THE German rail operator Deutsche Bahn was hit by a large-scale distributed denial-of-service attack that disrupted information and booking systems and lasted for several hours. Regular status updates show the attack began on 17 February and continued into 18 February, hitting its websites and the DB Navigator app while the attack came in waves. At the time of writing, Deutsche Bahn was no longer reporting disruptions, though its sites remained intermittently inaccessible.
It remained unclear who was behind the attack, with the organisation saying it would not comment; however, threat actors previously linked to pro-Russian hacktivism, including Killnet and NoName057(16), have been named as claims in related contexts. The piece notes that DDoS attacks can serve various purposes and mentions that the largest attack observed by Cloudflare in late 2025 peaked at 31.4 Tbps.
