In reflection, can also steal passwords-WiFi WiFi signal, the password-IT information

IT information news on August 29, about how hackers to steal passwords by an attacker, the most common method is through a Trojan or other virus secretly to steal, or by the method of collision to try and crack. And now, reports that hackers can steal passwords through WiFi signal, have you ever been scared.

According to foreign media reports, recently, the United States State of Michigan State University and researcher at the University of Nanjing, China announced, they can be used with a normal router WiFi signal detection to be the attacker's keystrokes record, to obtain a user's password.

According to reports, researchers using a MIMO Router (multiple-input-multiple-output) functions by collecting small changes in WiFi signals, they can even create a map of the indoor environment.

When the user entered the notebook operation, researchers can grab the users hands, fingers and the keyboard WiFi signal interference caused by small changes in the data, so as to obtain relevant such as keystroke logging and password information, accuracy of 77% and 97.5%.

Even more frightening is, through this technology, WiFi signal even for reading user gestures, lip movements, and so on. However, when there are two or more laptop room, this target could not be determined.

细思极恐，WiFi信号也能盗取密码 - WiFi,密码 - IT资讯

IT资讯讯 8月29日消息，关于黑客如何盗取被攻击者密码，最常见方法就是通过木马或者其他病毒暗中窃取，亦或者通过撞库的方法尝试破解。而现在，有报道称，黑客通过WiFi信号就能盗取密码，你有没有被吓到。

据外媒报道，近日，美国密歇根州立大学和中国南京大学的研究人员宣布，他们可通过一个普通路由器使用WiFi信号准确检测到被攻击者的击键记录，从而获得用户密码。

据介绍，研究人员主要利用了路由器的MIMO（多输入多输出）功能，通过收集WiFi信号的微小变化，他们甚至可以创建一张室内环境地图。

当用户对笔记本进行输入操作时，研究人员就能抓取由用户双手、手指以及键盘微小变化引起的WiFi信号干扰数据，从而获得相关的击键记录和密码等信息，准确率达到77%到97.5%之间。

更令人恐怖的是，通过该技术，WiFi信号甚至还能用于读取用户手势、嘴唇动作等。不过，如果房间内存在两台甚至更多笔记本时，这种方法就无法确定攻击目标了。
