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.
SLAM technology typically overcomes this complex chicken-and-egg issue by building a pre-existing map of an environment using GPS data. This map is then iteratively refined as the robot or device moves through the environment. The true challenge of this technology is one of accuracy.
