【步云分享】密码危机的启示 PS：我的密码已经泄露，还好是旧版的，我三个月前的版本，可见每三个月换一次密码还是有必要的
高步云 William Gao
有网友爆料称，今天有黑客在网上公开了知名网站CSDN的用户数据库，这是一次严重的暴库泄密事件，涉及到的账户总量高达600万个，我们部分同事确实也在泄漏的库里发现了自己的帐号。又到了修改密码的时候了: 
---------------------------------------------------------------------------------
CSDN这次数据泄漏，同时也给了我们一些有趣的分析数据。
我们可以轻松地统计挨踢人士的邮箱使用情况，以及通常的密码长度等信息：
大家通常最关心密码
来看看大家最经常使用的密码是什么吧
大家最使用的密码长度不如所料，是8位左右
csdn不限制密码长度的吗？（不像挨踢网站的风格啊）
身为一个IT人士或爱好者，大家的安全意思还是挺强的，密码最常见的是在8位到14位之间，一般来说是很安全的，当然不排除某些网站使用明文-_-#
最后一个有趣的数据是国内的邮箱使用情况
排在第一的竟然是qq.com
是大家出于无所谓呢，还是临时用一下的？不过不可否认，这几年qq邮箱做得还可以。

今天有黑客在网上公开了知名网站CSDN的用户数据库，这是一次严重的暴库泄密事件，涉及到的账户总量高达600万个。有人写了一个小程序，统计了这次公布的
6428632 个 CSDN
哪些密码出镜率较高？统计结果显示有239万人的密码和别人存在重复，在所有密码中，123456789出镜率高居榜首，有23万5千人使用它作为密码。
