Crack MSN hashes?

Good morning all, After sniffing for a couple of hours an ISP network, I got a bunch of MSN Messenger traffic, like the packet below (I masked some chars to protect the guy): --------------------------------------------------------------------------- UBN xxxx () hotmail com 10 495 ACK MSNMSGR:xxxxxx () hotmail com MSNSLP/1.0 To: <msnmsgr:xxxxxx () hotmail com> From: <msnmsgr:xxxx () hotmail com> Via: MSNSLP/1.0/TLP ;branch={E6321020-D46B-4DBC-A799-BD8F1C686B6D} CSeq: 0 Call-ID: {00000000-0000-0000-0000-000000000000} Max-Forwards: 0 Content-Type: application/x-msnmsgr-turnsetup Content-Length: 144 ServerAddress: 207.46.112.175 SessionUsername: IZm4/GI6rJdhxxxxxxxxxxXaDENO5bRyJWUjvs8ChwX+BOmy SessionPassword: 7Y0pJxxxxxxxc8b8HQ/4bw== --------------------------------------------------------------------------- I was wondering how could I crack these hashes. They don't seem to be neither MD5 nor SHA. The SessionUsername has always 48 digits, and the SessionPassword has always 24. Does anyone know what type of cipher does MSN use? And is there some tool to attempt dictionary attacks against them? Please note that I am NOT talking about the stuff stored by MSN in the registry when you check the option "remember my password". I mean the hashes transmitted by MSN over the network.
