Listed below is a timeline of the ransomware attack incident, the investigation, and the results of the investigation:

1. Background
A Company employee downloaded a software required for business from an external website, which had been tampered with so as to simultaneously download a software program that would serve as the entry point for ransomware infiltration.

When the above-mentioned unauthorized access into its network was confirmed, the Company took various measures including immediately shutting down portions of its internal system and restricting access from outside. concerned authorities but also has been carrying out appropriate and necessary responses and investigations by involving external security specialists.


As of today, following the implementation of security measures, all the internal systems of the Company are more or less normalized.
