坐地鐵無聊的時(shí)候，你是不是曾經(jīng)打開手機(jī)藍(lán)牙，搜索身邊其他藍(lán)牙用戶，然后找個(gè)目標(biāo)小小騷擾一下？嚴(yán)肅點(diǎn)跟你說，這可算是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，藍(lán)牙劫持）指通過藍(lán)牙無線傳輸網(wǎng)絡(luò)給別人的手機(jī)發(fā)送匿名信息，感覺就好像突然把人家的手機(jī)劫持了一樣。藍(lán)牙的有效傳輸距離為十米，也就是說，在十米范圍內(nèi)可以搜索到其它正在使用藍(lán)牙功能的便攜設(shè)備，并向其發(fā)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.
藍(lán)牙劫持一般都不是惡意的。不過，因?yàn)槭盏侥涿畔⒌娜送ǔ６疾恢朗窃趺椿厥?，所以有時(shí)會(huì)認(rèn)為是他們的手機(jī)出了問題。藍(lán)牙劫持者一般會(huì)發(fā)送文字信息，不過，隨著手機(jī)不斷更新?lián)Q代，現(xiàn)在也可以傳送圖片和音頻文件了。藍(lán)牙劫持多用于宣傳廣告游戲的游擊營銷活動(dòng)。
