Hi, The case with MySpace is not the first one when for a special environment, such as social networking there is created self-propagating code. In August this year in Latvian Internet there appeared a conceptual code which was able to send himself to users of the site Draugiem.lv (analoque of MySpace.com). Draugiem.lv has its own internal messaging system. By the way of exploiting XSS vulnerability conceptual code (JavaScript) was able to send himself to other friends when user only looked at the infected message. The code is added to Kaspersky Anti-Virus database as Worm.JS.Graud.a. Best regards, Valdis----- Original Message ----- From: "Xavier" <compromise () gmail com>
