A short file was created containing example passwords. This is obviously not recommended, but helps to illustrate the use of this tool. The SIP phones were provisioned with passwords that were the same as their extensions.

We enabled authentication for the SER SIP proxy to illustrate use of the authtool tool (and for subsequent registration hijacking examples).

We showed an example of how to use Cain and Abel for SIP hash cracking in Chapter 6. Noteīoth SiVuS and Cain and Abel also provide SIP hash-cracking functions. Even if multiple occurrences of a username did identify the same person, that user's password might be different in different authentication realms.
That username might identify the same person or it might not, so a simple check for username repeats is insufficient in any case. In fact, the same username may be provisioned in different authentication realms. The tool is stateless in that it does not check for username repeats as it encounters SIP responses with Authorization header lines. The From: header's URI is output with the username/password solution. The user's URI is typically in the From : header line. The REGISTER request line has the URI of the proxy server or registrar, not the URI of the user whose authentication was challenged. For example, the INVITE request line contains the URI of the person being invited into a call, not the user whose authentication was challenged. The uri parameter from the Authorization line does not necessarily identify the user whose password has been determined. The URI output with the username/password solution is not the one extracted from the Authorization line uri parameter. If the r switch and a filename have been specified on the command line, then the results are also written to that file.
When it encounters a password that results in the same MD5 digest product as the digest string found in the Authorization header line, then the username, the password, and the From URI are printed to the standard output.
The tool performs a dictionary attack using a list of passwords or a single password, as specified on the command line. The tool recomputes the digest as directed by command-line options. When an Authorization header line is encountered, the authtool tool extracts the parameters required to recompute the MD5 digest that must also be present on that Authorization line. Before encountering an Authorization header line, the tool expects to find at least one REGISTER (or INVITE, OPTIONS, and so on) request line and at least one From : header line. The username/password pair(s) produced by this tool can be used directly and/or for registration hijacking. The authtool tool attempts to determine the password for each user referenced in a set of provided SIP requests and responses. Optional Parameters: -r OutputFilename A file to which results are written. d Dictionary A text file containing passwords to guess OR. authtool sip_messages.txt d dictionary_file.txt Mandatory parameters: SipFilename A file containing SIP requests to scan for MD5 hashes to attempt to crack. authtool SipFilename d Dictionary p Password r OutputFilename v Usage Example.
