SK Telecom, South Korea’s largest telecom company, disclosed a data leak involving a malware infection.
SK Telecom is South Korea’s largest wireless carrier — it has tens of millions of subscribers and holds roughly half of the local market.
The company revealed on Tuesday in a Korean-language statement posted on its website that it detected an intrusion on April 19. An investigation showed that the attackers deployed malware and managed to obtain personal information belonging to customers.
Following the incident, SK Telecom is offering customers a free SIM protection service designed to prevent SIM swapping, which suggests that the leaked data could be leveraged for such activities.
Korean telecom company KT Corporation sent malware to its subscribers who use Webhard's Grid Service peer-to-peer sharing program to hide their files and stop them from using the service.
A North Korean hacking group had stolen a massive amount of personal information from a South Korean court computer network, probe results showed on Saturday.
A total of 1,014 gigabytes worth of data and documents were leaked from Seoul's court computer network between January 2021 and February 2023 by the hacking group, presumed to be Lazarus, according to the joint probe by the police, the prosecution and the National Intelligence Service.
The signees, which already included about a dozen other nations, agree to establish “robust guardrails and procedures" around spyware, while preventing the export of technology that will be used for malicious cyber activity.
