My new favourite one being the US President is accused of leaking Isreali intel to the Russians. :D
In the 2000's which I'm more familiar with we called them the wire or AP, since they tended to burn every source within weeks via leaks to the press, their retired moles or through parliament.
Direct leaks from the US intelligence community are actually pretty darn rare, the only leaks that are not whistleblowers tend to be through the house and senate intelligence committees.
