To further strengthen the security of the WCS platform and protect our customers against increasingly sophisticated cyber threats, Woori Bank will introduce an enhanced login authentication process effective 6 November 2026.
Recent cybersecurity incidents across the financial industry have highlighted the importance of stronger authentication and access-control measures.
While no impact related to these incidents has been identified within Woori Bank to date, we believe that proactive security enhancement is essential in today's evolving threat environment. As part of our ongoing commitment to safeguarding customer information and maintaining a secure banking environment, we are implementing an additional verification step for WCS users.
