It now turns out, according to FXN report, that the US official who "unmasked" the names of multiple private citizens affiliated with the Trump team is someone "very well known, very high up, very senior in the intelligence world."

As Malia Zimmerman and Adam Housley report, intelligence and House sources with direct knowledge of the disclosure of classified names (yes, yet another "unnamed source") said that House Intelligence Committee Chairman Devin Nunes, now knows who is responsible - and that person is not in the FBI (i.e. it is not James Comey)

Housley said his sources were motivated to come forward by a New York Times report yesterday which reportedly outed two people who helped Nunes access information during a meeting in the Old Executive Office Building. However, Housley's sources claim the two people who helped Nunes "navigate" to the information were not his sources.
