[Italy announces preliminary investigation results of cyber attacks on supermarket refrigeration equipment] On November 4, the Italian government held a meeting at the Prime Minister's Office in response to the cyber attack on supermarket refrigeration equipment. Officials including the Italian Minister of Agriculture, the Director of the National Cyber ​​Security Agency and the head of the intelligence agency attended the meeting. Preliminary investigation results show that most of the affected facilities use old security systems, with control interfaces directly exposed to the Internet and insufficient identity authentication mechanisms. There have been no known cases of thawing frozen food endangering public health. Italy's interior minister said the attacks occurred in multiple European countries and may have been a coordinated operation. At present, the identity of the attacker and his motive have not yet been determined. (CCTV News)
