Grey Market

Definitions

1. The unofficial but not necessarily fully illegal market for goods, software licenses, credentials, or hardware resold outside authorized channels. In security contexts, grey-market activity matters because it can involve diverted devices, abused trial accounts, or resold access with little provenance.

   In plain English: An unofficial resale market outside normal authorized distribution channels.

   Example: "The cheap hardware token turned out to come from the grey market, with no trustworthy chain of custody."
