Recently I needed to discover out details about a Juniper router password which is definitely saved as a hásh in the routér settings. The challenging part is certainly while the security password hash will be officially a MD5 hash it is definitely modified to create it exclusive and create it harder to split.
Fortunately there is a method to crack the hash using JTR (David The Ripper) thóugh it will require that you also have got the username associated to the security password as the username can be utilized as part of the salt for the hásh. Below there is definitely first information on how to crack Juniper hashes which are usually the exact same as Netscreen hashes implemented by even more info about the hásh itself.How Tó Break Juniper Security password Hashes:To break a Juniper gadget hash you will need the hash itseIf, the username connected to the hash, and accessibility to Bob The Ripper.
First add the hash ór hashes to á text document on the machine where JTR will be located in the below structure.JTR Juniper Router Hash Text File File format. Admin:admin$nDá2MErEKCsMcuQOTsLNpGCtKJAq5nThe abové hash was created using the netscreen.py file that will be packaged with JTR which I will explain how to make use of below. The username is admin and the password for the hash is certainly QUESTIONDEFENSE. The above collection should end up being added to a text document (in this example it was added to junipérhash.txt) which wiIl then be approved to JTR to audit which is demonstrated below.
In this illustration we are heading to use a tiny wordlist that we know contains the password for the above hash.Illustration Using JTR To Split Juniper Router Passwords. Main @dev: /pentest /security passwords /john #As you can notice the password was damaged and supplied as QUESTIONDEFENSE which is usually the right password associated to the hash.
Obviously it won't become this simple to crack Juniper router passwords however it can be achievable and with time you should become able to break them without concern.Create Juniper Hashes Making use of netscreen.py:Generally there is definitely a python software that arrives with JTR known as netscreen.py. Which had been developed by Samuel Monux (information obtained from JTR mailing checklist). The script will create Netscreen and/ór Juniper hashes whén exceeded a username and password on the order line.
Below is a fast illustration of what has been carried out to develop the illustration hash used above. Main @dev: /pentest /security passwords /john #Juniper Security password Hash Details, NS MD5, md5ns:Thé Juniper security password hash will be better identified as the Netscreen security password hash and information can also be situated by searching fór NS MD5 ór md5ns. Thé following details about the hash were attained from the JTR mailing listing in a write-up by Samuel Monux who furthermore developed the netscreen.py script stated above. The hash is certainly a natural MD5 hash with some modifications to make it unique.
I don`t have direct access to the Router so its difficult for me to deploy my application on router and test it. Can Juniper provider any simulator etc. Where we can test our applications. I do have the junos sdk ui simulator version 'junos-sdk-ui-sim-11.2R2.4-signed.tgz' which I already installed on my VBE. I'm looking to begin my CCNA studies. I intend to buy some equipment off eBay and eventually create a lab. In the meantime, and to assist in a prompt start to my studies, does anyone know what software is the best to use that will replicate Routing & Switching?
The hash is usually furthermore salted with the username simply because well as a cónstant of (“:Administration Tools:”). The 128 pieces of thé MD5 hásh in 16 little bit chunks divided into 4 pieces, 6 pieces, and 6 pieces and then indexed in an selection using every character in the subsequent range, A-Zá-z0-9+/ all of which is certainly a bit over my mind.:) Then the characters ntscrn backwards are usually put into positions through the hash to make it even more distinctive. They are always put at opportunities 0, 6, 12, 17, 23, and 29 in the hash output.I have always been looking at methods to complete these hashes to an program that uses GPU't and as soon as productive I will up-date this content or create a fresh post and benchmark this 1.

Several labs are usually available for thorough hands-onpreparation. Router console simulation: Routerconsole (running Junos™) is certainly obtainable in a simulatedenvironment. Currently 50+ IOS router commands are supported.
Itis anticipated to give great hands-on knowledge to those who do not really haveaccess to Junipér routers for understanding purpose. Comprehensive help document: The complete simulator isexplained in an easy to use help file. The areas covered in the helpfile consist of 1. Recognized commands, 2. How to get around through the Iabexercises and router gaming console simulator, 3. Disclaimer. Display cards: Adobe flash cards are usually accessible whiletaking several lab workouts.
These offer topic assist, and helpful inproperly responding to the labs. SimuIator: Configure router networks with50+ supported instructions.
