Mobile phone viruses are slowly approaching and infiltrating into our lives. However, how much do you know about it? Do you know what a mobile phone virus is? Do you know how harmful mobile phone viruses are? Do you know how to prevent and remove cell phone viruses? If you don’t understand the author’s questions, please read this special report on mobile phone viruses. 1. The concept of mobile phone virus Mobile phone virus is also a kind of computer program, which is as contagious and destructive as other computer viruses (programs). Mobile phone viruses can be spread by sending text messages, MMS, emails, browsing websites, downloading ringtones, etc. Mobile phone viruses may cause users' mobile phones to freeze, shut down, delete data, send spam emails, make phone calls, etc., and even damage SIM cards, chips and other hardware. 2. The History of Mobile Phone Viruses The earliest mobile phone virus in history appeared in 2000. At that time, the mobile phone company Movistar received a large number of harassing text messages named "Timofonica" sent by computers. The virus passed through the mobile system of the Spanish telecommunications company "Telefonica" Send spam text messages such as swear words to users in the system. In fact, the virus can only be considered a text message bomb at best. The real mobile phone virus did not appear until June 2004, and that was the "Cabir" worm. This virus replicated through Nokia 60 series mobile phones, and then continued to look for mobile phones with Bluetooth installed. After that, mobile phone viruses began to spread. So, what are the mobile phone viruses that appeared later? What harm do they have? 3. Working principle of mobile phone viruses: The software in mobile phones and the embedded operating system (operating system solidified in the chip, usually written in languages ????such as JAVA and C++) are equivalent to a small intelligent processor, so they will be attacked by viruses. Moreover, text messages are not just simple text. They include ringtones, pictures and other information, which need to be interpreted by the operating system of the mobile phone and then displayed to the mobile phone user. Mobile phone viruses rely on vulnerabilities in the software system to invade the mobile phone. For mobile phone viruses to spread and run, the necessary conditions are that the mobile service provider must provide data transmission functions, and the mobile phone must support advanced program writing functions such as Java. Nowadays, many mobile phones with functions such as Internet access and downloading may be invaded by mobile phone viruses. 4. The dangers of mobile phone viruses 1. Leading to user information being stolen. Nowadays, more and more mobile phone users store personal information on their mobile phones, such as personal address books, personal information, schedules, various network accounts, bank account numbers and passwords, etc. These important information will inevitably attract the "covet" of some people with ulterior motives. They will write various viruses to invade mobile phones and steal users' important information. 2． Spread illegal information. Nowadays, MMS is very popular, which facilitates the spread of all kinds of pornographic and illegal pictures, voices and movies. 3. Destroy mobile phone software and hardware The most common harm caused by mobile phone viruses is to damage mobile phone software and hardware, causing the phone to fail to work properly. 4. Causes communication network paralysis. If a virus infects a mobile phone and forces the mobile phone to continuously send spam messages to the communication network where it is located, this will inevitably lead to information congestion in the communication network. These spam messages will eventually paralyze local mobile phone communication networks. 5. Types of mobile phone viruses Mobile phone viruses can be divided into four major categories according to virus forms: 1. Viruses "Kabir" and "Lasco.A" spread through "red-free transmission" Bluetooth devices. Quick Facts: Cabir is a network worm that infects mobile phones running the Symbian operating system. After the mobile phone is infected with the virus, it will use the Bluetooth wireless function to scan other nearby vulnerable mobile phones. After discovering the vulnerable mobile phone, the virus will copy itself and send it to the mobile phone. The Lasco.A virus, like the worm virus, spreads wirelessly to other mobile phones through Bluetooth. When the user clicks on the virus file, the virus is immediately activated. 2． The mobile phone virus "Mosquito Trojan" targets mobile carriers. Quick Facts: The virus is hidden in the cracked version of the mobile game "Kill the Mosquito". Although the virus will not steal or destroy user data, it will automatically dial and send a large number of text messages to numbers located in the United Kingdom. As a result, the user's message bill will increase dramatically. 3. Virus "mobile hacker" targeting mobile phone bugs.

Tips: The mobile hacker (Hack.mobile.smsdos) virus spreads through text messages containing virus programs. As long as the user views the text messages containing the virus, the phone will automatically shut down immediately. 4. A typical example of the "Mobile.SMSDOS" virus that uses text messages or multimedia messages to attack is the "Mobile.SMSDOS" virus that targets Siemens mobile phones. Tips: The "Mobile.SMSDOS" virus can spread using text messages or multimedia messages, causing errors in the internal program of the phone, causing the phone to not work properly.
