Apple's mobile phone shows all the information of this machine to others. Is it dangerous?

This situation may be dangerous, so we must pay attention to the information security of mobile phones. Let me give you some advice.

1. Address books, passwords, text messages, phone calls and photos may all be stolen.

2. Personal information on the mobile phone includes location information, communication information, account password information and stored file information. Among them, communication information includes address book, call record, short message, etc. The file information stored in the mobile phone includes photos, recordings, videos and other files. In addition, some hardware information of mobile phone, such as INEI number, Mac address of wireless network card, hardware configuration information, etc., also belong to the category of personal information.

Experts warn that "infringing on the personal information security of mobile phones" is not only stealing users' address books, text messages and photos. At present, some applications secretly collect users' location information, mobile phone online records and other information, which seems unremarkable, but in fact, analyzing users' habits based on these information has great commercial value and may also become the target of infringement. Moreover, this kind of infringement is relatively hidden and should not be detected.
