Basel, 12 April 2022. On 11 April, Baloise detected a cyberattack on parts of its IT infrastructure, primarily systems of Basler Germany. According to the latest information, no company data or customer data has been stolen and no systems have been encrypted. The affected systems have been identified and isolated.

The defensive measures put in place mean that customers and employees in Germany are currently experiencing some restrictions on the use of our services and IT infrastructure

An attack on parts of Baloise's IT infrastructure was detected on 11 April. Baloise reacted swiftly by taking countermeasures to fend off the attack. The compromised systems have been identified and isolated, but this is currently resulting in temporary restrictions that are affecting parts of the sales organisation of tied agents of Basler Germany. The defensive measures may lead to further temporary restrictions on Baloise's services. At present, Baloise does not believe that any other systems will have to be isolated. According to the latest information, no company data or customer data has been stolen. We will continue to do everything we can to protect Baloise and the data of its customers and partners from such attacks.

We apologise to all affected customers and partners for any inconvenience caused. If new information comes to light, we will provide an update on the incident.
