What was the most hi-tech heist in history???

What were the details and who were the robbers? Did the thieves get away with it?

I’ve read about the exploits of a gang of thieves in Europe nicknamed “the Dream Team” (taking this name from the Barcelona Soccer Club). These people seemed to commit some pretty slick robberies (involving electrical bombs and machine gun equipment brought from the Balkans), raiding security vans and various banks across France and Spain.

But has there ever been a super slick, hi-tech robbery/heist? Is there any score that has come to be known as the most technically advanced ever? What about from the ones you’ve heard of?
