Slammer (also known as Sapphire, Helkern or SQLExp) was a worm that appeared in 2003 January and was the fastest-spreading worm of its time. The worm was an extremely simple piece of code and its payload was an unintended byproduct of its spreading ability.
This remarkable accomplishment is driven by an approach called SLAM technology. SLAM: Simultaneous Localization and Mapping. SLAM technology stands for simultaneous localization and mapping, a process whereby a robot or a device can create a map of its surroundings, and orient itself properly within this map in real time. This is no easy task, and it currently exists at the frontiers of technology research and design.
