全面认识手机病毒时代
手机病毒正在慢慢地接近并渗透进我们的生活，然而，你对它又了解多少呢？你知道什么是手机病毒嘛？你知道手机病毒的危害有多大嘛？你知道如何去防范和清除手机病毒嘛？如果你对笔者的问题一问三不知的话，赶紧阅读本篇关于手机病毒的专题报道吧。
一、手机病毒的概念
手机病毒也是一种计算机程序，和其它计算机病毒（程序）一样具有传染性、破坏性。手机病毒可利用发送短信、彩信，电子邮件，浏览网站，下载铃声等方式进行传播。手机病毒可能会导致用户手机死机、关机、资料被删、向外发送垃圾邮件、拨打电话等，甚至还会损毁 SIM卡、芯片等硬件。
二、手机病毒的历史
历史上最早的手机病毒出现在 2000年，当时，手机公司Movistar收到大量由计算机发出的名为“Timofonica”的骚扰短信，该病毒通过西班牙电信公司“Telefonica”的移动系统向系统内的用户发送脏话等垃圾短信。事实上，该病毒最多只能被算作短信炸弹。真正意义上的手机病毒直到2004年6月才出现，那就是“Cabir”蠕虫病毒，这种病毒通过诺基亚60系列手机复制，然后不断寻找安装了蓝牙的手机。之后，手机病毒开始泛滥。
那么，后来出现的手机病毒又有哪些？它们都有什么危害呢？
三、手机病毒工作原理
手机中的软件，嵌入式操作系统（固化在芯片中的操作系统，一般由 JAVA、C++等语言编写），相当于一个小型的智能处理器，所以会遭受病毒攻击。而且，短信也不只是简单的文字，其中包括手机铃声、图片等信息，都需要手机中的操作系统进行解释，然后显示给手机用户，手机病毒就是靠软件系统的漏洞来入侵手机的。
手机病毒要传播和运行，必要条件是移动服务商要提供数据传输功能，而且手机需要支持 Java等高级程序写入功能。现在许多具备上网及下载等功能的手机都可能会被手机病毒入侵。
四、手机病毒的危害
1．导致用户信息被窃。
如今，越来越多的手机用户将个人信息存储在手机上了，如个人通讯录、个人信息、日程安排、各种网络帐号、银行账号和密码等。这些重要的资料，必然引来一些别有用心者的“垂涎”，他们会编写各种病毒入侵手机，窃取用户的重要信息。
2．传播非法信息。
现在，彩信大行其道，为各种色情、非法的图片、语音、电影开始地传播提供了便利。
3．破坏手机软硬件
手机病毒最常见的危害就是破坏手机软、硬件，导致手机无法正常工作。
4．造成通讯网络瘫痪
如果病毒感染手机后，强制手机不断地向所在通讯网络发送垃圾信息，这样势必导致通讯网络信息堵塞。这些垃圾信息最终会让局部的手机通讯网络瘫痪。
五、手机病毒的种类
手机病毒按病毒形式可以分为四大类：
1． 通过“无红传送”蓝牙设备传播的病毒“卡比尔”、“Lasco.A”。
小知识：
“卡比尔”（ Cabir）是一种网络蠕虫病毒，它可以感染运行“Symbian”操作系统的手机。手机中了该病毒后，使用蓝牙无线功能会对邻近的其它存在漏洞的手机进行扫描，在发现漏洞手机后，病毒就会复制自己并发送到该手机上。
Lasco.A病毒 与蠕虫病毒一样，通过蓝牙无线传播到其它手机上， 当用户点击病毒文件后，病毒随即被激活。
2． 针对移动通讯商的手机病毒“蚊子木马”。
小知识：
该病毒隐藏于手机游戏“打蚊子”的破解版中。虽然该病毒不会窃取或破坏用户资料，但是它会自动拨号，向所在地为英国的号码发送大量文本信息，结果导致用户的信息费剧增。
3． 针对手机BUG的病毒“移动黑客”。
小知识：
移动黑客（ Hack.mobile.smsdos）病毒通过带有病毒程序的短信传播，只要用户查看带有病毒的短信，手机即刻自动关闭。
4．利用短信或彩信进行攻击的“Mobile.SMSDOS”病毒，典型的例子就是出现的针对西门子手机的“Mobile.SMSDOS”病毒。
小知识：
“ Mobile.SMSDOS”病毒可以利用短信或彩信进行传播，造成手机内部程序出错，从而导致手机不能正常工作。
六、手机病毒的传播方式
1．利用蓝牙方式传播
2004年12月，“卡波尔”病毒在上海发现，该病毒会修改智能手机的系统设置，通过蓝牙自动搜索相邻的手机是否存在漏洞，并进行攻击。
2．感染PC上的手机可执行文件
2005年1月11日，“韦拉斯科”病毒被发现，该病毒感染电脑后，会搜索电脑硬盘上的SIS可执行文件并进行感染。
3．利用MMS多媒体信息服务方式来传播
2005年4月4日，一种新的手机病毒传播方式出现，通过MMS多媒体信息服务方式来传播。
4．利用手机的BUG攻击
这类病毒一般是在便携式信息设备的“ EPOC”上运行，如“EPOC-ALARM”、“EPOC-BANDINFO.A”、“EPOC-FAKE.A”、“EPOC-GHOST.A”、“EPOC-ALIGHT.A”等。
七、手机病毒的攻击对象
1．攻击为手机提供服务的互联网内容、工具、服务项目等。
2．攻击WAP服务器使WAP手机无法接收正常信息。
3．攻击和控制“网关”，向手机发送垃圾信息。
4．直接攻击手机本身，使手机无法提供服务。
八、手机病毒的预防
1．乱码短信、彩信，删。
乱码短信、彩信可能带有病毒，收到此类短信后立即删除，以免感染手机病毒。
2．不要接受陌生请求。
利用无线传送功能比如蓝牙、红外接收信息时，一定要选择安全可靠的传送对象，如果有陌生设备请求连接最好不要接受。因为前面说过，手机病毒会自动搜索无线范围内的设备进行病毒的传播。
3．保证下载的安全性。
现在网上有许多资源提供手机下载，然而很多病毒就隐藏在这些资源中，这就要求用户在使用手机下载各种资源的时候确保下载站点是否安全可靠，尽量避免去个人网站下载。
4．选择手机自带背景。
漂亮的背景图片与屏保固然让人赏心悦目，但图片中带有病毒就不爽了，所以用户最好使用手机自带的图片进行背景设置。
5．不要浏览危险网站。
比如一些黑客，色情网站，本身就是很危险的，其中隐匿着许多病毒与木马，用手机浏览此类网站是非常危险的。
九、手机病毒的清除
现在，清除手机病毒最好的方法就是删除带有病毒的短信。如果发现手机已经感染病毒，应立即关机，死机了，则可取下电池，然后将 SIM卡取出并插入另一型号的手机中（手机品牌最好不一样），将存于SIM卡中的可疑短信删除后，重新将卡插回原手机。如果仍然无法使用，则可以与手机服务商联系，通过无线网站对手机进行杀毒，或通过手机的IC接入口或红外传输接口进行杀毒。
十、手机病毒防杀软件
手机病毒的发展必然促进防杀手机防病毒软件的发展。目前市场上的手机病毒杀毒软件主要有 Symantec、光华、 趋势科技等 。
1．Symantec手机杀毒软件
Symantec（赛门铁克）已经为诺基亚旗下的Symbian操作系统智能手机开发出了专门的杀毒软件。

Comprehensive understanding of mobile phone virus era
