iyzico/2CO Attempts Unauthorized Charge on Garanti Bank Card

On September 6, 2025, I received an alert from Garanti Bank informing me that iyzico/2CO had attempted to charge $6 to my card. I was concerned that someone had attempted this transaction even though my card is disabled for online purchases. The last four digits of my card are 1028.

I had encountered similar transactions before but did not take them seriously. Now that it has happened again, I am concerned that these attempts are continuing and want to request that any security vulnerabilities be addressed. I did not suffer any financial loss because the transaction was declined.

I request that the necessary measures be taken to prevent these types of transactions and strengthen card security.
