SK Telecom probes cyberattack after weekend breach
Legal penalties loom for SK Telecom after data breach review.
SK Telecom, South Korea’s largest mobile operator, has confirmed that hackers breached its internal systems, possibly exposing sensitive data linked to USIM cards.
The company discovered the intrusion late Saturday night and responded swiftly by removing malware and isolating affected equipment.
Investigations are underway, with the Korea Internet & Security Agency and the Ministry of Science and ICT examining the breach’s scope and root cause.
Officials have asked SK Telecom to preserve evidence and cooperate with technical experts sent to the site.
In response, SK Telecom is boosting defences against USIM-related fraud and offering a free protection service to concerned users.
Legal consequences could follow if the breach is found to have violated data protection laws, with potential fines reaching up to 3 percent of related revenue or 50 million won.
