Trendyol: Card Fraud within 24 hours of purchase

I made my first and last purchase on Trendyol less than 24 hours ago, and shortly after entering my card details, I was the victim of a textbook payment fraud sequence:

A test charge was made to “Mozilla Foundation”; Followed by a €60 charge labeled “Booking.com” in ILS currency.

The card was never used elsewhere in the last 7 days. I never had any other fraudulent incidents in my life. Trendyol official app was the single point of exposure. I’ve contacted my bank, locked my card, and started the dispute process.

Has anyone else experienced anything like this? Speaking up against these kind of scams / lack of security from mass retailers could help protect millions of consumers.
