As a massive personal information leak unfolded at Coupang, a leading domestic e-commerce company, domestic cybersecurity stocks were strong on the morning of the 1st.
As of 9:05 a.m. on the 1st, Genians was trading on KOSDAQ at 21,950 won, up 2,620 won (13.55%) from the previous trading day.
At the same time, shares of SOFTCAMP, CYBERONE, SANDS Lab, Raonsecure, and HANSSAK—picked as related cybersecurity stocks—were also rising.
Earlier, on the 29th, Coupang posted a notice saying it had confirmed that about 33.7 million customer accounts were exposed without authorization. The exposed information includes names, emails, phone numbers, and addresses, and Coupang said it believes there was unauthorized access to personal information via overseas servers starting on June 24.
The scale of this data breach surpasses SK Telecom's personal information leak incident (about 23.24 million people), which led to the largest-ever penalty surcharge (134.8 billion won) from the Personal Information Protection Commission for a personal data protection violation.
The Personal Information Protection Commission is currently conducting a related investigation. The Ministry of Science and ICT has formed a joint public-private investigation team to analyze the cause of the incident and draw up measures to prevent a recurrence, according to reports.
