Hacker IP log

221.236.12.33  四川省成都市 电信

这位hacker用中国人常用的login 和 password作测试。但是由于我的passwords,正常需要最长300年才能测试出来,所以很多hackers,一般攻击不久就离开。所以我再打算把密码加长两位,加上大小写英文字母,最长需要7千万年才解开。估计用美国的超级电脑也需要这个时间,那么一般的hackers也有那么多的时间呢?

这位hacker用了15分钟去攻击我的Asterisk Server。之前有一位克罗地亚的hacker花2个小时。

    用咩命令  在边处可以睇到这个信息?

Another one trying to break into my non-existing ftp server for the third time today. Poor hacker

It tries to login one time per second. For 12 digit password with alphabets and numbers, i.e., the hacker needs (26X2+10)^12/(60X60X24X365)=102,304,247,919,771 years. Good luck!

    it also depends how the hacker uses. Some times, they have a robot to generate password within a very short time. However, if it is from a causal person, the trial and error will be much slower and a few attempt.

Even though hackers use robot (machine) to generate a password patterns, the frequently of password hacking will not be very high. As a result, for a 10-16 digit long password should be good enough to reduce the chances of being hacked.

不知道是否我加了alwaysauthreject=yes, 来不断hack的人也少了。

First attempt不成功就走人。

之前你用IP-01,它的Default也是 alwaysauthreject=yes 的,為什麼會跟現在有分別呢?  可能Hacker是不同人,所以有不同的耐性。

TOP

我之前的D510MO的Asterisk server,所有settings都是自己一手一脚加上去的,所以没有自动,所以会引起多一些人才hack,最近才加上alwaysauthreject=yes后,好像hack的人少了,不过要多观测久一点才能知道结果。
