任务信息

解密客户信息

实战演练

原文再续，书接上文s1.100的系统

信息收集

netdiscover发现IP是192.168.1.110

嗯。。。开了ssh，用上一次获取到的密码登录一下

登录bbanter失败，看来是密码不对

那就只能从FTP入手了，使用ftp的anonymous扫描，发现存在anonymous账号

登录

下载shadow和core文件

查看文件

将core的内容提取出来保存为passwd，然后爆破

root:$1$aQo/FOTu$rriwTq.pGmN3OhFe75yd30:13574:0:::::
aadams:$1$klZ09iws$fQDiqXfQXBErilgdRyogn.:13570:0:99999:7:::
bbanter:$1$1wY0b2Bt$Q6cLev2TG9eH9iIaTuFKy1:13571:0:99999:7:::
ccoffee:$1$6yf/SuEu$EZ1TWxFMHE0pDXCCMQu70/:13574:0:99999:7:::

后来发现root密码不是这个，再找了另外一个字典爆破

#字典
https://raw.githubusercontent.com/danielmiessler/SecLists/master/Passwords/darkc0de.txt

使用root账号进行远程登录，失败

那就只能使用bbanter账号登录，然后再提权

找到加密文件
