I've bought SRAM force e1 groupset components (not rim brake) on AliExpress from anaracee cycling store. It's definitely genuine, connects to sram app, receives firmware updates, etc. It would be extremely difficult to fake this sort of thing. Does not come in consumer packaging however.
Be more careful about things like chains, cassettes, pedals, etc, and other obvious counterfeits such as s-works helmets, darimo components, s-works/colnago/factor frames, etc.
