Description

On or around November 1, 2023, INROS LACKNER SE experienced a cyberattack that disrupted its operational infrastructure. The incident caused significant impairments to the company’s communication channels and daily workflows, rendering multiple applications temporarily inaccessible. Primary impacts centered on telephone and file systems, which directly hindered internal and external communications as well as project management processes. The organization publicly acknowledged the attack through a website notification on the same date, confirming the severity of the disruption while refraining from disclosing technical specifics about the attack vector or threat actor. No data breach or data exfiltration claims were referenced in the statement. Restoration efforts commenced immediately, with technical teams prioritizing system recovery to minimize operational downtime.

The cyberattack’s consequences included prolonged inaccessibility of critical business tools, though the company did not quantify the exact duration of outages or the number of affected users. Project delivery timelines faced potential delays due to impaired file systems and communication barriers, though no client-specific impacts were detailed. INROS LACKNER SE established a dedicated contact channel (+49 151 57310204) to maintain stakeholder communications during the disruption, indicating partial mitigation of telephony failures. Internal response efforts focused exclusively on system restoration, with no disclosed containment measures or forensic investigation details.
