What kind of text messages will be intercepted by mobile phones?

General advertising text messages, as well as various promotional text messages.

Nowadays, mobile phones intelligently intercept text messages. Some numbers that are not on the blacklist are marked as harassing phone numbers and are intercepted. The main thing is to obtain advanced permissions of the system. After receiving the text message, first check the content of the phone number and message content keywords. If any blacklisted or spam words are found, filter them out.

So it is also possible to kill by mistake. For example, if a friend’s text message happens to mention the keywords you have blocked, the mobile phone system will automatically filter and intercept them for you.

Introduction and methods of mobile phone SMS interception

With the widespread popularity of smartphones and the increase in mobile network bandwidth, the interaction between terminals and operators, and between terminals, has gradually increased; According to data provided by global anti-virus agencies, by 2009, there were more than 300 viruses that infected terminals through mobile phone harassment, and the growth trend was even faster.

Considering that mobile phones are closer to users’ lives than computers, and the information stored is also more important, mobile phone harassment interception is still necessary.

Mobile phone harassment interception technology obviously lags behind computer harassment interception technology. However, ensuring the security of mobile phones is far more important than ensuring the security of computers. Mobile phones are affected by the characteristics of their hardware configuration and operating system design ideas. Restrictions such as these make it unsuitable to run medium and large software designed for computers on mobile phones, especially when the full version of anti-virus software is unable to perform anti-virus operations.

It is unrealistic to expect that the slimmed-down mobile versions of these computer anti-virus software can protect users’ mobile phone security. Computer anti-virus software is so fat that virus checking is time-consuming and labor-intensive. The inefficient performance, the annoying and constant asking mechanism that users don’t know how to deal with, seems so unusual when used on mobile phones.

So, mobile phone anti-virus obviously cannot simply apply the computer anti-virus model and apply computer anti-virus ideas to the design of mobile phone anti-virus software. Instead, a new anti-virus concept is needed to ensure the safety of mobile phone users.
