AI Summary

SIM swapping attacks, where fraudsters move a victim’s phone number onto a SIM they control to intercept calls and texts, have risen sharply in recent years. The technique lets attackers capture two‑factor authentication codes and potentially hijack the victim’s mobile account and any services that rely on that authentication. Mobile carriers have begun offering settings that can block such attacks, but these protections are not enabled by default on most phones. Users are advised to locate and activate the carrier‑specific security options to reduce the risk of SIM‑swap fraud.
