Background
SecurityWeek reports that GoldenSpy appeared in a campaign thought to have begun in April 2020, though certain samples indicate the threat may date back to at least December 2016. One affected victim, a global technology vendor doing government work in the US, Australia, and UK that had recently established a presence in China, was compromised after installing "Intelligent Tax," software from Aisino Corporation's Golden Tax Department that a local bank mandated for paying local taxes. The program functioned as promised, but it was also found to install a concealed backdoor letting remote operators run Windows commands or upload and execute files.
