Cyber attack on OneLog: Publishers in the dark, content temporarily free
Following a cyberattack on OneLog, the Swiss Digital Alliance’s shared login system, the impact remains unclear, as indicated in the second statement. Despite intensive investigations, it has apparently not yet been determined whether data has fallen into the hands of third parties—a sensitive issue, given that OneLog positions itself as a data-protection-compliant alternative to international tech platforms.
The cyberattack on OneLog, the central login system of the Swiss Digital Alliance—an association of the country’s largest media and publishing companies—continues to cause uncertainty. Since Thursday, October 24, 2024, users have been unable to log in to services offered by Ringier and TX Group, while affected content—including paywall articles and e-papers—is temporarily available for free. For NZZ and CH Media, which have not yet introduced OneLog, there are no restrictions. As stated in the second announcement, while analyses of the attack are ongoing, no concrete results have been presented. It therefore remains unclear whether user data fell into the hands of third parties.
OneLog’s operations and processes are designed in accordance with strict data protection guidelines, as the Swiss Digital Alliance emphasizes. Since the attack came to light, OneLog has been in close contact with authorities in Switzerland and the EU and is committed to communicating as transparently as possible. The incident is particularly controversial because OneLog is intended to offer a local, privacy-compliant alternative to the major international tech platforms, whose data-intensive strategies are often criticized by Swiss publishing houses.
Due to the ongoing investigation, no further details can be disclosed at this time. OneLog and the publishers involved emphasize that they are committed to a swift resolution and a thorough investigation. Further information will follow as soon as possible.
