In a recent cybersecurity incident emerging from Tokyo, Japan, technology behemoth LY Corp. disclosed a Line Messenger data breach, exposing 440,000 pieces of personal data, with over 300,000 linked to the messaging app.
The Line Messenger security breach reportedly happened due to unauthorized access to an affiliate’s computer system in October. As of now, there have been no reported instances of misuse stemming from the breach, according to LY Corp.
Line Messenger data breach explained
The compromised data related to Line services did not encompass sensitive information such as bank accounts, credit cards, or chat messages within the Line app.
The leaked data in this Line Messenger security breach primarily contained details about the company’s business associates and employees, encompassing email addresses, names, and affiliations. LY Corp., formed in October through the merger of Z Holdings Corp. and its subsidiaries Yahoo Japan Corp. and Line Corp., attributed the breach to malware infecting a computer owned by an employee of a subcontractor utilized by the company’s South Korea-based affiliate, Naver Cloud Corp.
The Cyber Express sought clarification from the organization regarding the alleged Line Messenger data breach. However, as of the time of writing, no official statement or response has been received, leaving the claims regarding the Line Messenger data breach unverified.
What’s next for the Line Messenger data breach?
Kyodo News reported that Naver Cloud and LY share an internal system for managing employee and personnel information, governed by a common authentication system. This shared system inadvertently facilitated unauthorized access to LY’s internal infrastructure.
LY Corp. is actively reaching out to individuals it believes may be at risk of harm due to the data leak, including users, business partners, and customers. Despite assertions of a Line Messenger data breach, the company has not provided specific details.
Given Line’s global operations, the exact location of the breach remains undisclosed, adding to the uncertainty surrounding the origin of the Line Messenger data breach.
This remains a developing story, and The Cyber Express continues to closely monitor the Line Messenger data breach. Updates will follow as more information becomes available or upon confirmation from the involved organization.
