Who approved the unmasking of Flynn's name?
Who signed their name on the on the dotted line?

Start there-work out (or down)

No approval? Work down, one level at a time. Pull computer logs, phone calls, private email accounts, etc. Monitor all current communications. Revoke clearances. And so on & so on & so on until the perp is identified.
