In both his twitter (err, X) thread and in a subsequent posting he provided a comprehensive background and triage of the malware dubbed SpectralBlur. In terms of its capabilities he noted:

SpectralBlur is a moderately capable backdoor, that can upload/download files, run a shell, update its configuration, delete files, hibernate or sleep, based on commands issued from the C2. -Greg
He also pointed out similarities to/overlaps with the DPRK malware known as KandyKorn (that we covered in our “Mac Malware of 2024” report), while also pointing out there was differences, leading him to conclude:

We can see some similarities ... to the KandyKorn. But these feel like families developed by different folks with the same sort of requirements. -Greg
