Main threats

Fraudulent wire transfer requests (CEO wire transfer scam)

Understand it

The CEO wire transfer scam involves a fraudster impersonating a senior executive at your company and asking one of your employees to carry out a wire transfer for a large, urgent, and—most of all—confidential transaction. The fraudster may also use different identities (e.g., lawyer, notary) in order to make the transaction seem more legitimate.


Recognize it

Indicators of a CEO wire transfer scam:

  • The wire transfer request is urgent and/or confidential.
  • The transfer has to be completed the same day (e.g., before 3 p.m.).
  • The wire transfer request is received towards the end of a regular workweek.
  • The beneficiary of the wire transfer is a company that you have never done business with.

How to protect yourself from a fraudulent wire transfer requests

Being vigilant will help attempted fraud to be quickly detected. Some preventive measures:

  • Implement an internal procedure for handling requests with similar indicators to those above.
  • Establish verification, validation in person, and multiple signatory procedures for wire transfers.
  • Pay special attention during vacation periods; companies tend to receive more fraudulent emails during these times.

If you have been or suspect you have been a victim of fraud, contact us as soon as possible at 514 394-5555 or toll free at 1 888 835-6281.

Phishing (e-mail and text scams)

Understand it

Phishing is a technique where dishonest individuals send out e-mails to try to obtain personal information about people.

Phishing scams can also be sent via text message; such scams are known as SMS phishing or smishing. The same recommendations apply as for e-mail phishing.


Recognize it

Users of online commercial sites, payment organization sites and financial institution sites may all be the target of this practice. The messages contained in scam e-mail look like they originate from recognized sources. Moreover, the websites used by phishers are generally very good at imitating legitimate sites whose logos users readily recognize.

Want to know more about phishing? Visit the E-mail Fraud/Phishing section of the Canadian Bankers Association website.

How to protect against phishing?

Do not reply to these e-mails or text messages

Be careful: if you receive an e-mail or text message that seems to come from National Bank or MasterCard asking you to provide personal information or notifying you that you will be receiving a transfer of funds from someone you do not know, delete it. It’s probably a scam.

picto croix

Never click on hyperlinks

Whether it’s an e-mail referring to contest winnings or any other alleged urgent reason, never click on hyperlinks, and don’t copy and paste them into your browser.

picto croix

Don’t provide the requested information for any reason

Neither National Bank nor MasterCard ever use this method to ask for your personal or banking information, such as credit card numbers, passwords or your mother’s maiden name.

Secure your equipment

Remember that it is essential for you to protect your computer by installing suitable protection software, and keeping it up to date automatically, including anti-virus, anti-spyware and firewall software, so as to bank with confidence.

picto coche ok

If you think you have been the victim of fraud, contact us

If you have any suspicions, consult the Report an incident of fraud section and call us at 1-888-835-6281 or 514-394-5555.


Understand it

Malware means a program or software designed to enable unauthorized persons to access a system to disrupt its operations or to change or steal data.


Recognize it

Malware can be difficult to detect, as it generally does not appear on the list of installed programs. It can be installed inadvertently and cause damage without our knowledge, as it is similar in appearance to pages we are used to viewing. It can be installed inadvertently by downloading certain free software in which it resides, by visiting certain websites or via peer-to-peer file-sharing.

You may have malware on your system if:

  • Your equipment is performing more slowly than usual or seems less responsive.
  • You are automatically redirected to a page whose address you did not enter into your browser.
  • You are constantly bombarded with pop-up advertisements.
  • A new page suddenly appears, asking you to provide personal or financial information for authentication, which is not normally the case. You may also notice a suspicious or unusual formulation in the new request.
  • New tools or icons suddenly appear in your Internet browser, or the settings for your homepage change.
  • Your equipment crashes or freezes more frequently.

For a mobile device, you may notice unusual text messages or a sudden drop in the lifespan of your battery

How to protect against malware?

Malware is practically invisible and can be reactivated at any time. To prevent any problems:

  • Avoid downloading any documents or applications from unfamiliar or suspicious sources.
  • Only do business with trusted sites. You should contact the provider if, while visiting a trusted website, you encounter a new situation or notice changes in your usual procedures, without having received any prior notice of such change. You should also contact the provider if you are asked unusual or strange questions. Also, you should immediately contact one of our representatives at 514 394-5555 or at 1-888-835-6281 if you notice anything abnormal while using our Electronic Banking Solutions. If you have any doubts whatsoever, you should never hesitate: prevention truly is better than cure, so you should always be on the lookout!
  • Install anti-virus and anti-spyware software.
  • Install a firewall.
  • Run the automatic update and clean up features of your computer.
  • Regularly verify bills from your telecommunications supplier to detect any unusual activity.

Identity theft

Understand it

Identity theft is on the rise. Unlike other types of fraud, identity theft can occur whenever a criminal gains access to a person’s means of identification, regardless of whether the victim is aware of that access. This information could be obtained if the victim's wallet is stolen or by using malware to unlawfully capture information on a computer, smartphone, or another device.


Recognize it

You stop receiving certain account statements in the mail.

You now have trouble accessing credit.

You receive bills for purchases you didn’t make.

You receive visits or calls from collection agencies demanding payments from you.

How to protect yourself against identity theft

When choosing a password, avoid using information such as your date of birth or the last digits of your social insurance number (SIN) or phone number, as these can be easily discovered.

Good practices

Manage your password and secret questions carefully

Choose your password carefully

Try to choose a password that will be easy for you to remember, but hard for anyone else to guess. 


Choose a password for the sole purpose of banking online

To change your password, simply go to the Profile section of Internet Banking Solutions or Mobile Banking Solutions while you are logged in.


