Common mobile phone security vulnerabilities and Solutions

 

A. System Software Vulnerabilities

 

Like computer system vulnerabilities, mobile phone system software often exposes system vulnerabilities, and security problems are common due to system software vulnerabilities. Apple has been exposed by hackers, and software vulnerabilities may be remotely manipulated by devices such as iPhone, iPad, and iPod Touch.

 

Solution:

 

1. Get the Root directory permission, often referred to as "Root device", to delete the system software that causes the disease.

 

2. Wait for the official release of vulnerability patches, or refresh more sophisticated systems.

 

B. Application Vulnerabilities

 

Applications downloaded from smart phones have vulnerabilities, which are common bugs. Currently, there are a lot of banking software in Apple's iPhone APP Store. Previous reports showed that Citibank's mobile banking software for Apple's iPhone had vulnerabilities in collecting sensitive user data and storing it in hidden documents on mobile phones, when a mobile phone is connected to a computer, banking software may store some account information on the PC, which may cause information leakage. Citibank said it had fixed the vulnerability.

 

Solution:

 

1. Wait for the software provider to fix the BUG and provide the updated software. When updating software in the APP Store, you will often see the update prompt "fixed some bugs", which means to fix vulnerabilities that may be caused by the software.

 

2. The software cannot be updated. You can delete the software directly when you confirm that there is a problem with the software. However, sometimes software deletion may occur, and some related information may also be deleted.

 

C. Download insecure programs

 

According to yiguan International's 2011 mobile phone security report, 81.8% of users indicated that installing software with unknown experience was the most important way to infect mobile phones with viruses. Therefore, installing insecure software from unknown sources may also cause mobile phone security vulnerabilities. With the continuous popularization of low-end smart phones, the installation of software with unknown experience resulting from strong binding and downloading, receiving text messages with links, and sending and downloading of MMs have become the main cause of infection.

 

Among the security consequences caused by this, mobile phone charges are still at the top of the list. In addition, it will also lead to abnormal increases in traffic and abnormal increases in phone bills. At the same time, some specific information may also lead to leaks.

 

Solution:

 

1. Do not download software from unknown sources, especially links to text messages or MMS; do not click to download and install the software;

 

2. install security software such as regular brand security guard and Mobile Phone Manager to improve system settings and avoid downloading and installing insecure programs.
