Cyberattackers hacked Coolworld, an EFS contractor, and reprogrammed blood-sample cold rooms in Bourgogne-Franche-Comté from –30 °C toward 110 °C; EFS and the Health Ministry say no operative consequences, though frozen plasma for transfusion was among the targeted stock.
French satirical investigative weekly Le Canard enchaîné reports that Coolworld, a service provider for the Etablissement français du sang (EFS – French Blood Establishment), suffered a cyberattack during the night of 1–2 November. Coolworld maintains cold-storage containers used by EFS, including in the Bourgogne-Franche-Comté region. Attackers remotely reprogrammed cold rooms that normally store donor samples at –30 °C, setting them to reach 110 °C. The article describes this as an unprecedented malicious act targeting sanitary refrigerators after previous incidents involving supermarket fridges. The French Ministry of Health stated that there were "zero operative consequences" because the situation was detected in time. EFS said that an on-call technician noticed the temperature increase in the cold rooms during the night from Sunday to Monday. EFS initially said the affected samples were kept as part of a transfusion safety surveillance system but later acknowledged that frozen plasma intended for transfusion was also targeted. The piece is tagged under cybersecurity and framed as a serious cybercriminal incident affecting blood-product storage infrastructure.
Confidence: High
Incident clearly involves a malicious cyberattack manipulating operational technology that controls health-sector cold storage, fitting Cyber & Information Warfare > Cyber Attacks against critical infrastructure. The primary subject is the hostile act itself, justifying HYBRID_SIGNAL. Reporting outlet is known for fact-checked investigative work, but full technical details and attribution are not provided, hence moderate information credibility.
