すべての人が同じ情報を失ったわけではない
検知された時刻は侵入の開始時刻ではない
サービス停止後も続く警告
同公社は、ボイスフィッシングやスミッシング、つまり詐欺目的の電話やテキストメッセージに特に警戒するよう利用者に呼びかけた。この警告は、露出した情報が利用者を狙うために使われる可能性を踏まえたものだ。そうした詐欺がすでに起きたとの認定ではなく、公表された報道にも、金銭的被害が確認されたとの評価はない。13
聯合ニュースが報じた発言を英訳したものによると、名前が公表されていないKOMSCO関係者は「国民の皆さまに深くお詫び申し上げます」と述べた。この関係者は、個人情報の保護を委ねられた公的機関としての責任を認め、さらなる被害の防止と利用者の保護に全力を注ぐと約束した。2

放送時の内容
- An outsider viewed personal information belonging to 3,083 Chak users.
- South Korea's public voucher platform has restored service, but exposed details could still be used to target its customers. The corporation running it has apologized and warned users about fraudulent calls and texts.
- How did the outsider get in, and what risk remains after the service restarted?
- Chak is a mobile platform for local-currency vouchers in South Korea. The Korea Minting and Security Printing Corporation, known as KOMSCO, operates it. Its investigation found that someone outside the organization accessed the system without permission and viewed personal information.
- The affected population stood at 3,083 at six in the morning on November 14, 2026, Korean time. That gives a precise figure for the earlier description of about three thousand people. The assessment could change as the investigation continues.
- Most affected users had only a small number of information fields exposed. But the details varied from person to person, so the overall list of exposed information doesn't tell an individual customer exactly what someone saw about them.
- For 3,072 people, the outsider viewed two or fewer information fields. Another 11 people had three or four fields viewed. Those two groups make up the total, and show why the incident's full list shouldn't be applied to every customer.
- Some two-field combinations included a name and birth date. Another example paired connecting information, identified as C I, with an encrypted card number. KOMSCO described the card numbers as encrypted, but hasn't explained how strong that protection was.
- Names and birth dates were among the exposed details, along with mobile telephone numbers and bank account numbers. The incident also involved connecting information, email addresses and encrypted card numbers. These seven categories describe the exposure across the platform, with different combinations affecting different people.
- A person with a name exposed may face a different risk from someone whose account information was viewed. Customers therefore need to know which details were involved in their own case. KOMSCO says it's informing customers about the facts, the information viewed and precautions against further harm.

- KOMSCO first detected abnormal access at about nine thirty in the morning on November 13. That tells us when it spotted the warning signs. Investigators still have to determine when the outsider first entered the system and how long the access lasted.
- KOMSCO blocked internet addresses suspected of involvement, then blocked overseas access altogether. It identified the targeted server and suspended the affected service. After emergency security measures, it restored normal service. The overseas block was part of containment; the attacker's identity remains unknown.
- The corporation reported the incident to the Korea Internet and Security Agency, known as KISA, and cooperated with relevant authorities. It says it's strengthening security to prevent further unauthorized access and misuse of the information already exposed.
- An unnamed KOMSCO official said, “We deeply apologize to the public.” The official acknowledged the responsibility of a public institution entrusted with personal information, and pledged to focus the corporation's capabilities on protecting customers and preventing further harm.
- KOMSCO's warning now reaches beyond the platform itself. It's asking users to be particularly alert to voice phishing and smishing. Those terms mean fraudulent telephone calls and text messages, which could use exposed personal details to target customers.
- The warning concerns possible follow-on harm. KOMSCO hasn't announced a confirmed financial-loss assessment or said whether the exposed information has been misused. Restoring the voucher service can't retract personal information that an unauthorized outsider has already viewed.
