[墨者学院] Linux硬盘文件分析取证(SSH过的IP)

给出百度云地址，下载附件

给出的是一个ssh1.img镜像

还是用AccessData FTK打开

File -> Add Evidence Item...，选择 Image File

选择我们的文件地址。Finish

我们要找的是ssh过的ip，那么首先要知道系统的日志是会记录在/var/log/messages的，

那么我们去看看这个文件

Nov  1 12:39:10 localhost auth.info sshd[3898]: Server listening on 0.0.0.0 port 22.
Nov  1 12:39:10 localhost auth.info sshd[3898]: Server listening on :: port 22.
Nov  1 12:39:10 localhost daemon.info init: starting pid 3904, tty '/dev/tty1': '/sbin/getty 38400 tty1'
Nov  1 12:39:10 localhost daemon.info init: starting pid 3905, tty '/dev/tty2': '/sbin/getty 38400 tty2'
Nov  1 12:39:10 localhost daemon.info init: starting pid 3908, tty '/dev/tty3': '/sbin/getty 38400 tty3'
Nov  1 12:39:10 localhost daemon.info init: starting pid 3911, tty '/dev/tty4': '/sbin/getty 38400 tty4'
Nov  1 12:39:10 localhost daemon.info init: starting pid 3914, tty '/dev/tty5': '/sbin/getty 38400 tty5'
Nov  1 12:39:10 localhost daemon.info init: starting pid 3917, tty '/dev/tty6': '/sbin/getty 38400 tty6'
Nov  1 12:39:15 localhost daemon.info chronyd[3841]: Selected source 203.107.6.88
Nov  1 12:39:15 localhost daemon.warn chronyd[3841]: System clock wrong by 1.947665 seconds, adjustment started
Nov  1 12:40:30 localhost daemon.info chronyd[3841]: Source 85.199.214.100 replaced with 193.228.143.13
Nov  1 12:40:31 localhost auth.info login[3921]: root login on 'tty1'
Nov  1 12:40:59 localhost auth.info sshd[3923]: Accepted password for root from 172.16.110.15 port 45466 ssh2

看到sshd服务最后一次密码认证的ip是来自172.16.110.15的，所以答案就是它了。
