But this is concerning. SMS intercept? What? I know there's info on this, but it requires knowledge of how all that incredibly complicated cellular stuff works, and I kinda assumed it was secure enough since so many sites rely on it.
Mobile providers need to STOP allowing their reps to have remote access over the web to their network switches! Many have over the last decade or two ... but many still allow it. sad really. There are tools though.
Time for:
a) POTS routing system to receive a massive secure upgrade
b) companies to stop relying on SMS as a second factor
You and me ... we are here
