If a Facebook friend contacts you about a free money program by the UN called “UNDEF Program”, don’t fall for it.
FIRST: Search your friends list, you will find that the person contacting you has cloned your real friend’s Facebook profile, and is impersonating them.
Your friend’s Facebook profile has been hacked.
You should immediately contact your friend, other than through Facebook, and warn of the breach.
You should also report the profile to Facebook Security.
