90,000 Golf Club Members' Data Leaked in South Korea; Hackers Demand Ransom

Personal information belonging to nearly 90,000 members of a golf club in Jincheon, South Korea, has been compromised in a significant data breach. The incident prompted an immediate police investigation after the club received a threatening email.

On July 27, an unidentified individual contacted the golf club, instructing them to check their email. The email contained a demand for money, stating that the sender had hacked the customer information and would release it if their demands were not met. The sender also provided a Telegram link, suggesting the use of the platform for communication or further demands.

Golf club officials promptly reported the incident to the police and the Korea Internet & Security Agency (KISA). Authorities estimate that the data of around 90,000 members has been leaked. The compromised information includes names, dates of birth, addresses, company affiliations, and phone numbers. Worryingly, some members' resident registration numbers may also have been exposed.

The Jincheon Police Station initially handled the case before transferring it to the Chungbuk Provincial Police Agency. Investigators are currently working to determine the exact method of the data leak and other specifics of the incident. The breach underscores ongoing concerns about cybersecurity and the protection of sensitive personal data in South Korea.
