According to iThome, as publicly traded companies in Taiwan face frequent cyberattacks, how enterprises determine whether a cybersecurity incident is material enough to require public disclosure has been a key question over the past two years [1]. When iThome recently reported on the 2023 cybersecurity incident landscape for listed companies, the Taiwan Stock Exchange (TWSE) noted that explicit rules had been established in the updated Material Information FAQ released in January of this year [1]. Following that earlier report, the Financial Supervisory Commission (FSC) and the Taipei Exchange (TPEx) released further details in March [1].
