Some interesting stuff I apparently didn't notice the first time in updates to AT&T's terms of service, which you agreed to by continuing to use AT&T. This language is designed to insulate AT&T from liability in the event someone SIM swaps your phone number and uses that to steal your identity, crypto, etc. There's quite a bit of ongoing litigation about this very subject.

https://www.att.com/legal/terms.consumerServiceAgreement.html

"AT&T is not responsible for losses incurred as a result of your or a third-party’s use of your AT&T wireless number or other AT&T Service as a source of authentication or verification in connection with any social media, email, financial, cryptocurrency or other account;"

....."To the greatest extent permitted by law, AT&T is not liable to you for any damages of any kind resulting in any way from:

the installation, maintenance, removal, or technical support of AT&T Services, even if the damage results from the ordinary negligence of our installer or other representative;
any unauthorized access to your AT&T Accounts or AT&T Services (including the use of your AT&T Accounts or AT&T Services to access a third-party account), even if the unauthorized access was the result of ordinary negligence by an AT&T employee, representative, agent, or any person or entity purporting to act on AT&T’s behalf;"

Whew, that's some heavy stuff. Meanwhile, please enjoy this latest SIM-swap rap. h/t @nixonnixoff
