[MCU] Seriously, why the hell isn't anybody else dealing with The Hand?

How is it possible that two otherwise average citizens like Luke Cage and Jessica Jones could just stumble upon a worldwide secret society that has fingers in everything, but not SHIELD or The Avengers? Why doesn't anybody know about them?

The Hand stay under the radar. They have links to organised crime and business, but they don't try to destroy the world or fire blue lasers at the sky; they work low-level, on the streets of New York (and a thousand other cities around the globe). Their latest scheme would have destroyed much of New York, but it would have been the first such major act of devastation by them since Chernobyl.

If the Avengers or SHIELD were in the habit of investigating street-level crime, they'd have found the Hand fairly quickly. But they were too busy saving the world and fighting HYDRA.