Mobile phone virus is slowly approaching and penetrate into our lives, but how much do you know it? Do you know what is the mobile phone virus thing? Do you know how much damage the virus cell phone thing? Do you know how to prevent and remove mobile phone virus thing? If you answer any question on the words of the author, and quickly read this special report on mobile phone viruses it.
First, the concept of mobile phone viruses
Mobile phone virus is a computer program, and other computer viruses (programs) like the infectious and destructive. Mobile viruses can be used to send SMS, MMS, e-mail, surf the web, download ring tones, etc. to spread. Mobile phone viruses can cause users to crash, shut down, data is deleted, to send out junk mail, make phone calls, or even damaged SIM cards, chips and other hardware.
Second, the history of mobile phone viruses
The earliest history of mobile phone virus appeared in 2000, when a large number of mobile phone company Movistar received issued by a computer named "Timofonica" harassment text messages, the virus through the Spanish telecommunications company "Telefonica" mobile system to system users to send bad language and other spam messages. In fact, the virus can only be counted as SMS bomb. Real mobile phone virus until June 2004 only, that is the "Cabir" worm, the virus replication through the Nokia Series 60 phone, and then continue to look for installed a Bluetooth phone. , The phone began to spread of the virus.
Then, the subsequent emergence of the virus and which cell phone? They all have risks?
Third, the working principle of mobile phone viruses
Phone software, embedded operating system (fixed in the chip operating system, generally JAVA, C + + and other languages), the equivalent of a small intelligent processor, it will be subjected to virus attacks. And not just simple text messages, including ringtones, pictures and other information, we need the phone to explain the operating system and then displayed to the mobile phone users, mobile phone viruses that rely on software vulnerabilities to invade the phone.
Mobile phone viruses to spread and run the necessary conditions for the mobile service providers to provide data transmission capabilities, and advanced mobile phones such as the need to support Java applications to write the function. Now with the Internet and download a lot of functions such as mobile phones are likely to be infected by viruses.
Fourth, cell phone against viruses
1. Lead to user information stolen.
Today, more and more mobile phone users personal information stored on the phone, and such as personal contacts, personal information, schedule, a variety of network accounts, bank account numbers and passwords. These important data must attract some people with ulterior motives of the "coveted", they will prepare a variety of mobile phone viruses, steal important information.
