Description
On or around November 2, 2023, Russian cybercriminals launched an attack against the KaDeWe Group, impacting its Berlin-based luxury department store KaDeWe, Hamburg's Alsterhaus, and Munich's Kaufhaus Oberpollinger. The intrusion began overnight between Thursday and Friday, targeting the company's corporate networks. Security monitoring systems detected the activity at an early stage, enabling immediate defensive measures that contained the attack's impact before significant damage occurred. As a precautionary step, KaDeWe Group transitioned all IT systems to an offline emergency mode during the weekend following the breach. By Tuesday, November 3, physical store operations had largely resumed normal functionality with only minor residual disruptions, though customers were advised to expect intermittent limitations due to ongoing containment and remediation efforts.

KaDeWe Group CEO Michael Peterseim formally notified customers of the incident via email on November 3, confirming no evidence indicated unauthorized access to customer payment details, account passwords, or personal financial data. The company engaged external forensic specialists to conduct a comprehensive investigation while internal IT teams prioritized restoring full operational stability. Law enforcement authorities, including Berlin's Cyber Crime Unit, were immediately notified, and the organization filed a criminal complaint. Peterseim committed to promptly informing any customers if forensic analysis later revealed compromised personal information, though preliminary findings suggested attackers were blocked before reaching sensitive datasets. Normal business operations resumed with minimal reported interruptions as security teams continued analyzing the attack's scope and reinforcing network defenses.
