Description

On February 6, 2023, at approximately 9:30 AM, the owner of a digital manufacturing company in Deggendorf, Bavaria, discovered ransomware installed on one of the firm's computers. The malicious software posed an imminent threat to encrypt all files, with attackers promising decryption upon payment of a bitcoin ransom. No direct communication occurred between the attackers and the company. The incident triggered an immediate response from the Deggendorf Criminal Police Station's Quick-Reaction Team, a specialized unit deployed to cybercrime scenes across Bavaria since July 2021. Upon arrival, investigators focused on securing volatile digital evidence critical for forensic analysis, given the time-sensitive nature of such traces.

The company's proactive cybersecurity measures prevented operational disruption or data loss. Pre-existing backup strategies—specifically designed to isolate secured data from production systems—enabled complete deletion and restoration of affected files without paying the ransom. Forensic examination confirmed no data encryption or exfiltration occurred during the incident. The Quick-Reaction Team simultaneously conducted witness interviews and provided advisory support to the business throughout the containment process. No financial losses were incurred due to the organization's adherence to maintained backups and rapid restoration capabilities. The police emphasized the operational significance of segregated backup systems in mitigating ransomware consequences during their post-incident public guidance.
