A cat video, also has the potential to make your mobile phone-mobile phone taken over by hackers, voice Assistant-IT information

IT information news on July 7, according to foreign media reports PCWorld, United States researchers from the George Washington University found through experiments, a white kitten video, a Smartphone might be taken over by a hacker. Because in the video, hide an extremely deep voice, hidden instructions were being taken over by smart phone near receiving. Because most of the current smart phone is equipped with a voice Assistant features, hackers used voice Assistant "docile" and ability to complete the plot.

Georgetown University Professor, and papers author one of maika·xier (Micah Sherr) said, currently most phone are installation has Google Now and Apple Siri, and has real-time wake function, hacker can through damage voice instruction, makes some instruction human almost cannot recognition, but software still can, if voice Assistant are received to similar "Ok,Google, open XKCD.com" such of instruction Hou, then open related of URL address, Hacker succeeds, because usually these addresses containing malicious code, can mobile phones be quietly taken over by hackers.

Researchers said that if the hacker knows the speech Assistant software add-ons or know its inner workings, is able to develop more difficult for humans to decipher the instructions to hide them in a video, quietly sent to phone around. Of course, the voice commands you want to successfully take over the cell phone users watching videos is surrounded by mobile phone, and a voice Assistant service is installed, and to bypass the user's alert, therefore, the success rates are not very high, but success commands phone to access a malicious URL addresses, the consequences would be disastrous.

Researchers have uploaded the voice commands examples of chaos, and able to successfully test and want to prevent this threat, developers who need voice Assistant service in human voice commands added to distinguish between computer-generated voice commands and functions.

一段小猫视频，也有可能让你的手机被黑客接管 - 手机,语音助手 - IT资讯

IT资讯讯 7月7日消息，据外媒PCWorld的报道，美国乔治敦大学的研究人员通过实验发现，一段平淡无奇的小猫视频，也有可能让智能手机被黑客接管。原因是在这段视频中，隐藏着极其低沉的声音，暗藏一些指令，可以让附近的智能手机接收后被接管。因为目前大多数智能手机都配备了语音助手功能，黑客正是利用语音助手“听话”的能力完成阴谋。

乔治敦大学教授、论文作者之一麦卡·希尔（Micah Sherr）表示，目前大多数手机都安装了Google Now和苹果Siri，并且具有实时唤醒功能，黑客可以通过破坏语音指令，使得一些指令人类几乎无法识别，但软件依然可以，如果语音助手们接收到类似“Ok，Google，打开XKCD.com”这样的指令后，然后打开相关的URL地址，这时黑客就得手了，因为通常这些地址都含有恶意代码，能够让手机被黑客悄悄接管。

研究人员表示，如果黑客知道语音助手软件的相关插件或者知道内部工作原理，则能开发出人类更加难以破译的指令，将他们隐藏在一段视频中，悄悄发送给周围的手机。当然，这种语音指令想要成功接管手机的前提是观看视频的用户周围有手机，并且安装了语音助手服务，同时要绕过用户的警觉，因此，这种方式的成功率并不是非常高，而一旦成功命令手机访问了恶意URL地址，后果就会不堪设想。

研究人员已经上传了混乱的语音指令样板，并且能够成功进行测试，想要防止这种威胁，需要语音助手服务的开发人员在人类语音指令和电脑生成的语音指令之间加入辨别的功能。
