Is dox a new word?

I'm curious, could you clarify whether 'dox' is indeed a new word that has entered our linguistic lexicon? It seems to be cropping up in various contexts, particularly in the realm of cryptocurrency and finance, but I'm unsure if it's a recent addition to the English language or simply a term that's been coined for specific industries. Could you shed some light on the origins and usage of 'dox' as a word?
