Leak-site post text, written by the group
The response stated: "Wizz Air has strong security systems in place, designed to protect the sensitive data of our valued customers and partners." But I would like to know what guarantees you actually offer your customers and others, because this company clearly seems unaware of what’s going on. The breach was published nearly a month ago, and the data has been widely circulated and used. It has also been verified, and it is indeed valid data linked to your employees. Does the company not have any monitoring system? Or perhaps there have been numerous reports of major fraud incidents…
