World Of Warcraft Girl

The Corrupted Blood plague so closely resembled the outbreak of real-world epidemics that scientists are currently looking at ways MMORPGs or other massively distributed systems can model human behavior during outbreaks. The reaction of players to the plague closely resembled previously hard-to-model aspects of human behavior that may allow researchers to more accurately predict how diseases and outbreaks spread amongst a population.
Security concerns
When players create World of Warcraft accounts, they are asked to choose a username and password. Afterward, whenever they play World of Warcraft, they are asked to supply the same username and password in full. This is also the case when using account management facilities online. This type of authentication is vulnerable to keystroke logging. While this is not unique to World of Warcraft and is common to many MMORPGs, the game has been directly targeted with trojans being specifically crafted to capture account login details. Attacks have been reported as early as May 2006, although they may extend as far back as July 30, 2005. The game does, however, allow players to save their account name to the program to allow the player to only have to type their password.
