What is SIM Swapping?

SIM swapping is a type of identity theft where criminals trick a mobile carrier into transferring a victim's phone number to a SIM card they control. This allows the attacker to intercept calls and texts, including two-factor authentication codes, to gain unauthorized access to the victim's accounts like bank and email.

Real World Impact: In 2019, former Twitter CEO Jack Dorsey's Twitter account was hacked via this method. It can happen to anyone.
