屏幕指纹解锁手机现最大漏洞,任何人都能解锁,供应商要背锅
现如今,我们所使用的手机是越来越智能化,从最早的传呼机到功能机时代,再到现在的智能机时代,而且还在不断的进步。
单从手机解锁来说从最早的密码解锁到后置指纹解锁或者是前置指纹解锁,发展到人脸解锁,到现在都有了屏幕指纹解锁了。
而且屏幕指纹解锁也都成为了先进的代名词,能够为我们带来更好的使用体验,各大手机厂商都在制作。
屏幕指纹解锁手机现最大漏洞,任何人都能解锁,供应商要背锅。
不过,在前几天的GeekPwn2018大会上,有技术团队却发现了屏幕指纹解锁功能存在非常严重的安全漏洞。
就是只要是具有屏幕指纹解锁功能的手机,只用一张白色卡片就能很轻易的实现解锁,而且难度低到任何人都能使用。
不过就是有个前提条件,那就是手机必须是机主刚录过指纹或者是刚用指纹解锁过。公布该漏洞的技术团队还在现场演示了一番。
工作人员将白色卡片贴在指纹区域,用手指按压,神奇的一幕就出现了,手机竟然识别出机主的指纹并且进入桌面。
而后现场主持人也是试验了一番,同样的,也是很轻易的就解锁了手机,甚至是评委上去都很轻易的解锁了手机。
这个问题还是非常严重的,如果说在支付环境下解锁了,那造成的损失将无法估计,随后该技术团队表示,这并不是某个手机品牌的问题。
而是手机零件供应商的问题,如果说真是这样的话,那估计任何有屏幕指纹解锁功能的手机都会无法避免的中招啊!
道理很简单,当我们使用过指纹之后,屏幕上难免就会留下痕迹,再说现阶段屏幕指纹是基于光学检测的技术。
而并非是超声波技术,这样的话,当指纹识别模块进行指纹检测的时候,就会检测到这个残迹,手机自然也就解锁了。
这个漏洞也就被命名为“残迹重用”漏洞,不过技术团队表示,目前已经和屏幕指纹供应商沟通过,修复了此漏洞。
不过还是要提醒广大的手机用户,在使用手机时,还是要谨慎小心为妙!
