This is an analysis of a file they obtained in 2013, which has elements that were revealed in the Shadow Brokers files. The list of victims is from those files, too, from 2017.
Most home routers these days have firewalls enabled and no amount of NSA technical wizardry is going to get past those.
The "backdoor" is refered from the pangulab report[1] but I think it actually means "virus" in common sense. (Maybe security people speek different technical jargons than linux users?)

So basically NSA spies also on scientists and their research.
