New iPhone Trojan Spreading

US-CERT has received reports of a new Trojan horse program that affects the Apple iPhone. This Trojan claims to be a tool used to prepare the device for an upgrade to firmware version 1.1.3. When a user installs the Trojan, other application components are altered. If the Trojan is uninstalled, the affected applications may also be removed.

US-CERT strongly encourages users to install updates and application software only from trusted sources.
