Online password cracker11/22/2023 ![]() ![]() ![]() INVITE), the extensions flag sets the From address rather than the To address. When it comes to methods other than REGISTER (e.g. In this case, the extensions flag specifies the To address in the SIP message. In such cases one can make use of the from flag to specify who is registering which extension or SIP URI that is passed to the extensions flag. ![]() In the case of the REGISTER SIP method, the From and To address are typically the same unless the SIP registrar allows for third-party registration. Special warnings are generated when the response code is unknown (e.g. Other 4XX, 5XX or 6XX responses indicate that a password cracking attack is not possible. When the response to a SIP message without an authentication header is a 200 OK, instead of a 401 or 407, this means that no authentication is required. It does this process until the password generators run out of passwords to try, or until all target extensions have resulted in a 200 OK indicating that their password has been cracked. If a 401 or 407 response is received as the new response, it then moves on to the next password from the password generators. When a 401 or 407 response is received, it then computes the authentication challenge response using the digest authentication mechanism and sends the same SIP message with the challenge response. The tool starts by sending a SIP request to the target, then waiting for a 407 or 401 response, with the default SIP method being set to REGISTER. Multiple generators can be used in combination in each attack. By default, the tool uses the pattern cracking algorithm as a password generator, using the basic extension based algorithm. The tool makes use of a number of password generators which are used to produce passwords that are then used in each password guessing (or cracking) attempt. It supports various SIP methods, password guessing techniques, distribution of the attack across different targets and across different extensions. The SIP online cracking tool attempts to guess SIP account passwords on a target SIP server. Proxies to discover guessable passwords and demonstrate security issues in weak password This tool allows various types of password cracking attacks on SIP registrars and Test SIP account weaknesses through a password guessing attack.
