okha Posted June 22, 2010 Share Posted June 22, 2010 well is it possible to capture the skype voip calls with arp poisioning with MITM attack? Quote Link to comment Share on other sites More sharing options...
Sparda Posted June 22, 2010 Share Posted June 22, 2010 Skype uses proprietary encryption which, apparently, has been broken by people, however, the information to decrypt skype calls is not public as far as I am aware. You could use ARP poisoning to capture all the data from a skype call however. Quote Link to comment Share on other sites More sharing options...
Infiltrator Posted June 23, 2010 Share Posted June 23, 2010 I've read in other forums that Cain and Abel is able to capture VOIP and record it to a file. Quote Link to comment Share on other sites More sharing options...
Mr-Protocol Posted June 23, 2010 Share Posted June 23, 2010 I've read in other forums that Cain and Abel is able to capture VOIP and record it to a file. I was going to mention that, but Skype encapsulates the data in it's own encryption as Sparda noted. So I don't believe Cain & Abel will recognize it as VOIP traffic.

Guest Deleted_Account Posted June 30, 2010 Share Posted June 30, 2010 Wasn't there a tool in back track for this at one point? Or was it for plain old VoIP? Quote Link to comment Share on other sites More sharing options...
okha Posted July 3, 2010 Author Share Posted July 3, 2010 Wasn't there a tool in back track for this at one point? Or was it for plain old VoIP? well i dont think there is any coz skype calls are encrypted so cain doesnt work and so does other voip tools... the megapanzer exploit is the only tool that i know which can record voip call by injecting into skype process and recording the call and sending it to web...as mentioned on megapanzer site Quote Link to comment Share on other sites More sharing options...
Carbon Posted July 14, 2010 Share Posted July 14, 2010 Wasn't there a tool in back track for this at one point? Or was it for plain old VoIP? I believe the tool in backtrack was for collecting G711 and G729 voip streams for payback which can be done within wireshark anyway. With skype they use there own codec / compression which i believe has been cracked somewhere. I know that asterisk has a skype addon so who ever built that would know the decryption...
