Threat Primer: Worms
A worm is a self-propagating code execution attack that causes damage on each host that it infects. In less technical terms, a worm is a virus that causes damage, then finds another host to propagate to. This process repeats until it is stopped in its tracks by some effective mitigation, or until it cannot find any additional hosts to transfer to. Here are the key steps that attackers use to implement this type of attack.
