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 discard food, the Korea Times reports. The attack, which also reached US mainland military bases, involves hacking remote control systems to raise temperatures to 50 degrees Celsius, disrupting food supply chains. Russian sabotage is being considered as a possible cause, according to Chosun Ilbo. The incident follows a previous attack in France and highlights vulnerabilities in internet-connected industrial equipment, as noted by the Korea Times. Korean reaction focuses on broader cybersecurity concerns: 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 after a series of cyberattacks on financial firms, the Korea Times reports.
