The Cellphone Number Porting Scam
Your cellphone number may be your most important and sensitive number to protect in our age of two-factor authentication.
Text messages are often used by financial institutions, payment services, businesses to verify yourself. Text messages are also used to verify identity when recovering passwords for shopping sites, social media, and more.
The problem? It is surprisingly simple for scammers to hijack your cellphone number through a porting-out scam.
A phone port scam scenario:
You receive a text message from your cellphone company saying your phone number will be ported in 10-minutes unless you call to cease it. If you are fortunate to be looking at your phone at this point, you may call confused, but you are more likely to delete the text thinking THAT is the scam.
You go back to your normal routine, and two hours later, your phone loses cellular connectivity.
You call to learn your phone number has been transferred (ported) to another phone. To remedy the issue, you are asked to visit a local cellphone provider store to prove it is you. This process could take hours to complete and get your number back.
By this point, it is already too late. The scammers could access your phone and use it to verify you on sites like Amazon and others. They were also likely able to use the two-factor authentication to reset the password on your email account and more.
Before you can patch up the holes, the scammers have successfully made significant online purchases and scrapped all email data they could find. They could also aim to drain your bank account or hold your sensitive and personal information (like photos, email account access, social media page access), hostage.
This is the scenario detailed in a recent episode of The Current.
How does the phone porting scam happen?
For the most part, scammers need to discover your cellphone company PIN to port your number. To do this, scammers will go after your personal information (name, address, birth date, etc.), the last digits of your social security number, answers to common security questions (mom’s maiden name, pet name, school name, favourite sport) and more to uncover information that may lead to discovering your pin or being able to reset it. They may start collecting this information by searching social media, calling you, and pretending to be a trusted professional business (like your bank) to have you slowly leak more information. They also search the dark web to find out what information about you may already be for sale.
These scammers then call your phone company and pretend to be you. If successful, the number is ported. Sadly, it is this easy. Canadian phone carriers are required to follow this legislation. It was initiated to help consumers move to a different carrier, but now scammers expose the vulnerability.
Ways to mitigate risk and protect yourself from phone porting:
- Have a pin: Make sure you have a phone pin with your cellphone provider. Call and confirm you have one set up.
- Be unique: Make your cellphone company pin code unique from other pin or common numbers (like your debit card pin, year of birth, year of child’s birth).
- Stay aware: if you see suspicious text and/or email verification requests, contact the company immediately to confirm that it is not you making that request.
- Don’t communicate: if a company calls or texts you requesting personal information, do NOT give it to them. If you are not sure if the call is legitimate, search online for the company number, hang up the call and directly call back the company.
- Keep private: Do not share answers to common security questions on your social media, write out any part of your social security number or provide any information publicly that allows someone to gather the more necessary information to con the phone companies.
