Citycomp GmbH

Citycomp GmbH is a Germany‑based company that provides IT infrastructure services to major global corporations. It has served customers across several sectors, including automotive, technology, telecommunications and retail. This client base indicates that its infrastructure solutions are used by organisations with demanding performance and security requirements. The company’s role is to supply the underlying technology platforms that support the operations of large multinational enterprises. Being headquartered in Germany places it within a key European market for enterprise technology solutions.

In April 2019 Citycomp GmbH suffered a cyberattack in which attackers accessed its systems for over a month and exfiltrated more than 500 GB of sensitive financial and private client data. The intruders cited inadequate security as their motivation and demanded a $5,000 ransom while threatening to release the stolen information through a dedicated website. The company refused to pay the ransom, initiated a forensic analysis, notified all affected organisations and cooperated with law‑enforcement authorities. Multiple high‑profile clients confirmed awareness of the breach and launched independent investigations alongside the provider. The attackers claimed sole responsibility for the compromise and stated they would not target the client organisations directly.
