DOUZONE BIZON server breach raises wider concerns over client data exposure
Impact: As of 5 November, 28 companies and institutions had issued notices of possible personal data leaks; the actual scale of any leak remains unconfirmed
Two security breaches were confirmed at DOUZONE BIZON, raising the possibility that personal data belonging to client companies and third parties whose data those clients held may have been leaked. Historical records of companies whose services had ended may also have been affected, and as of 5 November, 28 companies and institutions had issued notices of possible data leaks. DOUZONE BIZON voluntarily reported the incidents to the Korea Internet & Security Agency (KISA) and the Personal Information Protection Commission (PIPC) and disclosed progress on security investments totalling 16 billion won. The government deemed the incidents serious and launched a joint public-private investigation, while whether data was actually leaked and the extent of any leak remain under investigation.
