Smartphones are very popular because of their openness and scalability, but their shortcomings are not enough. Smartphones have become places where illegal merchants place malicious bombs; recently received feedback from several users that their phones were maliciously deducted. In fact, cases of malicious deductions are common. We seek the root cause. We cannot control illegal merchants. The final problem is that the user has low security awareness, does not pay attention to permission management, and will not use mobile phone security tools to protect security to the best extent and eliminate malicious deductions. Malicious deductions of Dark Night summarizes them into two types through his own experience. First, it is the deduction of SMS. Most of this deduction methods appear in stand-alone game apps, and you can deduct fees without prompting you to click; secondly, the backend networking wastes data traffic and causes excessive phone bills. Of course, there may be more advanced methods of deduction, but there are only two most commonly used in software apps. In response to this situation, An Ye will share with you two methods to eliminate malicious deductions.

[Security Center prohibits SMS and Internet connection functions]

For software or games that have been installed on the mobile phone, we can use the mobile phone's own or authoritative third-party permission management tools to prohibit SMS and Internet connection functions. I took the MIUI system's prohibited text message function as an example, and opened the Security Center → Authorization Management → Application Permission Management → Permission Management (This page has various permissions, operate as needed) → SMS and MMS → Send SMS → Select the software that needs to prohibit text message function as a rejection status or inquiry status. For privacy and security, it is recommended that APPs that you think are unsafe are prohibited, whether they are sending text messages, modifying text messages, reading text messages, sending MMS messages, or connecting to the Internet (in order not to offend APP manufacturers, all the APPs in the figure below have added mosaics).

[SMS and networking functions are prohibited during installation]

If you have installed, you can use authorization management to prohibit the relevant permissions. Then for the APP that is about to be installed, it will be simpler. For security, we must first install and download APPs in a regular APP market, such as the more authoritative app stores that come with your mobile phone (except bad mobile phone merchants) and AppTreasure. This is relatively safe. For the apps you are installing, as long as you install the APP, we should not rush to complete it. The SMS and Internet connection functions are prohibited in the installation interface. 90% of users click to complete or open it immediately after completing the installation, regardless of permissions at all. In fact, this step is very important (reply to the shot).

[Network control completely bid farewell to the background installation]

can selectively set most core permissions through permission management and installation permission selection, but some may think that if you simply control the Internet function to use permission management, it will be particularly troublesome. At this time, we need to use the network control function of the security center. Open Security Center → Network Assistant → Network Control → Disable the software from using wifi or traffic → Set default installation permissions. Through networking control, we can flexibly select application networking permissions and set network permissions for newly installed applications, which are free and secure.

In fact, you can use authorization management to control the permissions of the software. Basically, you will not encounter malicious deductions. Three key points of eliminating malicious deductions. First, try to download and install the software app in a safe and authoritative application market as much as possible; secondly, for installed software, supervise the permissions that the software may deduct through permission management and supervision, and root authorization should be cautious; finally, every time you install the software, try to set the permissions as much as possible, and strive to be the safest from the beginning. If the above three methods cannot make you feel safe, Dark Night can only use the ultimate move, unlocking/flight mode, which is the safest. Although this post only illustrates the operation methods of SMS and Internet access, the key point that An Ye wants to express is that everyone must pay attention to authorization management. Perhaps because of your attention, it can reduce property losses for you, and more importantly, protect the security of personal information.
