InPsytech says only its ERP was encrypted and the isolated R&D network was not reached

According to iThome, on the evening of September 1, emerging stock semiconductor IP company InPsytech (7898) issued a cybersecurity material announcement on the Market Observation Post System (MOPS), stating that its ERP system suffered a hacker encryption attack; after its information security unit detected anomalies in the ERP system and confirmed an encryption attack, it immediately launched comprehensive inspections, incident investigations, and protective operations, and is continuing to verify the scope of impact and conduct root cause analysis ^[1]. Regarding the impact of the incident, InPsytech's preliminary assessment indicates no material impact on its finances, business, or operations ^[1]. Unlike most material announcements for encryption attacks, InPsytech specifically noted that its ERP and R&D environments are managed through segmented isolation—with separate controls for network environments, system access permissions, and data storage—so the incident only affected the ERP system and no evidence was found of the attack spreading to R&D information systems ^[1].
