On February 23, 2024, South Korean company kc.co.kr appeared on an underground ransomware leak site, claiming that its internal files had been exfiltrated during a ransomware attack. The listing, hosted on a Tor onion address and indexed by ransomware.live, states that the attackers stole corporate data from the firm, which generates roughly $650 million in annual revenue. The number of individuals whose information may be inside those files remains unknown.

Details in the Leak Listing
The primary disclosure on the ransomware group’s leak site indicates that kc.co.kr suffered a ransomware intrusion and that attackers successfully exfiltrated internal files. No specific volume of records, types of documents, or list of data fields is provided. The entry simply states the exfiltration occurred and gives the company’s approximate revenue and South Korean location. The disclosure does not state whether customer records, employee personal data, or partner contracts were taken, nor does it list any ransom demand or negotiation status.
February 23, 2024 marks the first public confirmation of the incident through the leak portal. Because ransomware operators routinely publish only a fraction of stolen material as proof, the full scope of what was taken is not yet known.
Why This Matters for You and Your Family
When a company the size of kc.co.kr loses control of internal files, anyone whose personal information touched that organization faces heightened risk. If you or your family members have done business with the company, worked there, or appear in vendor records, your details could sit inside the stolen archive. Even without exact record counts, the exposure of corporate files often includes spreadsheets containing names, addresses, national identification numbers, contact details, and financial information. Once that material leaves the victim’s control, it can circulate for years on dark-web forums and private Telegram channels.
