SIM Swap Attack
A social engineering attack where a hacker transfers your phone number to their device to bypass two-factor authentication.
Explained Simply
In a SIM swap attack, the attacker contacts your mobile carrier and convinces them to port your phone number to a new SIM card. Once they control your number, they can intercept SMS verification codes to access your exchange accounts, email, and other services. High-profile crypto holders have lost millions to SIM swaps. Protect yourself by using authenticator apps instead of SMS 2FA, setting a carrier PIN, and keeping your phone number private.
