Fraud Scam - Mobile Number Hijacking (Port-Outs)
Security
Jun 28, 2024
What is an unauthorized port-out?
An unauthorized port-out occurs when the mobile telephone number tied to a customer’s account is moved to another provider without the customer’s authorization. Fraudsters can use port-outs as a way to hijack your line, intercept your calls and SMS messages, and receive authentication codes from banks, cryptocurrency exchanges, and other financial institutions.
When a line is ported off of your account without your permission it takes time for the line to be recovered and returned to you. Because of this you may experience a lapse in coverage/service which can impact your day to day life.
How does it work?
Fraudsters typically complete unauthorized port-outs after obtaining a customer’s personal information via phishing attacks or by purchasing compromised account credentials through dark web marketplaces. Phishing occurs when criminals send fraudulent requests for personal information to victims, usually posing as a company or government agency.
Victims of unauthorized port-out attacks frequently have their email accounts compromised prior to the port-out, allowing fraudsters to intercept communications from phone providers.
