintext passwords. A small number of records also contained Turkish national ID numbers and dates of birth, though Baydöner stated that payment and financial data was not affected.
Who Is Affected
Over 1.2 million customers of Baydöner are affected by this breach. The compromised information includes personal contact details for all affected individuals, with a subset also having their Turkish national ID numbers and dates of birth exposed.
Why It Matters
The storage of passwords in plaintext represents a significant security failure, as this practice makes stolen credentials immediately usable by attackers without needing to decrypt them. The public posting of this data on a hacking forum increases the risk that affected individuals will face account takeover attempts, identity theft, or targeted phishing attacks.
What You Should Do
If you have an account with Baydöner, immediately change your password and update passwords on any other accounts where you used the same or similar credentials. Be vigilant for phishing attempts via email or phone, as attackers now have your contact information and may try to impersonate legitimate organizations. Consider monitoring your accounts for suspicious activity, especially if your Turkish national ID number was included in the breach.
