Trojan intrusion into Microsoft's smartphone system to modify Security Settings

My mobile phone virus is not infected yet, that is, it is easy to crash.

Researchers found that handheld devices using the Microsoft Windows Mobile operating system may be compromised by a Trojan.

This kind of trojan named WinCE/InfoJack will install illegal files in the smartphone, steal user information, and open the door for further virus infection.

McAfee researcher Jimmy Shah disclosed in the company's blog that this trojan changed the mobile phone security settings to the lowest level and left a backdoor for other viruses, these viruses are installed on mobile phones without any warning.

The US Computer Emergency Response Team (US-Cert) noticed that this Trojan can also prevent itself from being deleted and change the user's browser homepage.

This trojan is hidden in many valid download files. The modified Homepage contains infected programs including Google Maps, many games, and stock trading software.

Shah said that the trojan was originated from a website in China, which has now been closed. He added that when receiving the question, the administrator of the website explained that the software was only used to count the mobile phone models used to access their website.

Shah believes that it is obvious that they did not notify users before installing the software, and they did not provide a method to uninstall the software after installing it.

US-Cert encourages users to install anti-virus software and keep them updated. In addition, they should be especially careful when installing programs on their mobile phones.
