Q #2) How does Password Cracking apps work?Īnswer: These applications make use of different methods for recovering passwords. Additionally, password cracking tools also help in finding out vulnerabilities in web applications. Others recover the passwords from a file stored in a local or remote location. FAQs About Password Cracking ToolsĪnswer: These tools use different techniques to recover forgotten passwords. If a free trial is available, you should try the software to test the features of the application. The best password cracking tools use sophisticated techniques for recovering their passwords. If you are in need of a penetration test or other security consulting services you can contact her at or visit the Secure Ideas – ProfessionallyEvil site for services provided.Pro Tip: You should look at the techniques used for recovering passwords. Now that you’ve seen how incredibly easy it is to reverse these types of passwords, please go forth and check your routers! Ensure that all user accounts and enable passwords listed in the running config are proceeded by the word “secret”.ĭonna Fracarossi is a Security Consultant with Secure Ideas. Finally, we do a show command, and voila! Passwords! Make sure to increase the key count though (key 2, key 3, etc.).ĥ.
* At this point, you may add more keys by repeating steps 3 and 4 if you have multiple passwords to reverse. Then we enter the key-string, which will include the number 7 for encryption type and the text of the “encrypted” password: Next, we will create our key chain and give it the name of NEW:Ĥ. There are several different tools and websites that have this capability, but there’s an easier way! I don’t even have to leave the router! Thanks to a nifty little feature called the “key chain”, I can reverse these passwords right here, right now!Ģ. So now that I’ve found these Type 7 passwords, I need a way to reverse them. This policy applies to both user accounts and passwords applied to the VTY or Console lines. Due to this, it is never a good idea to use Type 7 passwords. Type 7 passwords use a very weak algorithm that can be easily reversed, but the “secret” command utilizes a MD5 hash which is much more secure. The difference between these two storage methods ( password or secret) are the hashing algorithms. Whereas, the second user was created with this command: This is because the first user was created with a command like this: Note that both of these accounts have the same privilege level, but that the passwords are stored differently.
The fact that they were using default cisco/cisco credentials made me cry a little inside, but wait, it gets worse… So I’m in the router, reviewing the running config, and I notice something interesting. While working on a recent pen test, I came across a few Cisco routers sitting on an internal network.
