Core Event
South Korea’s Foreign Ministry announced on July 21 that a cyberattack on the Korea National Diplomatic Academy’s online education system exposed a “significant” amount of data. The breach exploited an unknown “zero-day” software vulnerability and weak security configurations, allowing attackers to control a server from April–May 2025 until February 2026, when suspicious activity was detected and the system was blocked. Authorities have not yet identified the full scope of the leak or the specific information compromised.
Data & Statistics
- The academy’s platform stored training videos, course-administration details, participants’ names and user IDs.
- Dong-A Ilbo, citing government sources, reported that personal information of roughly 6,000 current and former diplomats and officials seconded from other ministries may have been compromised.
Official Statements & Responses
Ministry spokesperson Park Il told a briefing that the leak was of “considerable scale” but that “no misuse of leaked data had been confirmed.” He added that investigators have “insufficient technical evidence to determine who was behind the attack,” while emphasizing that the government is not ruling out any possibilities, including foreign-based hacking groups. The ministry said it is working with relevant agencies to assess the breach’s full extent and to strengthen internal cybersecurity systems.
