Well, WC really uses SSL, and I already tried MITM-atack. No results yet(
Honestly, there are few things we can do.
Hard way: we can try to exploit a vulnerability of ssl, which allows to sign our own certificate with NOA key, so DS will trust. Yep, it IS bruteforce, but it can be completed in adequate time.
Easy way: we can try to redirect requests to non-encrypted channel. I don't think that DS will insist using SSL. If so - we can just patch rom and analyse data transferring while others will perform hard way)
