渗透过程中日志信息分析示例！！！

渗透过程中，我们可能用普通账号进到了系统，在提权或者进一步信息收集的过程中，我们会获得一些日志文件，根据这些日志文件我们需要进一步的分析。

下面是kali官方给的日志文件，根据这个日志，讲述一下信息收集的方法：

wget http://www.offensive-security.com/pwk-files/access_log.txt.gz

1. 目录权限升级和解压

2. 查看具体内容

可以看到这边完全是一个web的请求信息。

3. 过滤IP地址信息

root@Fkali:/tmp/test# cat access_log.txt | cut -d " " -f 1

4.过滤IP地址并去重复

root@Fkali:/tmp/test# cat access_log.txt | cut -d " " -f 1 |sort -u201.21.152.44208.115.113.91208.54.80.244208.68.234.9970.194.129.3472.133.47.24288.112.192.298.238.13.25399.127.177.95

 5. 去重后统计IP地址的访问次数

root@Fkali:/tmp/test# cat access_log.txt | cut -d " " -f 1 |sort| uniq -c      1 201.21.152.44     59 208.115.113.91     22 208.54.80.244   1038 208.68.234.99      8 70.194.129.34      8 72.133.47.242      8 88.112.192.2      8 98.238.13.253     21 99.127.177.95

6.对于去重IP地址访问次数排序

root@Fkali:/tmp/test# cat access_log.txt | cut -d " " -f 1 |sort| uniq -c | sort -run   1038 208.68.234.99     59 208.115.113.91     22 208.54.80.244     21 99.127.177.95      8 70.194.129.34      1 201.21.152.44

7. 查看第一个1000多次请求的ip地址对应log

cat access_log.txt | grep 208.68.234.99

8. 通过上面的结果，可以看出多次请求/admin这个接口，对这个接口进行统计查看

cat access_log.txt | grep 208.68.234.99 | grep "/admin" | sort -u

9. 从上面的分析可以看到，这个ip地址对/admin地址进行了爆破等相关操作，而且从结果可以看出，爆破应该已经成功了。

上面是针对日志文件分析的思路，这边也感谢yuan老师的讲解
