Ask what Korea is talking about.

Korean outlets report that Korean Air and Asiana Airlines customer data was leaked after a hacking of a system operator (a partner company). The Hankyoreh says the leak in Vietnam exposed nine years of Korean airline passenger records, and 한국경제 reports the breach as "협력사 해킹 피해" (partner company hacking damage). The exact number of affected customers is not given in the supplied documents. Korean reactions focus on the scale of the exposure and the role of the third-party operator, though specific public commentary from blogs or cafés is not included in the documents.
