Um, excuse me?

Opera Mini decrypts SSL at their site, then forwards it on to your mobile handset.  Excuse me?

The only reason I can imagine that this isn’t the biggest security uproar in recent memory is that the Opera Mini market share isn’t big enough to have caught anyone’s attention yet.

Did you get that, world?  If you use Opera Mini, they are decrypting your traffic in their own, private network, “adding value” to it by reformatting, then forwarding it on to you. It’s a purpose-built man-in-the-middle attack, for fuck’s sake.
