Description

On or around April 4, 2021, Würth France experienced a widespread network outage attributed to an unspecified "incident de sécurité informatique." The disruption impacted core IT systems, including the subsidiary Würth Modyf France, rendering the group's data center non-responsive and forcing the temporary shutdown of its e-commerce platform under the guise of maintenance. Customer service communications acknowledged a "problème technique important" requiring full mobilization of internal IT staff. Group management, including Directoire President Claude Kopff, confirmed external cybersecurity experts were engaged in remediation efforts. By April 12, logistical operations had partially resumed, enabling physical stores to process customer orders manually, though external IT services remained unavailable. The incident caused significant operational constraints, particularly in order processing and billing systems, with delays expected until full IT restoration.

The disruption severely affected Würth's business operations, necessitating manual order processing at Würth Proxishop outlets and causing billing delays. Downloads and communications systems were impaired, directly impacting supply chain logistics. While the company avoided explicit confirmation, contextual details—including the systemic network failure, engagement of specialized security responders, and operational parallels to contemporaneous ransomware events—strongly suggested a ransomware attack. This incident occurred amid heightened cyberattack activity across France during April 2021, including breaches targeting municipal services and healthcare facilities. Globally, ransomware incidents decreased from over 200 in March 2021 to approximately 70 during Würth's incident period, though regional attack density remained elevated.
