Cellcom Confirms Cyberattack Caused Outage with No Data Breach; SK Telecom Malware Breach Since 2022 Spurs 1,000-User Lawsuit Seeking 1 Million Won Each

Cellcom, a wireless carrier, confirmed that a cyberattack was responsible for a week-long outage affecting its network. Initially attributing the disruption to a technical issue, the company later acknowledged the incident as a cyberattack and reported that hackers continue to attempt to breach its systems. Despite the attack, Cellcom stated there is no evidence that customers' personal information, including names, addresses, and financial data, was compromised. Meanwhile, in South Korea, SK Telecom (SKT) is facing a separate cybersecurity incident involving a malware breach that reportedly began in 2022. A joint public-private investigation into the SKT hacking case has yet to identify the perpetrators. The incident has prompted over 1,000 SKT users to announce a collective lawsuit seeking damages of 1 million won (approximately $850) per person, citing the theft of SIM card information. Both cases highlight ongoing cybersecurity challenges faced by major telecommunications providers.