Avoid choosing a password based on personal information

Avoid using your first or last name, the names of your spouse or children, your date of birth, social insurance number, phone number, licence plate, name of a sports team, bank access codes, etc. Although easier to memorize, these passwords are more likely to be discovered by malicious individuals.


Do not write your password down

If you absolutely have to, write it in such a way that only you will be able to recognize it, and keep it in a safe place.

Do not save your password on your equipment


Never tell anyone your password

This rule applies even to members of your family and anyone claiming to be a National Bank employee.

Remember, your password is like the key to your house. You must take all the necessary precautions to prevent it from falling into someone else's hands.


Forget your password?

If you can’t remember your password and you didn’t provide answers to the secret questions, call one of our Customer Service Representatives at 1-888-835-6281 or 514-394-5555.

The representative will assign you a temporary password so that you can access Internet Banking Solutions. You must then choose a new secure password in order to continue.

Secret questions - Internet Banking Solutions

By answering the secret questions when you create your password (or by accessing the Profile section of Internet Banking Solutions), you can still access your account on your own, even if you forget your password.

If this happens, simply click on I forgot my password on the Internet Banking Solutions login page and correctly answer the questions. The system will then allow you to choose a new password so you can access the site.

If you can’t remember the answers to your secret questions, you can contact one of our Customer Service Representatives by calling 1-888-835-6281 or 514-394-5555.

If you can’t remember the answers to your secret questions, you can contact one of our Customer Service Representatives. As a security measure, the I forgot my password function is not available via Mobile Banking Solutions. You can contact our Customer Service Department at 1-888-835-6281 or 514-394-5555 to obtain a new password.

Note that you can change your secret questions or their answers at any time by accessing the Profile section of Internet Banking Solutions.

Clear your browser cache

It is very important to clear the cache of your browser to safeguard the confidentiality of your financial information and improve your Internet browser’s performance.

We recommend that you clear your browser cache each time you log out of Internet Banking Solutions. This is particularly important if the computer you use for your transactions is shared with other users, especially in public places, such as Internet cafes, public libraries, etc.

Download the latest version of your Web browser

Downloading available updates for your browser and operating system will make sure your Web-browsing experience is secure, as you will benefit from patches, which improve your software’s effectiveness at protecting you from a variety of common threats and security vulnerabilities.

Secure your wireless network

Change your wireless network’s default settings to create an identifier and password that would be difficult for criminals to guess.

Choose 128-bit encryption to ensure your network is sufficiently protected from possible intrusions.

Choose a strong encryption protocol, such as WPA or WPA2, that will adequately protect your network against possible intrusions.

Using a public Wi-Fi network

If possible, use your mobile device’s 3G network, rather than a public Wi-Fi network.

Follow the basic rules for doing business safely

Do not remain connected to the Internet unnecessarily.

Never leave information displayed on your screen if you leave your computer, and do not leave your equipment unattended. Always lock your computer or mobile device when it is unattended.

Don’t download or install freeware, shareware or demo software from an unknown source or questionable site. Only use authorized and official applications from recognized suppliers on your mobile device; the operating system must be legitimate and must not be altered (it must not be jailbroken, rooted or pirated).

Never run an executable (.exe) file received by e-mail unless it is from a known and trusted source.

Be careful what you throw in the recycling bin. Shred all documents that contain your financial information, such as statements, credit card offers, receipts or insurance forms, to prevent identity theft.

Send funds safely with Interac e-TransferTM

Update your contact information

Verify the e-mail address entered in your online banking profile and make sure it is up to date. Transaction confirmations will be sent to this address.


Verify the recipient's information

You are responsible for verifying that the recipient's e-mail address or cell phone number entered for the transfer is correct. Always double-check this information before submitting the transaction.

National Bank recommends that you contact the recipient to inform him or her of your intentions to transfer funds.


Choose a good security question

The security question is an additional security measure used to authenticate the recipient. It is therefore important to select an appropriate question. Choose a question that only you and the recipient know the answer to. Do not choose a question with an obvious answer that could be easily guessed by a malicious person.


Examples of poor security questions:

What colour is the sky?

How many fingers do you have?


Transmit the security answer safely

Call the recipient or speak to him or her in person to communicate the security answer. Do not leave the recipient a voice message that includes the security answer.

Never send the security answer by e-mail.


Do not indicate the security answer in the transfer message.

For example: Do not write, "Hi Diana, here is the $500 transfer as agreed. The security answer is X8T30987."


Secure your workstation

Your workstation must be protected against malware. For more information, please consult the "Protect yourself from fraud" section.


Protect the recipient's personal information

Never leave the information displayed on your screen if you leave your computer. Always lock your computer when it is unattended, and never print out the page containing your recipients' personal information.


Be vigilant

If you receive an e-mail confirmation for a transaction you did not initiate, call our Customer Service immediately at 514-394-5555 or 1-888-835-6281.


Be careful when receiving transfers

Watch out for fraudulent e-mails and text messages (phishing).

If you receive an e-mail or a text message stating that someone wants to transfer funds to you, but:

  • You do not know the sender
  • You were not expecting the funds

Never click on a hyperlink contained in such an e-mail or text message. It could be a fraudulent e-mail or text message (phishing) and may contain a virus that could compromise your browser or allow malicious persons to remotely control your computer.


Protect the required security answer

Never enter the security answer provided by the sender in your computer or mobile device (in a Word or Notepad document, spreadsheet, etc.) or leave it on a note near your computer.

Tools and downloads

Security software

We strongly recommend* that you install appropriate security software on your equipment. Note that it is also very important to update this software regularly. Software that is not kept up to date will be unable to recognize the most recent viruses and other threats.

Updating your equipment

Updates from software manufacturers should be applied regularly, especially when a vulnerability is publicized in the media. In particular, we strongly recommend* that you install the security patches for the software you use.
