Hackers can attack routers and home appliances after breaking into supermarket refrigerators, the European Cyber Security Agency said as reported by the South China Morning Post. The department's director general, Johan Lepassar, urged European countries to increase investment in defense against cyber threats. "Every single service that you depend on as a citizen, as a person, contains a layer where there is a digital element, a piece of code that, if not protected, can be hacked," he said.
