智能手机普及率的飙升，让这一平台也开始成为网络黑客攻击的主要目标之一。据McAfee调查显示，恶意软件对智能手机及其他网络移动设备的攻击行为，已从2009年的704起增加至2010年的967起，上升了46%。

尽管威胁移动设备的恶意软件数量与个人电脑相比仍相对较少，但从增长比率来看已呈现较为严峻的发展趋势。该调查指出，手机安全威胁的上升与智能手机、平板电脑的普及有着直接联系，随着越来越多的用户通过电脑、平板电脑、智能手机及网络电视等设备访问互联网，网络威胁的规模和水平也将不断升级。

游戏邦获悉，手机平台的普及与黑客攻击之间同样存在类似的关联。SymbOS/Zitmo.A是去年最受人关注的恶意软件之一，其攻击对象为塞班手机，而后者也正好是使用率最高的智能手机平台之一。

Adobe公司PDF、Flash等产品是滋生黑客网络攻击行为的温床，因为网络视频及其他类似服务的蓬勃发展，这类产品的足迹几乎遍布所有移动设备。

人们目前没有充分认识到到手机安全威胁状况，是移动网络攻击行为上升如此之快的主要原因之一。几乎所有人都知道应该在自己的个人电脑上安装杀毒软件，但手机用户们却没有这种意识。McAfee预测，如果手机安全威胁仍然按目前的趋势发展，手机安全也终将形成气候，催生出一个与目前个人电脑安全同样大的市场，每年的资金投入可能达到数十亿美元。

据游戏邦了解，该调查还有另一个令人惊讶的发现，即近期的垃圾邮件数量已有所下降。在2010年第四季度，垃圾邮件在电子邮件总通信量中占据80%，这是其自2009年第一季度以来的最低水平。不过，这一结果并不值得庆贺，因为垃圾邮件的减少仅仅是几个大型僵尸网站停摆的结果而已。垃圾邮件制造者们目前正向其他服务器转移阵地，因此，McAfee预计未来垃圾邮件遍天盖地的现象仍将卷土重来。（本文为游戏邦/gamerboom.com编译，转载请注明来源：游戏邦）

McAfee: Malware Attacks On Mobile Devices Growing Rapidly

With the tremendous rise in the popularity of smart phones, they have also become a prime target for cyber criminals. According to McAfee, the malware attacks on smart phones and other mobile devices connected to internet rose by 46 percent in 2010 to 967 threats, compared to 704 threats that McAfee registered on mobile devices in 2009.

Although the number of threats on mobile devices was relatively small compared to PCs, the rise in percentage terms is showing a clear trend. The rise in mobile security threats has direct correlation with the rise in adoption of smart phones and tablets. According to the report:

As more users access the Internet from an ever-expanding pool of devices — computer, tablet, smartphone or Internet TV — web-based threats will continue to grow in size and sophistication.

A similar correlation exists between the popularity of a mobile platform and the attacks against that platform. One of the most high-profile threats last year was SymbOS/Zitmo.A, a malware that attacked Symbian phones, which are one of the most widely used smart phones.

Adobe products such as PDF and Flash provided the most fertile ground to cyber criminals, as these products are almost omnipresent on all mobile devices thanks to the proliferation of web video and other such services.

One of the main reasons for such an astounding rise in attacks against mobile devices is that people are currently unaware of mobile security threats. Almost everyone knows that one has to install an anti-virus software on his PC, but this is not an accepted norm for mobile users. If the current trend in mobile security threats continues, McAfee expects that mobile security may eventually become as big a market as PC security currently is, which accounts for billions of dollars in investments each year.

A surprising find of the report was the fact that spam has seen a decline in recent times. According to McAfee, Spam accounted for 80 percent of all email traffic in the fourth quarter of 2010, which is its lowest level since the first quarter of 2009. However, there was no reason for rejoice, as the slow down in spam was only a result of several large botnets been taken down. Spammers are currently moving their bots to other servers, so spam activity is expected to rise in the future.（source:socialtimes）
