Almost all passwords and other authentication strings in Cisco IOS configuration files are encrypted using the weak, reversible scheme used for user passwords. Cisco devices can use a proprietary encryption algorithm to encrypt the password for enable mode and vty lines. This kind of encryption is used when 'service password-encryption' has been enabled on the device and produces Type-7 passwords. Cisco Enable Password Decrypt cisco secret 4 cd

(not enable secret), User passwords and most other passwords like VTY Password, Console Password, AUX Password in Cisco IOS configuration files are encrypted using a scheme that is very weak by modern cryptographic standards. Type 7 Passwords are not secure and can easily be decrypted. Cisco type 7 Password could be identifying as a password in the configuration file with a '7' in the second to last field. A Cisco Type 7 Passwords is encrypted using Cisco's weak proprietary algorithm.

Cisco Response This is the Cisco response to research performed by Mr. Philipp Schmidt and Mr. Jens Steube from the Hashcat Project on the weakness of Type 4. Cisco type 7 password decrypt hack crack. This page allows users to reveal Cisco Type 7 encrypted passwords. Crack Cisco Secret 5 Passwords. Understand the difference. The program will not decrypt passwords set with the 'enable secret' command. The unexpected concern that this program has caused among Cisco customers has led us to suspect that many customers are relying on Cisco password encryption for more security than it was designed to provide. I've got a copy of a Cisco ASA config and i want to crack the following example passwords. I've got the following lines in the config. ASA Version 8.4(2)! Hostname ciscoasa. Enable password 8Ry2YjIyt7RRXU24 encrypted. Passwd 2KFQnbNIdI.2KYOU encrypted.

UPDATE: See bottom of post for a way to run MD5 cracking on Linux

Well, I managed to find this information out by phoning Cisco directly, and since most of the information on this subject seems to be either plain wrong or incomprehensible rubbish spouted by people with no idea what checking up on facts or cross referencing is, I’ve decided to share my knowledge here:

Cisco type 5 passwords are based on FREEBSD’s MD5 function with a SALT included to make life harder; however, as a typical type 5 password also includes the SALT, it does tend to defeat the purpose of SALTing values. For example:

enable secret 5 $1$mERr$hx5rVt7rPNoS4wqbXKX7m0

Let’s break that down:

enable secret 5 This tells us that the password is an MD5 SALTed password.

$1$ Tells us that yes, it really is a SALTed MD5 password

mERr This is our SALT. From here, we can use a program to crack the MD5 hash I have used http://www.darknet.org.uk/2009/07/crack-pl-sha1-md5-hash-cracking-tool/

hx5rVt7rPNoS4wqbXKX7m0 And this is our MD5 hash

PS: I found that password hash using the Googledork: inurl:startup-config “enable secret 5”

Cisco Decode Secret 4

Black ops zombies free download iphone. Update: After some discussion with another member of my local LUG, we managed to get BarsWF MD5 (http://3.14.by/en/md5) cracker running under Wine. This is a 3 stage process

1.) Grab a copy of BarsWF (if you have CUDA, yuo will need to run it under Windows, unless you want to port it to Linux. I couldn’t get the 64 bit binary running under Wine, so ran with the x86 edition.

2.) You need a cisco type 5 password hash, of course, you already own a cisco device and have generated a SALTed MD5 hash for educational purposes, right.? Let’s assume mine is hx5rVt7rPNoS4wqbXKX7m0

Next, we have to convert the password string into a base64 encoded string. I use http://www.motobit.com/util/base64-decoder-encoder.asp But had to change the character set to windows-1250 which gave me the string aHg1clZ0N3JQTm9TNHdxYlhLWDdtMA now, we can attempt a brute force on it.

3.) Now, all we need to do is force the issue:

retrorabble@Lisa[~]$ BarsWF_SSE2_x32.exe -c 0aA~ -h aHg1clZ0N3JQTm9TNHdxYlhLWDdtMA

4.) If you are on Linux and use CUDA (or whatever ATI calls it) have a look at http://www.networkworld.com/community/node/43721or if you realy want to push the envelope: http://hashcat.net/hashcat/expect hashcat to feature in a future posting as it seems to be what I am looking for (i.e. a multi-threaded, multi core, non GPU, bruteforcer for salted MD5 passwords).
