Recent cyber-attacks targeting French blood storage refrigeration units attempted to alter internal temperatures.
Swift staff intervention prevented any loss of medical supplies, as researchers investigate the broader implications of connected appliance vulnerabilities.
According to the French Blood Service, the perpetrators managed to interfere with the cooling mechanisms and raise the temperature, but staff intervened in time and protected the stocks. There were no losses of blood products or a risk to public health. Until this incident, such attacks on refrigerators were known to only affect supermarkets.
Who is behind the attacks?
Russian hacker activist groups such as NoName057(16) and Z-Pentest Alliance have reported online that they have breached Danfoss, raising suspicions that they are responsible for the refrigerator attacks. However, experts have serious doubts whether these groups actually carried out the attacks.
Analysts say the incidents could be the work of groups from Iran, hackers linked to foreign governments, or even teenagers playing pranks. Cybersecurity firms have set up digital traps to monitor how the attackers try to exploit the refrigerators' software.
Design and research
Experts point out that the fact that the refrigerators were affected simultaneously seems to have been done at night to cause maximum damage, which shows planning and coordination. The systems used in the refrigerators had weak protection and the methods used were already available on the internet.
