The following example shows type 8 password found in a Cisco configuration: Essentially it is 20,000 iterations of SHA256 and this makes it much harder to crack in comparison with the previous password types. This time it really uses the PBKDF2 algorithm and 10 character salt (80 bits). This password type is a proper implementation of the failed password type 4. #Decrypt cisco secret 4 full versionXem thêm: Download Sony Vegas Pro 11 Full Version Gratis, Download Gratis Sony Vegas Pro 11 Full Version Cisco type 8 password Wget ciscot7.py -d -p 0236244818115F3348įrom the above screenshot we can see that the average speed is around 1.2 million password attempts per second. Here are some examples:įor instance, to decrypt the above type 7 password using Ciscot7 Python script, simply run: Username admin privilege 15 password 7 0236244818115F3348 Decrypt Cisco type 7 passwordThere are number of freely available tools for decrypting type 7 password. The following example shows type 7 password found in a Cisco configuration: The algorithm is reversible and thus it can be deciphered instantly into a plain text without any need for cracking. This password type uses Vigenère cipher which is essentially a simple alphabetical substitution encryption. We can clearly see that the admin user has a password of. Username admin privilege 15 password 0 As you can see, there is really nothing to crack or decrypt. The following example shows type 0 password found in a Cisco configuration: It is the oldest and the most insecure method of storing passwords in Cisco devices. Cisco type 0 passwordĬisco password type 0 is basically clear text password. 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): Cisco Passwordĭisclaimer: All examples and speed measurements in this article were produced on a standard modern laptop equipped with a GPU and 4 CPU cores. The attackers are typically looking for sensitive information such as stored credentials, SNMP community strings, network configuration details and so on.Ĭredentials 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. 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. ![]() Or we may just flat out break into some Cisco device configured with default credentials. from PuTTY) containing Cisco configuration snippets. It may be a configuration backup found laying somewhere on some computer in the network. #Decrypt cisco secret 4 how toWe will cover all common Cisco password types (0, 4, 5, 7, 8 and 9) and provide instructions on how to decrypt them or crack them using popular open-source password crackers such as John the Ripper or Hashcat.īạn đang xem: Cisco routers password typesĭuring penetration tests, it is not uncommon to come across a configuration file of a Cisco network device. ![]() In this guide we will go through Cisco password types that can be found in Cisco IOS-based network devices. ![]()
