Data breach feared after cyberattack on AMEOS hospitals in Germany

Posted on July 22, 2025 by Dissent

DPA reports:

A cyberattack on Swiss hospital group AMEOS may have exposed sensitive patient and staff data, the company said on Monday.

The attack, which took place two weeks ago, caused significant disruption across the group’s German operations. The company described the episode as a targeted assault on its IT infrastructure.

In a statement, AMEOS said that it cannot rule out the possibility that personal data – including contact details – could be misused or shared online.

AMEOS says it operates more than 100 facilities at over 50 locations and treats over 500,000 patients annually, making it one of the largest private hospital groups across Switzerland, Germany and Austria.

A notice on AMEOS’ website today reads:

Due to an attack on our IT infrastructure, not all digital services are currently available. We are working diligently to resolve the issue. We are still available to assist you by phone. 

Notice of data protection incident pursuant to Art. 34 GDPR

The notification does not specifically address whether this attack involved encryption of any files and whether AMEOS received an extortion demand.
