On September 3, 2025, users of Nays, the financial application owned by İşbank, received an unusual notification. The notification displayed the message “NO SYSTEM IS SAFE!” along with an image showing masked individuals.
Around the same time, similar notifications were reported by users of the Fenerbahçe SK mobile application, according to screenshots shared on social media.
This has led to speculation that the applications may have been subject to a cyber incident. However, as of now, no official statement has been released by the institutions involved.
Cybersecurity experts highlight that such incidents may either stem from vulnerabilities or be part of broader testing scenarios, but accurate information can only be confirmed through official announcements.
For users, the following steps are recommended in situations like this:
Do not panic.
Wait for official statements.
Regularly check for application updates.
Use strong passwords and enable two-factor authentication for extra protection.
