Cyber Incident Victim: Renault
Date:
May 2017
Location:
United Kingdom
Summary
A global ransomware attack disrupted organizations worldwide, including Renault, which temporarily halted production at multiple manufacturing sites. The company swiftly restored operations at most facilities, reporting no adverse effects on customer deliveries despite the cyber incident's widespread impact across various sectors such as healthcare, transportation, and energy infrastructure. The malware encrypted files and demanded payments, affecting critical services and corporate networks but sparing systems running non-Windows operating software.

Description
The WannaCry ransomware cyber-attack emerged globally around May 12, 2017, affecting over 200,000 computers across 150 countries. The malware encrypted files on infected systems, demanding ransom payments to restore access. Critical infrastructure sectors faced widespread disruption, including government agencies, healthcare systems, transportation networks, and corporate operations. Renault became one of the prominent industrial victims when the attack forced the automaker to halt production at multiple manufacturing sites. The company implemented emergency protocols to contain the infection, isolating affected systems from networks to prevent further spread. While production stoppages occurred, Renault reported that 90% of its factories resumed operations relatively quickly, minimizing long-term operational impacts. No direct customer delivery disruptions or data breaches were publicly attributed to the incident at Renault facilities.
Other major organizations faced severe consequences during the same attack wave. In the UK, 48 National Health Service trusts experienced system lockdowns, forcing hospitals to cancel appointments and divert emergency cases. Nissan’s Sunderland plant in England also halted production due to infected equipment. Russia’s interior ministry reported approximately 1,000 compromised computers, though critical servers remained operational using domestically developed Elbrus OS instead of vulnerable Windows systems. China saw extensive disruptions at universities, petroleum payment systems, and hospitals, with institutions resorting to paper records. Global responses included mass system isolations, network shutdowns like those at Spain’s Iberdrola and Gas Natural, and accelerated patching of vulnerable systems—a measure that spared India’s government infrastructure from major damage. Telecommunication firms such as Telefónica contained infections while investigating the scope of compromised assets.
