SETTRA is a ransomware/extortion threat actor observed in ransomware claims reporting and in a claimed compromise of Pi Mobile Technology, a subsidiary of Taiwan-based e-commerce company PChome Online. In week 26 of 2026, eCrime.ch recorded 11 SETTRA claims, noting the group was absent from the prior week’s ranking and entered directly at that activity level; the report also cautioned that such figures are self-announced by cybercriminal groups and are not formally validated. Separately, Taiwan News reported that Settra claimed it had compromised PChome’s systems and obtained internal documents and user data. PChome stated its preliminary review found no intrusion affecting its main website or core systems, so the claim remained under investigation. Based on the referenced reporting, techniques identified as relevant to the incident were T1078 (Valid Accounts) and T1530 (Data from Cloud Storage). No indicators of compromise or CVEs were provided in the content. Known alias in the provided content: Settra / SETTRA.
