Description
On February 5, 2023, Laremo GmbH experienced a ransomware attack that compromised its IT infrastructure. The attack encrypted servers responsible for data storage, rendering the information inaccessible and presumed irretrievable due to the encryption. Initial assessments indicated potential unauthorized access to portions of the customer database and financial accounting systems, though the extent of data exfiltration remained unconfirmed at the time of disclosure. The company acknowledged the possibility that unknown third parties might have acquired sensitive information, including customer master data such as business names, addresses, telephone numbers, contact persons, and email addresses, alongside internal sales records like purchase histories. Operational continuity was disrupted as critical systems became unavailable, though the notification did not specify downtime duration or immediate operational workarounds.
Laremo GmbH responded by engaging law enforcement authorities to investigate the incident and monitor darknet channels for potential leaks of stolen data. The company issued a public Art. 34 GDPR notification on February 22, 2023, to transparently inform customers and business partners about the breach, citing the scale of affected individuals as justification for broad disclosure. No ransom payment details, attacker identification, or initial attack vectors (e.g., phishing, vulnerabilities) were disclosed in the notification. The incident highlighted dependencies on IT systems for core operations across Laremo and its subsidiaries, including LAREMO Gesellschaft für Fahrzeug- und Umwelttechnik, REIFENCENTER Langenwetzdorf GmbH, and SERVICE- UND TECHNIKZENTRUM (STZ) GmbH Triptis. Financial and reputational impacts were implied through the acknowledgment of data loss and potential exposure of business-sensitive information, though specific financial losses or customer attrition metrics were not quantified. Forensic analysis remained ongoing at the time of the notification, with no conclusive determination regarding whether exfiltrated data had been publicly disseminated.
