SIXT (car rental) security breach

I'm sure you can guess how the email goes, so I will spare you most of the waffle and corporate-speak, I will just post the first paragraph.

============== Dear customer, we are writing to you today as a very valued customer of SIXT*.

As you have probably read in the press, cyber-attacks on European businesses and authorities are currently on the rise. Our business has also been the target of a criminal cyberattack. Despite comprehensive security measures, these attacks unfortunately cannot always be completely prevented, but at best contained. In this context, we would like to inform you today about a data incident. ============
