Ontario residents are being warned about a relatively new kind of fraud calling "SIM swapping" in which criminals steal personal information via mobile phones in order to gain access to bank accounts.

The Ontario Provincial Police, along with Ontario's Serious Fraud Office and the Canadian Anti-Fraud Centre, saysthis kind of fraud is concerning and incidents havebeen reported to police. The fraud involves the use of "phone number porting," police said.

"Fraudsters may empty your bank accounts, apply for credit in your good name, or impersonate you to defraud your entire contact list. In the meantime, you lose access to your mobile service, are typically locked out of all your accounts, and are left scrambling," the OPP says.

A "fraudster" will impersonate a person and call their mobile service providerto report alost or stolen phone, the OPP said. Then, the fraudsterwill link the victim's phone number to a new SIM card and device that they control.

At that point, the fraudster will download a series of popular apps and will select the "forgot password" button on all of them.

If an account is connected to a phone number oremail address, the fraudster will receive a verification code. They then use the codeto confirm ownership ofthe account, create a new password and take over the victim's accounts, police said.

From there, they gain direct access topersonal information, police said.

Ways to protect yourself, police say

But the OPP says there are ways that people can protect themselves. These include:

  • Keep all personal information personal. It is as simple as not publishing adate of birth on social media.
  • Do not answer phishing emails or text messages askingto confirm apassword or update account information.
  • Use an offline password manager.
  • Contact aphone provider and ask about additional security measures that may be available.
  • If you lose mobile service on your device, contact aservice provider immediately.

"Go with your gut. If a message seems fishy, it probably is," the OPP said.

Anyone who is a victim of fraud is urged to call police.

When aSIM card is swapped, the victim can still use some aspects of theirphone and connect to WiFi,but he or shecannot make or receive phone calls, text, or use cellular data.

SIM cards, or subscriber identification modules, are used by cellphone carriers to store information on services about a subscriber's identity, the OPP said.

Through a SIM card, a phone number and a mobile service areconnected to a particular mobile device. A subscriber thenconnects dozens of accounts to his or hermobile devicethrough the use of apps.

Manylogins of these accounts are often linked to an email address, a phone number, orboth, police said in the release.
