江苏扬州一网民公共场合蹭网 卡里丢6万多存款(图)

2015-03-18 08:05:28   人民网

蹭网软件往往默认自动备份、分享热点,容易盗取个人隐私

现如今,公共场合的WiFi网络越来越多,饭店、商场、银行等等,手机上随时随地都能搜索到无线信号。有些无线信号需要密码,有些则不需要。这么多的无线网络,是不是我们都能随便连接呢?答案是否定的。央视记者昨天就做了一个实验,在公共场合用“蹭网软件”连上了一个需要密码的WiFi,当时用得很开心,不过回家之后央视记者发现,自己家里用的无线也泄露出去了。

还有更极端的例子,扬州一位市民就因为在公共场合蹭了个网,结果卡里6万多元不翼而飞了。

“蹭网神器”:你蹭别人,别人蹭你

蹭网软件存重大安全隐患,能盗取个人隐私

如果有一款手机软件声称可以帮您“蹭网”,走到哪儿都有免费WiFi,相信很多人都会乐意下载使用。不过,记者调查发现,这类“蹭网神器”存在重大安全隐患,想占便宜有可能被盗取个人隐私,究竟怎么回事呢?

记者进入手机应用商城,不费力气就找到了一款名为WiFi万能钥匙的蹭网软件,下载该软件后,记者试着搜索附近wifi热点,但是大部分都加密了。这时使用WiFi万能钥匙重新搜索,在不知道密码的情况下,记者的手机成功连接上其中一个WiFi。

安全技术专家方振宇告诉记者,在默认的情况下,这个WiFi密码就会被分享出去,任何人只要手机上面安装了WiFi万能钥匙这个软件,在这个WiFi信号覆盖范围内,就可以查询到这个WiFi密码,连上这个WiFi网络。

没想到软件这么方便,但是为什么会有涉密的危险呢?技术人员让记者回忆自己安装软件的步骤,记者突然想起来,很多设置都是默认勾选的,而这就是危险的开始。方振宇说,实际上在用户安装这个软件第一次打开的时候,在引导页就会自动勾选分享热点,还有自动备份,用户把这个密码分享出去,实际上他使用的过程中,并不能察觉到这个行为。

也就是说,首次进入时,记者已经选择同意将曾使用的WiFi密码分享到云端。回家后,记者只要连接自家的WiFi,密码立刻就被共享备份,公开出去了。记者免费蹭网的同时,也默默贡献了自己的WiFi,给更多人使用。

安全专家邓义乔解释说,当WiFi万能钥匙积累到越来越多的数据之后,给用户造成的连接WiFi的成功率会越来越高,这样的话有更多人去使用这个软件,实际上是为了软件推广的一种手段。

实验做到这里,记者也不清楚自己到底是占了便宜还是成了别人的便宜,不过,北京的尚小姐就更冤枉了,她根本就没有安装蹭网工具,自家的WiFi也被别人使用了。

尚小姐说:“之前网速一直都正常,前段时间突然发现,家里网速特别慢,发现我们家WiFi是有人蹭网的。我们家密码其实设置得就是比较难的,一般人都猜不到的。我只有把密码告诉过来我家做饭的阿姨,结果发现阿姨确实有装那个WiFi万能钥匙。”

也就是说,只要安装过蹭网工具的机主,使用任何一地的WiFi,就会自动把此地的WiFi密码分享,小尚属于无端躺枪。更令人担心的是,连接WiFi上后会产生很多安全风险,例如预谋者对连在网络内的手机、电脑等设备进行监控,植入木马和病毒,窃取银行、支付宝等密码。
