Cisco secret 5 decrypt tool

They are a one-way MD5 hash. Other than brute force, I am not aware of any attacks that are useable. Keith W. Luc D. Thats why I said 'enable secret' Regular enable passwords are easily reverse engineered. Leroy Ladyzhensky. Leroy, level 5 is enable secret, level 7 are regular enable passwords --C.

Yup, GetPass does level 7 only. Oleg Malkov. Try for yourself During penetration tests, it is not uncommon to come across a configuration file of a Cisco network device. It may be a configuration backup found laying somewhere on some computer in the network. It may be a console log output e. Or we may just flat out break into some Cisco device configured with default credentials. The first thing attackers do after they gain access to a Cisco device is that they pull current configuration from the device either by running show running or show running-config command.

The attackers are typically looking for sensitive information such as stored credentials, SNMP community strings, network configuration details and so on. Credentials are naturally the most interesting thing to look for and over the years Cisco has developed number of different methods for storing passwords in their devices.

Hence the name Cisco password type. In the following sections, we will go through all these password types by order from the least secure most easiest to crack to the most secure hardest to crack :. Disclaimer: All examples and speed measurements in this article were produced on a standard modern laptop equipped with a GPU and 4 CPU cores. Cisco password type 0 is basically clear text password. There is no encryption nor obfuscation.

It is the oldest and the most insecure method of storing passwords in Cisco devices. It should never be used. As you can see, there is really nothing to crack or decrypt. We can clearly see that the admin user has a password of [email protected]. The algorithm is reversible and thus it can be deciphered instantly into a plain text without any need for cracking.

There are number of freely available tools for decrypting type 7 password. Here are some examples:. For instance, to decrypt the above type 7 password using Ciscot7 Python script, simply run:. We can instantly see that the password is [email protected]. There are also numerous decrypters online for this type of password. But we strongly discourage using any them in order to avoid disclosing sensitive customer information credentials to a third party.
