How do hackers operate to sabotage cooling systems and why can the temperature rise so high?

Cybersecurity experts warn that hackers can exploit management accounts of cooling systems, leading to significant failures in supermarkets like Delhaize and Carrefour. These incidents, reported in Belgium and abroad, suggest a coordinated cyberattack rather than mere IT issues. Hackers can gain access through unchanged admin passwords, allowing them to manipulate settings and cause temperature spikes in cooling units. This can result in substantial financial losses due to spoiled goods. While financial gain is a likely motive, some speculate it could also be a hybrid attack aimed at causing public panic. The recent incidents highlight the critical need for improved cybersecurity measures in businesses.
