Hacker attack on S-Bahn Hannover: website paralyzed for two hours!

On July 24, 2025, the S-Bahn Hanover website was the victim of a hacker attack that paralyzed the website for two hours. According to NDR was the result of an overload attack (DDOS attack). Websites are called excessively in a short time, which leads to their overload. The IT department of the S-Bahn was able to fix the problem quickly, so that the page can now be reached for most users.

The attackers have so far been unknown and the incident is classified in a larger context, because similar attacks have recently been heaped. On July 9, 2025, a politically motivated attack was found, in which pro-Iranian messages were reported on screens in bakeries in several counties. These recent incidents illustrate a worrying threat situation in the field of cybercrime, as well as the Federal Office of Information Technology (BSI) emphasized.

Enlightenment and international exchange

International cooperation was crucial to effectively combat cybercrime. In Lower Saxony, too, people feel the consequences of these attacks, and it is clear that the danger will continue to be high in the future.
