In brief
A publicly posted computer file containing personal information on President Lee Jae‑Myung and an entourage of 167 officials during a June overseas trip triggered a sharp rebuke from the People Power Party (PPP). The PPP called the leak a "security disaster" and urged an apology, while the ruling Democratic Party insisted the incident was being politicised. Police have opened a formal inquiry, and the presidential office says it has taken measures to prevent further breaches.
On November 3, 2026, Seoul became the center of a national security controversy when a computer file publicly released online contained personal data on 168 individuals, including President Lee Jae‑Myung, his wife, medical staff, security personnel, and aides who accompanied him on an overseas trip in June. The file was uploaded to a publicly accessible website, prompting immediate concern from South Korea’s main opposition People Power Party (PPP).
Opposition Condemnation
The PPP’s spokesperson, Cho Yong‑sool, slammed the presidential office for the leak, calling it a “security disaster.” He said the data release exposed key information about the president’s trip in a manner that could be likened to “leaving the door wide open to an enemy or a terrorist group.”* Cho highlighted that the identities of security officers and medical aides were also disclosed, which he said heightened the seriousness of the breach.
"The data leak of key information related to a presidential overseas trip to the public amounts to a security disaster akin to leaving the door wide open to an enemy or a terrorist group," the spokesperson said. He further added, “What is more concerning is that the identities of security personnel, medical staff and aides assisting the president were also exposed.”
Following Cho’s remarks, PPP leader Jang Dong‑hyeok posted on Facebook a pointed comment: “It is now the presidential office’s turn to go down?”* Jang reiterated President Lee’s prior statements that penalties for personal data breaches should be tough enough so companies fear losing business.
Government and Police Response
DP floor spokesperson Lee Ju‑hee countered the opposition’s accusations by labeling the PPP’s criticism as politicisation. She said the ruling Democratic Party had acted promptly by deleting the leaked information from the website and conducting checks to see if additional data had escaped. Lee urged the PPP to “wait for the results of the government investigation” before inflaming the public’s anxiety.
“The government immediately deleted the information posted on the website and took proactive measures to prevent further damage, including checking whether additional data has been leaked,” Lee said. “For the PPP to be a responsible opposition party, it should stop turning everything into a political issue and fueling public anxiety.”
Cheong Wa Dae, the presidential office, confirmed that it has taken necessary measures after becoming aware of the data leak. The office also stated that police have now launched a formal investigation into the incident. Initial reports suggest the leak may have resulted from an internal misstep or an automated security scan, though the exact cause is still under examination.
The situation has prompted calls from various sectors for stricter data protection laws. PPP officials reiterated that the incident demonstrates a failure in the presidential office’s lax discipline and that accountability for those responsible is essential. Meanwhile, the Democratic Party has urged a balanced approach, insisting the focus should be on improving safeguards rather than turning the leak into a political scorecard.
As the investigation proceeds, both parties remain prepared to act: the PPP seeks a public apology and systemic reforms, while the DP emphasises cooperation with law‑enforcement and an integrity‑building policy. For now, the leak shines a spotlight on the vulnerabilities of presidential personal data and the broader need for heightened cyber‑security in South Korea’s high‑level government operations.*
