[LINK] Cyber hijack of MH370?

[Jim Birch]

IANAATC but as I understand it the plane did it's u-turn as it exited
Malaysian airspace and before it reached Vietnamese space.  It wasn't in a
direct handover.

Unlike military systems, civilian air traffic control systems work by
cooperation. Hopefully they pick up errors.  They are not designed to
handle planes that are positively trying to avoid detection.   With a lot
of planes in the air that are more deserving of your limited attention you
probably don't worry greatly about a missing signal on a plane that is
leaving your space with no problems reported.  Just guessing.  In a perfect
world this erratic behaviour might have been picked up.
