The following are two updates for the next version of SIPVicious’s PBX extension enumeration tool svwar:
- svwar now tries to guess common numbers by default. It scans for the following ranges: 1000,2000… 9000, 1001, 2001..9001, 1111,2222… 9999, 11111,22222…99999, 100-999, 1234,2345 ..7890 and so on. This feature has a tendency to identify extensions on many PBX configurations. If you would like to disable it simply pass the –disabledefaults option to svwar.
- svwar now sends ACK responses to SIP responses with code 200 because some PBXes keep sending packets until they receive an acknowledge.
That’s it for now. Please let me know about your experience with the new features. To give the code a try simply run svn update from the sipvicious directory, or gte the latest by running the following:
svn checkout http://sipvicious.googlecode.com/svn/trunk/ sipvicious-read-only
