Any connection to Mukhabarat?
Probably in the root.
Mukh is brain
Makhab is Hidden
Mukhabarat is "intelligence", but please be careful with that. It has overwhelmingly negative connotations.
Istkhabarat is also "intelligence", but I have not heard it have such a "dread factor" as the Mukhabrat.
Its sort of like knowing what Geheime Staatspolizei translates as, and knowing what it means.
مخبر is probably culturally different to مصدر الاستخبارات البشرية
(Masdar al-Istkhabarat al-bashret) source of human intelligence
to جاسوس (Jasus - Spy).
No one wants to be around when the word khain خائن
Never ends well (edited to add, "Traitor")
