Fraud Scam - Mobile Number Hijacking (Port-Outs)

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.

How do you report a port-out scam?

If you’re concerned that you’re a victim of a port-out scam:

  • Notify your phone carrier immediately. 
  • Contact your financial institutions. 
  • File a police report.  
  • Place a fraud alert on your credit report. 
  • Get copies of your credit report to verify recent activity.

How do you prevent port-outs?

  • Preventing port-outs starts with guarding your personal information from hackers.
  • Protect yourself by being proactive. Add a PIN and/or password for accessing your accounts at Harborstone. 
  • Stay vigilant by enabling text and email account notifications for transactions. If you receive a notification of an unauthorized transaction, call and notify us of the changes immediately.
  • Don’t respond if someone calls or texts you asking for personal information. Be aware that the caller may replicate your financial institution’s number.
  • Don’t overshare; safeguard personal details that may be used to verify your identity.
