On 9 July 2021, the Swiss price comparison website Comparis revealed that it had been the victim of a ransomeware cyber attack on Wednesday, 7 July 2021.
According to Comparis, the attack occurred in the morning. Comparis took down several of its sites as a security measure. The attackers demanded money in exchange for decrypting data.
Comparis said that based on the information available most of their databases containing customer information were unaffected. The one exception was data held by Credaris, a partner.
The company said it had started criminal proceedings against an unknown party and was working closely with Credaris and Zurich Police.
Comparis said that it had not paid any ransom money and was in the process of directly contacting customers who were potentially affected.
The company continues to work with external cybersecurity experts to get its systems up and running again. In the meantime, customer contact online and via email will be limited, warned the company.
