So what happened to the mobile virus later? What harm do they have?

Third, the mobile phone virus working principle

Mobile phone software, embedded operating system (curing in the chip operating system, generally by JAVA, C + + and other languages), the equivalent of a small intelligent processor, so will be subject to virus attacks. Moreover, the text is not just a simple text, including mobile phone ringtones, pictures and other information, all need the operating system in the phone to explain, and then display to mobile phone users, mobile virus is relying on software system vulnerabilities to invade mobile phones.

Mobile phone virus to spread and run, the necessary condition is that mobile service providers to provide data transmission function, and the mobile phone needs to support Java and other advanced program write function. Now many mobile phones with internet access and downloads are likely to be hacked by mobile phone viruses.

1. Virus "Kabir", "LASCO.A" transmitted through "no red transfer" Bluetooth devices.

Small knowledge:

"Kabir" (Cabir) is a network worm that infects handsets running the Symbian operating system. After the virus in the phone, the use of Bluetooth wireless features in the vicinity of other vulnerable mobile phones scanned, after the discovery of the vulnerability of mobile phones, the virus will replicate itself and sent to the phone.

LASCO.A viruses, like worms, are transmitted via Bluetooth wirelessly to other phones, and the virus is activated when a user clicks on a virus file.

4. Using SMS or MMS to attack the "Mobile.smsdos" virus, a typical example is the emergence of a Siemens mobile phone "Mobile.smsdos" virus.

Small knowledge:

"Mobile.smsdos" virus can use SMS or MMS transmission, resulting in phone internal program error, resulting in mobile phone can not work properly.
