SK Telecom investigates data breach after cyberattack
Investigation launched after SK Telecom suffers data breach
South Korean telecom leader SK Telecom has confirmed a cyberattack that compromised customer data following a malware infection.
The breach was detected on 19 April, prompting an immediate internal investigation and response. Authorities, including the Korea Internet Security Agency, have been alerted.
Personal information of South Korean customers was accessed during the attack, although the extent of the breach remains under review. In response, SK Telecom is offering a complimentary SIM protection service, hinting at potential SIM swapping risks linked to the leaked data.
The infected systems were quickly isolated and the malware removed. While no group has claimed responsibility, concerns remain over possible state-sponsored involvement, as telecom providers are frequent targets for cyberespionage.
It is currently unknown whether ransomware played a role in the incident. Investigations are ongoing as officials continue to assess the scope and origin of the breach.
