6 Ways to Hack SNMP Password

In this article, we will learn how to gain control over our victim’s SNMP service. There are various ways to do it and let take time and learn all those because different circumstances call for different measure.

Hydra

Hydra is often the tool of choice. It can perform rapid dictionary attacks against more than 50 protocols, including telnet, ftp, http, https, smb, several databases, and much more

Now, we need to choose a wordlist. As with any dictionary attack, the wordlist is key. Kali has numerous wordlists built right in.

Run the following command

hydra -P /root/Desktop/pass.txt 192.168.1.125 snmp

-P:  denotes path for password list

Once the commands are executed it will start applying the dictionary attack and so you will have the right username and password in no time. As you can observe that we had successfully grabbed the SNMP password as ignite123.

xHydra

This is the graphical version to apply dictionary attack via SNMP port to hack a system. For this method to work:

Open xHydra in your kali. And select Single Target option and their give the IP of your victim PC. And select SNMP in box against Protocol option and give the port number 161 against the port option.

Now, go to Passwords tab and in Username section check the box adjacent to Protocol doesn’t require username.

Then select Password List and give the path of your text file, which contains all the passwords, in the box adjacent to it.

Now go to the specific Tab and in the SNMP and clear the data written in the text box below the SNMP as shown in the given screenshot.

When you will clear all entries it will look like as shown in next image given below.

After doing this, go to Start tab and click on Start button on the left.

Now, the process of dictionary attack will start. Thus, you will attain the password of your victim.

As you can see that we have the password ignite123 cracked.

Medusa

Medusa is intended to be a speedy, massively parallel, modular, login brute-forcer. It supports many protocols: AFP, CVS, FTP, HTTP, IMAP, rlogin, SSH, SNMP, and VNC to name a few

Run the following command

medusa -M snmp –h 192.168.1.125 –u ignite –P /root/Desktop/pass.txt 

 Here

-h: denotes host IP

-u: denote a particular user

But Brute forcing SNMP doesn’t require username but medusa doesn’t work without a proper syntax, you can use any username of your choice

P:  denotes path for password list

As you can observe that we had successfully grabbed the SNMP password as ignite123.

Metasploit

This module will test SNMP logins on a range of machines and report successful logins. If you have loaded a database plugin and connected to a database this module will record successful logins and hosts so you can track your access.

Open Kali terminal type msfconsole

Now type use auxiliary/scanner/snmp/snmp_login

msf auxiliary(scanner/snmp/snmp_login)> set rhosts 192.168.1.125 (IP of Remote Host)

msf auxiliary(scanner/snmp/snmp_login)> set pass_file  /root/Desktop/pass.txt

msf auxiliary(scanner/snmp/snmp_login)> set stop_on_success true

msf auxiliary(scanner/snmp/snmp_login)> run

 From given below image you can observe that we had successfully grabbed the SNMP password.

Nmap

We can also crack the snmp password using nmap, execute given below command.

nmap –sU –p 161 –n –script snmp-brute 192.168.1.125 –script-args snmp-brute.communitiesdb=/root/Desktop/pass.txt

As you can see above that we have the password cracked as ignite123.

Onesixtyone

Onesixtyone is an SNMP scanner that sends multiple SNMP requests to multiple IP addresses, trying different community strings and waiting for replies.

onesixtyone 192.168.1.125 –c /root/Desktop/pass.txt 

As you can see above that we have the password cracked as ignite123 using onesixtyone
