Backdoor.Jupdate

Backdoor.Jupdate is a backdoor program that allows a remote attacker to download and execute files on an infected machine.



There is evidence which indicates that Backdoor.Jupdate is installed in the same method as Trojan.Vundo. A computer may get infected when the user visits a web page which exploits the Microsoft Internet Explorer Malformed IFRAME Remote Buffer Overflow Vulnerability (as described in Microsoft Security Bulletin MS04-040).
