Unbelievable Carrier Security

"An alarming test carried out by Princeton shows that the five largest US carriers fail to properly protect their customers against so-called SIM-swap attacks."

Given my experience, and I suspect many others, with the CS reps from the big carriers, this security failure is quite believable, which can be a very lucrative business for crooks and devastating financially and otherwise for the victims. Let's hope the Princeton study and the 1.8 million dollar lawsuit against AT&T will bring about foolproof security measures against sim swaps.
