WH Müller

WH Müller was compromised in a ransomware attack attributed to deadlock in June 2026. The organization, operating in the Manufacturing sector in Germany, was added to the group's data leak site as part of an extortion campaign.

deadlock operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.

WH Müller is a family business in the field of electrical engineering and IT technology. https://www.whm.de/
