" If so, protocol would be to let Malaysia know before public announcement. Any word on a press conference in KL?""
Our PM called the Malaysian PM before announcing in Parliament hat something was found.
"I suspect help from various undisclosed sources. There is an obvious need to keep details and capabilities undisclosed."
All the PM said was from Satellite imagery. I doubt much else will come out unless whose ever satellite it is says so.
Suggest wait until the AMSA news conference in 10 minutes, then speculate further if you wish.
