What happened

  1. A system anomaly was detected and traces of unauthorized access from outside were found. The network involved was cut off at once. [2]

  2. TwitCasting was taken down for emergency maintenance, together with the corporate site and others. [1] [2]

  3. After a notice on its official X account, the company disclosed the incident in a stock exchange filing. Updates will come through filings and its official X account for now. [1] [2]

Impact

The extent is still being investigated. The service will only return once it is confirmed safe, which is expected to take time, and no restart date has been set. The effect on earnings is also under review. [1] [2]

Response

An in-house expert team is leading the investigation into the extent. Questions are taken by email. [2]
