Threat Group Cards: A Threat Actor Encyclopedia Archived: 2026-04-05 16:10:13 UTC Home > List all groups > List all tools > List all groups using tool HiddenLotus Tool: HiddenLotus Names HiddenLotus Category Malware Type Backdoor Description (Malwarebytes) So HiddenLotus didn’t seem all that interesting at first, other than as a new variant of the OceanLotus backdoor first seen being used to attack numerous facets of Chinese infrastructure. OceanLotus was last seen earlier this summer, disguised as a Microsoft Word document and targeting victims in Vietnam. But there was something strange about HiddenLotus. Unlike past malware, this one didn’t have a hidden .app extension to indicate that it was an application. Instead, it actually had a .pdf extension. Yet the Finder somehow identified it as an application anyway.
