SIM Swap Attack — Phone Number Hijacking
Attack Trigger
Attacker socially engineers your mobile carrier to transfer your phone number to their SIM card
What Attackers Want
$10,000–$1,000,000+ in bank and crypto account losses
How This Attack Works
A fraudster calls your mobile carrier impersonating you, using personal details gathered from data breaches or social media. They request an emergency SIM transfer to a new device they control. Once your number is ported, they intercept all SMS-based two-factor authentication codes and immediately take over bank, email, and cryptocurrency accounts.
Red Flags to Watch For
- ✗Your phone loses all carrier signal unexpectedly — no calls, texts, or data
- ✗You receive a carrier text confirming an account change you did not request
- ✗Password reset emails or banking alerts arrive for actions you did not initiate
- ✗Your mobile carrier account shows a recent SIM change in the activity log
- ✗Multiple account lockout notifications arrive simultaneously across services
- ✗Someone already knew your carrier account PIN — obtained from a prior data breach
