FBI发布安卓安全警告

Philip Elmer-DeWitt 2012-10-18
FBI警告称,近期有大量恶意软件在攻击安卓系统的移动设备,尤其是其中两个恶意软件能够侵入用户的设备,窃取个人信息,甚至远程监控、控制设备。恶意软件的猖獗再次凸显了开源开发环境的风险。

    •“越狱”或“ROOT”可以用来解除设备生产商或手机运营商对设备的某些限制,它使用户可以自由决定安装哪些程序以及如何使用设备。不过,“越狱”或“ROOT”会带来重大的安全隐患,增加设备遭受攻击的风险。无论是一名用户、一个应用或一项服务,一旦它在操作系统中“不受限制”地运行,或在“系统层面”运行,都有可能将设备的控制权拱手让人。

    •不要让设备连接到陌生的无线网络。这些无线网络可能是一些恶意接入点,可能会获取你的设备向另一台合法服务器发送的信息。

    •如果你想把设备卖出去,或是以旧换新,切记要先清空设备(重设为出厂状态),避免泄露设备上的个人数据。

    •智能手机需要升级才能运行某些应用和固件。如果用户忽略了这一点,设备遭到攻击的风险就会加大。

    •不要点击或下载来源不明的链接或软件。

    •你在使用电脑时是怎样防范恶意程序的,在智能手机上就怎样做。

    •Jailbreak or rooting is used to remove certain restrictions imposed by the device manufacturer or cell phone carrier. This allows the user nearly unregulated control over what programs can be installed and how the device can be used. However, this procedure often involves exploiting significant security vulnerabilities and increases the attack surface of the device. Anytime a user, application or service runs in "unrestricted" or "system" level within an operation system, it allows any compromise to take full control of the device.

    •Do not allow your device to connect to unknown wireless networks. These networks could be rogue access points that capture information passed between your device and a legitimate server.

    •If you decide to sell your device or trade it in, make sure you wipe the device (reset it to factory default) to avoid leaving personal data on the device.

    •Smartphones require updates to run applications and firmware. If users neglect this it increases the risk of having their device hacked or compromised.

    •Avoid clicking on or otherwise downloading software or links from unknown sources.

    •Use the same precautions on your mobile phone as you would on your computer when using the Internet.
