SIM-Swap & Phone Hijacking Defense
SIM-swapping, convincing a carrier to move your number to an attacker's SIM, defeats every SMS code standing between criminals and your bank, email, and crypto. The January 2024 SEC X-account hijack via SIM swap proved no target is too prominent. Defense means carrier PINs, app-based 2FA everywhere, and removing your number as a recovery method wherever possible.
Key points
- Set a carrier account PIN/passcode and require it for SIM changes and port-outs.
- Move every important account from SMS 2FA to authenticator apps or hardware keys.
- Remove phone numbers as recovery options where email plus authenticator suffices.
- Treat port-out and SIM-change notifications as emergencies, respond in minutes.
- Limit public exposure of the number tied to banking and primary email.
- Ask carriers about port-freeze and number-lock features and enable them.
- Keep a printed recovery sheet for email and financial accounts off-phone.
- Brief family admins and school staff, one swapped staff number can cascade.
Field note
Set the carrier PIN today, it takes one call and closes the attack that bypassed SMS codes for the SEC itself. Then move important accounts off SMS 2FA at leisure.
