应对来路不明的U盘要加一万个小心都不为过,要知道有很多U盘都不能轻易插入自己的电脑,否则后患无穷,而且远不止在你电脑上植入恶意软件这么简单。

下面这款可是立竿见影的实体破坏式U盘,它有一个令人闻风丧胆的名字“夺命U盘(USB Killer)”。 如果你不慎插入,你就需要为你的电脑设备和里面的重要资料默哀了,因为它能够以高压电脉冲摧毁插入它后的各种个人电脑和笔记本以及里面的部件,尤其是脆弱的硬盘。

这个邪恶的设备首先来源于俄罗斯网站Habrahahbr,后来经Kukuruku Hub网站传入美国。据Kukuruku Hub页面介绍,这款夺命U盘的破坏原理很简单,插入USB端口后,内置的DC/DC直流斩波器会开始运作,将电压提升至110V,随后直流斩波器关闭,场控晶体管开启,将110V高电压加载至USB总线的讯号通路中,当电容器电压增至7V时,晶体管关闭直流斩波器继续运行。

如此循环直到破坏各个能够破坏的电子元器件。这个设备告诉我们千万不要尝试随便插入来历不明的U盘,但是我们可以推测对于特工们来说这货绝对是是销毁机密文件的利器。
