Data breach
In Turkish: Veri ihlali (veri sızıntısı)
When a company's or service's data is accessed or taken by people who should not have it, often including customer emails and passwords.
You cannot prevent a company's mistake, but you can limit the damage. If your email and password were in a breach, anyone with the list can try them elsewhere, so unique passwords and a second step contain it.
In Türkiye, companies that process personal data have duties under the KVKK, and you can ask a company what it holds about you. For a dispute about how your data was handled, the KVKK Board (Kişisel Verileri Koruma Kurulu) is the body to ask.
What to do
- Check whether your email appears in known leaks.
- Change the password on the affected site and anywhere you reused it.
- Watch for messages that use leaked details to sound convincing.
