" e! j, ]: q1 h+ A同无线攻击一样,蓝牙攻击也按照原理分为多种方式BlueBug、BlueDump attack、BlueSnarf等,涵盖了蓝牙扫描、模块漏洞利用、暴力破解、交互数据嗅探等多个方面,我们就分别来看一看其具体实现。. x* @' ]' U& E! \5 U& s

随着带有蓝牙功能的智能手机及蓝牙适配器价格的下降,促使了更多的人开始接触蓝牙技术,尤其是在蓝牙耳机等附加设备的推动下,使得开启了蓝牙功能的智能手机、PDA等比比皆是。去年我去赛格电脑城给找配件,随手打开笔记本,使用笔记本自带的蓝牙模块就可以轻易地发现周围如此多的蓝牙设备,如下图,其中大部分是智能手机。至于机场、大型宾馆、会馆等人口稠密区域,开启蓝牙的设备更是数不胜数。
