Casinos are essentially massive, highly fortified vaults containing millions of dollars in untraceable cash, making them the ultimate, irresistible target for ambitious criminals.

Some thieves used brute force, others used brilliant hacking skills, but all of them attempted to defeat the absolute most heavily guarded fortresses in the world.
The Stardust Heist: The Inside Job
Perhaps the most legendary, baffling, and purely simple casino heist in Las Vegas history occurred in 1992 at the famous Stardust casino.

Because he was a trusted, long-term employee, security completely ignored him as he casually strolled past the cameras and out into the blazing Nevada sun.

In 2013, an international syndicate successfully hacked into the casino’s highly secure, internal pan-tilt-zoom (PTZ) VIP surveillance camera network.

The casino eventually realized the statistical impossibility of the wins, uncovered the hack, and fired their top VIP manager, though recovering the funds proved incredibly legally complex.
Stealing $1.5 Million in Chips
In less than three minutes, he scooped up $1.5 million worth of massive $25,000 denomination “cranberry” chips into a duffel bag and fled on a parked motorcycle.

The Bellagio simply deactivated the RFID trackers embedded inside those specific $25,000 chips, rendering his massive $1.5 million haul completely worthless plastic.
