Cyberattack threatens utterly critical infrastructure in Japan: KFC

The crippling high-consequence attack on vital infrastructure that cybersecurity experts have warned about for years is upon us, in the form of an incident that may force KFC to close some stores in Japan. Colonel Sanders himself is not the victim here. That role goes to Nichirei Group, a Japanese purveyor of frozen foods and super-chill logistics services that move them around. Nichirei Group on Monday posted a notice [PDF] in which it admitted system failures caused by unauthorized access have occurred." The failures meant the frozen food concern could not arrange shipments to or from its refrigerated warehouses or conduct its other operations. Shortly after Nichirei Group revealed its difficulties, KFC Japan warned customers that delivery of ingredients to its stores would likely be affected. The chicken chain therefore stopped taking orders through its app and website and said it may need to limit menu items and opening hours. Some stores may be closed depending on the availability of ingredients," the company said. On Wednesday, Nichirei Group confirmed the cause of the outage was a cyberattack and admitted attackers accessed a server that stores personal information. The Group declined to offer any detail on the incident to prevent further damage." The company hopes to resume operations on Friday. That Nichirei Group is unable to provide some services suggests a ransomware attack has made some data unavailable. The mention of further damage" suggests that discussing whatever happened could divulge clues about security weaknesses that would allow further attacks, perhaps directed at the Group's clients. KFC Japan hasn't posted any information about store closures. Indeed, the company continues to promote summer menu items such as a Japanese-style citrus and chicken combo that the chain says is refreshing to eat even in the heat of summer. The Register's Asia-Pacific bureau will not venture to Japan to assess the impact of this incident, or try the burgers: At times like this, with critical infrastructure under stress, that's just the right thing (not) to do.
