page 214. (if no other OS uses the same icons ofc)
I haven't checked the report, but based on the context, I assume there is a screenshot showing black & white icons, akin to those of our default apps.
This does not mean the devices are running GrapheneOS. We are aware of many GrapheneOS forks, including sketchy ones adding security theater etc.
Assuming something like this is GrapheneOS just based on the icon would be the wrong assumption to make if it's solely based on that, especially since we know these other forks doing sketchy stuff exists, because something that's compromised on these OSes may not be the case on GrapheneOS.
By that I mean, maybe these forks are adding features in an incorrect insecure way, or are otherwise removing things we've added, including low-level hardening, modifying our work in a misguided way, etc.
It doesn't have the mean that they're actively maliciously making the fork insecure. It could also be due to incompetence / lack of care.
Hope that makes sense.
