โ๏ธ ๐ก๏ธ This week, hackers took remote control of refrigeration systems across hundreds of French supermarkets, driving temperatures up to 50ยฐC (122ยฐF) overnight.
The result: ๐๐ผ๐ป๐ป๐ฒ๐ ๐ผ๐ณ ๐ณ๐ฟ๐ฒ๐๐ต ๐ฎ๐ป๐ฑ ๐ณ๐ฟ๐ผ๐๐ฒ๐ป ๐ณ๐ผ๐ผ๐ฑ ๐๐ฝ๐ผ๐ถ๐น๐ฒ๐ฑ, ๐๐ฒ๐๐ฒ๐ฟ๐ฎ๐น ๐ฟ๐ฒ๐ฝ๐ผ๐ฟ๐๐ฒ๐ฑ ๐ณ๐ถ๐ฟ๐ฒ๐, ๐ฎ๐ป๐ฑ ๐น๐ผ๐๐๐ฒ๐ ๐ฒ๐๐๐ถ๐บ๐ฎ๐๐ฒ๐ฑ ๐ถ๐ป ๐๐ต๐ฒ ๐บ๐ถ๐น๐น๐ถ๐ผ๐ป๐ ๐ผ๐ณ ๐ฒ๐๐ฟ๐ผ๐. The damage became apparent through the fires that broke out, or the following morning, when staff opened the fridges and were met with a blast of warm air.
The attack reached the refrigeration controllers themselves, the systems that regulate compressors and defrost cycles. If a system is responsible for operation and monitoring its own condition, there is ๐ป๐ผ ๐ถ๐ป๐ฑ๐ฒ๐ฝ๐ฒ๐ป๐ฑ๐ฒ๐ป๐ ๐ฐ๐ต๐ฒ๐ฐ๐ธ in place. The moment that system is compromised, both the ๐ฐ๐ผ๐ป๐๐ฟ๐ผ๐น ๐น๐ผ๐ด๐ถ๐ฐ ๐ฎ๐ป๐ฑ ๐๐ต๐ฒ ๐๐ฎ๐ฟ๐ป๐ถ๐ป๐ด ๐๐ถ๐ด๐ป๐ฎ๐น ๐ฑ๐ถ๐๐ฎ๐ฝ๐ฝ๐ฒ๐ฎ๐ฟ together. This leaves no way to detect that anything has gone wrong.

The moment a reading leaves its defined range, an automatic alarm goes out by email, SMS or app push to staff, independently of whether the controller itself is still trustworthy. That is the principle behind systems such as testo Saveris Food: ๐ฎ ๐๐ฒ๐ฐ๐ผ๐ป๐ฑ, ๐ถ๐ป๐ฑ๐ฒ๐ฝ๐ฒ๐ป๐ฑ๐ฒ๐ป๐ ๐๐ฒ๐ ๐ผ๐ณ ๐ฒ๐๐ฒ๐ ๐ผ๐ป ๐๐ต๐ฒ ๐ฝ๐ฟ๐ผ๐ฑ๐๐ฐ๐, ๐ป๐ผ๐ ๐ผ๐ป ๐๐ต๐ฒ ๐ฒ๐พ๐๐ถ๐ฝ๐บ๐ฒ๐ป๐.

The incident shows that food safety has many different facets and is under attack from various quarters. ๐๐ถ๐
