what is sim swapping and how realistic is this threat for average users?
i work in IT and I keep seeing sim swapping come up in security threads like everyone already knows what it means.
Best I can tell what is sim swapping is when someone convincing your carrier to move your number to their SIM, then they intercept your SMS codes and trigger resets. But every writeup I find is either aimed at crypto holders or completely vague about where the actual failure happens.
I've got TOTP on most accounts but a few older ones still fall back to SMS. Trying to figure out if that's a real problem or just a background noise.
is sim swapping something normal non crypto people actually need to worry about, or is the threat model pretty narrow?
