How Do Solicitors Use Phone Numbers That Are Not In Service

Criminals can steal your phone number past pretending to be you lot, then moving your number to another telephone. They'll then receive security codes sent via SMS on their telephone, helping them gain access to your bank business relationship and other secure services.

What is a Port Out Scam?

"Port out scams" are a large problem for the entire cellular industry. In this scam, a criminal pretends to be y'all and moves your current phone number to another cellular carrier. This process is known as "porting," and is designed to allow you keep your phone number when yous switch to a new cellular carrier. Any text letters and calls to your phone number are and so sent to their phone instead of yours.

This is a big problem because many online accounts, including banking concern accounts, utilise your telephone number as a two-factor hallmark method. They won't let you lot sign in without sending a code to your phone start. But, later on the porting scam has taken place, the criminal will receive that security code on their phone. They could utilise it to gain access to your financial accounts and other sensitive services.

Of course, this type of attack is nigh dangerous if an assaulter already has access to your other accounts—for example, if they already have your online cyberbanking password, or access to your email business relationship. But it lets the assailant featherbed the SMS-based security messages designed to protect you in this situation.

This attack is besides known every bit SIM hijacking, as information technology moves your phone number from your current SIM card to the attacker's SIM card.

How Does a Port Out Scam Work?

This scam has a lot in common with identity theft. Someone with your personal information pretends to be you, asking your cellular carrier to motion your phone number to a new telephone. The cellular carrier will ask them to provide some personal information to place themselves, but often providing your social security number is proficient enough. In a perfect world, your social security number would be private—but, as nosotros've seen, many Americans' social security numbers have leaked in breaches of many big businesses.

If the person can successfully fool your cellular carrier, the switch takes identify and whatsoever SMS messages sent to y'all and phone calls intended for yous volition exist routed to their phone. Your phone number is associated with their phone, and your current phone won't have phone call, texting, or data service anymore.

This is really just another variation of a social engineering attack. Someone calls a visitor pretending to exist someone else and uses social applied science to proceeds access to something they shouldn't take. Like other companies, cellular carriers want things to be as piece of cake as possible for legitimate customers, then their security may not be tight enough to fend off all attackers.

How to Finish Port Out Scams

Nosotros recommend making sure you lot have a secure PIN fix with your cellular carrier. This Pin will be required when porting your phone number. Many cellular carriers previously simply used the final four digits of your social security number as a PIN, which made port out scams much easier to pull off.

• AT&T: Ensure you lot've set up a "wireless passcode", or Pivot, online. This is unlike from the standard password you lot use to sign into your online business relationship, and must exist iv-to-8 digits. You may also want to enable "extra security" online, which volition make your wireless passcode required in more than situations.
• Dart: Provide a Pivot online on the My Sprint website. Along with your account number, this PIN will be used to confirm your identity when porting your phone number. It's separate from the standard online user business relationship countersign.
• T-Mobile: Phone call T-Mobile customer service and inquire to add "Port Validation" to your business relationship. This is a new half-dozen-to-xv digit password that must exist provided when you're porting your number. We don't know why, merely T-Mobile doesn't let you practise this online and forces you to telephone call in.
• Verizon: Set a four-digit account PIN. If you haven't already set one or don't remember information technology, you can alter it online, in the My Verizon app, or by calling customer service. You should also ensure your My Verizon online account has a secure password, as that password could be used when porting your telephone number.

If you have another cellular carrier, check your carrier's website or contact customer service to find out how protect your account.

Unfortunately, there are ways effectually all these security codes. For example, for many carriers, an attacker who could gain admission to your online account could alter your PIN. Nosotros too wouldn't be surprised if someone could all your cellular carrier, say "I forgot my PIN," and somehow reset it if they knew plenty personal information. Carriers need to take a way for people who forget their PINs to reset them. But this is all you can do to protect yourself against porting.

Mobile networks are working on lamentatory up their security. The big four United states cellular companies—AT&T, Sprint, T-Mobile, and Verizon—are working together on something called the "Mobile Hallmark Taskforce" to make porting scams and other types of fraud harder to pull off.

Avoid Relying on Your Phone Number as a Security Method

Phone number port out scams are one of the reasons yous should avoid SMS-based two-step security when possible. We all like to think our telephone numbers are completely nether our command and just associated with the phone nosotros own. In reality, that'due south only not true—when you lot rely on your phone number, you're relying on your cellular carrier's customer service to protect your phone number and cease attackers from stealing it.

Instead of getting security codes sent via text bulletin, we recommend using other two-factor security methods, like the Authy app for generating codes. These apps generate the code on your phone itself, and then a criminal would actually need to have your phone—and unlock it—to become the security code.

Unfortunately, many online services require you to utilise SMS verification with a phone number and don't provide another option. And, even when services do provide another option, they may permit you send a code to your phone number as a backup method, just in case. You tin can't always avoid SMS codes.
