Unauthorized external access confirmed; further attacks blocked, operator says
Kakao Work, the tech giant's workplace messaging service, was hit by an external cyberattack that exposed the personal data of some users, including names, contact details, work email content and original file attachments.
The operator of Kakao Work said it has blocked the unauthorized access route and is investigating the extent of the breach.
DK Tech In, the company that runs Kakao Work, announced Thursday that "an unauthorized external intrusion into the Kakao Work system occurred on Monday, resulting in the leak of personal information belonging to some users."
DK Tech In said it removed the external access route immediately upon detecting the breach, blocking further attacks and strengthening system security measures. The company is currently conducting a comprehensive review of its systems to determine whether additional data was exposed and to assess the full scope of the damage.
The leaked data included names, phone numbers and email addresses, as well as the full text of emails and their original attachments.
DK Tech In also urged users to be cautious of text messages or emails impersonating Kakao Work, and to avoid opening links or attachments from unverified sources. The company particularly warned users to watch out for phishing attempts requesting passwords or authentication codes.
