On April 23, 2025, the price comparison platform guenstiger.de in Hamburg, Germany, was hit by a ransomware attack. The attack led to encrypted data and caused significant technical disruptions. Upon detecting the attack, the company immediately took down its systems and shut down its data center to prevent further spread. The incident resulted in data losses, with visible effects such as missing product data and delayed images on its website.
As of now, guenstiger.de has not confirmed the full scope of the attack but is actively investigating. Company officials mentioned that affected customers were notified directly, and a report was filed with Hamburg’s data protection officer, Thomas Fuchs. The company also informed its business clients via LinkedIn about the situation. Despite the ongoing issues, guenstiger.de has worked to mitigate the attack’s impact and restore normal operations.
While the company hasn’t provided specific details about the encryption or what data was lost, it emphasized that the attack had caused operational limitations.
The affected website had visible disruptions, with missing product tables and slow image loading. The technical team is continuing its efforts to investigate the incident and assess the full extent of the damage caused by the ransomware.
The company’s swift response by disconnecting systems from the internet and shutting down the data center likely helped limit the damage. However, there is still uncertainty regarding the scale of the attack and the full extent of data loss. The Hamburg-based company continues to monitor the situation and work with law enforcement and cybersecurity experts to prevent further incidents.
