Description

On March 16, 2024, BerlinerLuft Technik GmbH experienced a professional cyberattack during the night leading into Saturday. The company’s IT department immediately activated internal emergency protocols upon detecting the intrusion, implementing a full isolation and shutdown of all IT systems to prevent further spread of the attack. This decisive containment action disrupted all email communications, halting both inbound and outbound messages across the organization. Production operations for duct components, louver dampers, and sound insulation screens at German and Polish facilities were initially suspended due to the IT infrastructure outage. BerlinerLuft engaged external IT forensic specialists to investigate the breach and initiate system restoration, emphasizing the necessity of thorough remediation to eliminate future recurrence risks. The company explicitly stated no evidence existed at that time regarding potential data theft or compromise but proactively notified relevant criminal and data protection authorities as a precaution.

By March 27, 2024, BerlinerLuft restored production capabilities for the specified ventilation components across all sites, though IT systems remained in emergency operation mode with residual disruptions. Employees regained accessibility via established mobile phone numbers and email addresses, with customers directed to contact designated account representatives for updates. The company warned of probable manufacturing workflow interruptions and delivery delays persisting due to ongoing IT security restrictions, advising business partners to monitor its website for further announcements. BerlinerLuft maintained operational continuity through mobile communications while prioritizing minimal business impact, though security necessities compelled some unavoidable constraints. Internal teams and external experts continued forensic examinations and system recovery efforts without public disclosure of attacker origins, methods, or motives, focusing solely on restoring secured operations and evaluating potential data exposure.
