Category Archives: Opportunists

Use Cases related to the opportunist attacker class. This class includes but is not limited to Bots, Worms, Mass Malware, Script Kiddies. They are opportunistic in the way that they move on if they don’t find a particular known vulnerability. The sophistication is relatively low and to compensate for it they use large scale.
