Nearly 40 million user accounts of Korean streaming platform Tving were compromised in a massive data breach stemming from a hacking incident reported in June, a joint investigation showed Thursday.
Summary
The Ministry of Science and ICT announced the results of a three-month government-civilian investigation into the breach at Tving, an online video streaming platform operated by entertainment giant CJ ENM. A total of 39.54 million user accounts and 361 technical assets, including source code, were found to have been compromised in the breach reported on June 1, although the account figure includes multiple accounts held by the same users, the ministry said. Tving has since strengthened its security measures, and no signs of additional attacks have been detected so far, it noted.
By registration method, they included 7.26 million accounts registered directly with Tving, 8.63 million CJ ONE integrated membership accounts and 22.47 million accounts created through social media log-in services, including Naver, Kakao, Facebook, Apple and X.
KazaSec's take
Incidents like this rarely start with the headline event itself, they usually trace back to an exposed remote-access endpoint, an unpatched perimeter system, or a credential phished weeks earlier. The organizations that recover fastest are the ones that tested their defenses and their incident response plan before they needed them.
