Ask what Korea is talking about.

A cyberattack on supermarket refrigeration systems spread across Europe on Monday, hitting fridges and freezers from Sweden to Belgium and forcing stores to throw away food, the Korea Times reports. The attack, which began in France in October, has expanded to Sweden, Belgium, Ireland and other countries, with hackers remotely raising temperatures to 50 degrees Celsius and forcing disposal of millions of euros' worth of food, according to Chosun Ilbo. The attacks have also reached a U.S. mainland military base, and Russian sabotage is being discussed as a possible cause, Chosun reports. Korean officials are responding: President Lee Jae Myung ordered a review of plans for a government-wide cybersecurity agency, and the NIS asked 2,100 public institutions to conduct emergency checks following a series of cyberattacks on financial firms, the Korea Times reports.
