CCC | Second Factor SMS: Worse Than Its Reputation

@linuzifer @Martin Seeger am I wrong but this story sounds not really new to me and doesn't surprise or shock as it should? Because this type of problem is somewhat at least five years or more old? There were some findings about the SS7 protocols especially when UTMS was rather new?
@hmark That the content of SMS is being stored for years by a subcontracted 3rd party with SMS being used for authentication is worse news than normal.
@hmark I have a very strong feeling that you did not read the article completely.
