坐地铁无聊的时候，你是不是曾经打开手机蓝牙，搜索身边其他蓝牙用户，然后找个目标小小骚扰一下？严肃点跟你说，这可算是hijack（劫持）哦！

Bluejacking means temporarily hijacking another person's cell phone by sending it an anonymous text message using the Bluetooth wireless networking system. Bluetooth works over a range of about 10 metres and phones fitted with it can be made to search for other handsets using it that will accept messages sent to them.

Bluejacking（bluetooth＋hijacking，蓝牙劫持）指通过蓝牙无线传输网络给别人的手机发送匿名信息，感觉就好像突然把人家的手机劫持了一样。蓝牙的有效传输距离为十米，也就是说，在十米范围内可以搜索到其它正在使用蓝牙功能的便携设备，并向其发送信息。

Bluejacking is usually harmless, but because bluejacked people generally don't know what has happened, they may think that their phone is malfunctioning. Usually, a bluejacker will only send a text message, but with modern phones it's possible to send images or sounds as well. Bluejacking has been used in guerrilla marketing campaigns to promote advergames.

蓝牙劫持一般都不是恶意的。不过，因为收到匿名信息的人通常都不知道是怎么回事，所以有时会认为是他们的手机出了问题。蓝牙劫持者一般会发送文字信息，不过，随着手机不断更新换代，现在也可以传送图片和音频文件了。蓝牙劫持多用于宣传广告游戏的游击营销活动。
