In fact, mobile phone viruses are the same as computer viruses. They can send messages to mobile phones through computers.
Strictly speaking, the mobile phone virus should be a computer virus, which can only spread on computer networks rather than through mobile phones, therefore, the so-called mobile phone virus is actually a computer virus program that starts a service of a telecommunications company, such as the function of sending an email to a mobile phone Short message, and it sends a document to a mobile phone, there is no destructive power at all.
Of course, some mobile phone viruses are still quite destructive. Once an attack may be worse than a personal computer virus, the transmission speed may be faster than the virus "I love you.
In addition, short messages, WAP services, and other commands that can be written into the system or memory, the attacker only needs to find the gap and send a virus-infected short message, and use Assembly Programming to change the machine code of the system ), the command is hidden in the memory, and then the phone book of other mobile phones is turned on to spread viruses and attack the boot system of the mobile phone within a certain period of time.
Attack methods
Many mobile phone users worry that WAP phones will become an important target of hacker attacks. It is easier to directly attack WAP mobile phones over the network than to attack GSM mobile phones. In this regard, some experts once pointed out that this technology is very difficult. In addition, most mobile network operators have already set up security systems on WAP servers and "gateways", so generally users do not have to worry about it.
Representation
First, the WAP Server is attacked to make the WAP mobile phone unable to accept normal information.
Second, attack and control the "Gateway" and send spam information to the mobile phone.
Third, they directly attack the mobile phone itself, making the mobile phone unable to provide services. (This type of destruction is relatively difficult and is difficult to achieve at the current technical level)
Measures Taken
1. Close the phone with garbled characters
Ii. Download as little information as possible from the Internet
3. Pay attention to possible viruses in Short Messages
4. Scan and kill viruses on mobile phones.
At present, there are two main technical measures to deal with mobile phone viruses: first, anti-virus for mobile phones through wireless websites; second, anti-virus through Mobile Phone IC access ports or infrared transmission ports. Most mobile phone viruses do not damage the mobile phone hardware in a short period of time. Therefore, users do not need to be alarmed after receiving a text message with a virus, as long as they delete the virus.