2. Distribute illegal information.
Now, the MMS popular for all kinds of pornography, illegal pictures, audio, film provides a convenient starting to spread.
3. Damage the device hardware and software
Mobile phone virus is the most common hazard damage the device software and hardware, cause the phone not work properly.
4. Paralysis caused by communication network
If the virus infected mobile phone, mobile phones continue to force the communication network to which to send spam, this will inevitably lead to the information communication network congestion. The spam will eventually make a partial paralysis of mobile communication networks.
Fifth, the type of mobile phone viruses
Mobile phone viruses by the virus can be divided into four categories:
1. Through the "no red transmission" Bluetooth devices spread of the virus, "Kabir", "Lasco.A".
Tips:
"Kabir" (Cabir) is a network worm that can infect run the "Symbian" operating system for mobile phones. Phone of the virus, will use the Bluetooth wireless feature of other vulnerable neighboring scan cell phone, cell phone, after the discovery of vulnerability, the virus will replicate itself and send the phone.
Lasco.A as viruses and worms, spread to others via Bluetooth wireless phone, when the user clicks the virus file, the virus is activated immediately.
2. Mobile communications business for mobile phone virus "Trojan mosquitoes."
Tips:
The virus hides in the mobile game "fight mosquitoes," the cracked version. Although the virus does not steal or damage the user data, but it will automatically dial the number to the location for the British to send a large number of text messages, resulting in the user's information costs soar.
3. BUG viruses for mobile phones "mobile hacking."
Tips:
Mobile hacking (Hack.mobile.smsdos) virus is spread by text message with a virus spread, as long as the user to view messages with the virus, mobile phone instantly shut down automatically.
4. Using SMS or MMS to attack "Mobile.SMSDOS" virus, a typical example is the Siemens mobile phones for the emerging "Mobile.SMSDOS" virus.
Tips:
"Mobile.SMSDOS" using SMS or MMS virus can spread, causing internal phone system error, which cause the phone not work properly.
Six, the phone mode of transmission of the virus
1. To spread using Bluetooth
December 2004, "Kapoor" virus in Shanghai found that the virus will modify the system settings of smart phones, via Bluetooth mobile phone automatically searches for the existence of loopholes in the adjacent and attack.
2. PC infected executable files on the phone
January 11, 2005, "Velasco" virus is found, the virus infected computer, the computer will search for executable files on the hard disk of the SIS and the infection.
3. MMS Multimedia Messaging Service by way of communication
April 4, 2005, a new way of mobile phone virus appeared, by way of multimedia messaging service MMS to spread.
4. BUG attacks using mobile phone
Such viruses are generally in the portable information device "EPOC" on the run, such as "EPOC-ALARM", "EPOC-BANDINFO.A", "EPOC-FAKE.A", "EPOC-GHOST.A", "EPOC- ALIGHT.A "and so on.
VII, mobile phone viruses target
1. Attack for mobile phone services to Internet content, tools, services and so on.
2. WAP server, an attacker can not receive the normal message WAP phone.
3. Attack and control the "gateway" to the phone to send spam.
4. Directly attack the phone itself, the phone can not provide services.
VIII, Prevention of mobile phone viruses
1. Garbled SMS, MMS, delete.
Garbled SMS, MMS may carry the virus, removed immediately after receipt of such messages, cell phone viruses in order to avoid infection.
2. Do not accept a strange request.
Use of wireless transmission capabilities such as Bluetooth, infrared receiver information, be sure to choose a safe and reliable delivery object, if an unfamiliar device is best not to accept the connection request. As I said before, mobile phone viruses will automatically search for wireless devices within the transmission of the virus.
3. To ensure download security.
There are many resources now available online mobile phone download, but a lot of virus hidden in these resources, which requires users to download various resources in the use of mobile phones while ensuring the safety and reliable download site, to avoid personal website.
4. Select Phone comes with the background.
Nice background image and the screensaver is certainly fun to watch, but the picture on the accurate with the virus, so the user is best to use mobile phones to set the background image comes.
5. Do not visit dangerous websites.
For example, some hackers, pornography is in itself very dangerous, many of them hidden viruses and Trojan horses, using a mobile phone browsing such sites is very dangerous.
Nine, cell phone virus removal
Now, remove the phone the best way is to delete the virus with a virus message. If you find the phone has been infected with the virus, should be immediately shut down, crashed, you can remove the battery, then remove and insert another SIM card phone models (not the same as the best mobile phone brand), will be stored in SIM card, delete the suspicious messages , re-insert the card back to the original phone. If you still can not use, you can contact the phone service provider, through a wireless web of mobile phone virus, mobile phone IC or through the access port or infrared transmission interface for antivirus.
Ten, mobile anti-virus software to kill
Necessary to promote the development of mobile phone anti-virus mobile anti-virus software to kill the development. Phone on the market today are antivirus software virus Symantec, Guanghua, Trend Micro and so on.
