How does the Bank of Montreal(BMO) Scam work?
The scammers send emails or text messages to their potential victims, or call their potential victims' numbers and leave a voice message, asking them to call the fake telephone numbers. If the potential victims call the numbers, they will be asked by a human or an Automated Interactive Voice Response system to enter their credit card and other information. If the requested information is entered, it will be sent to the cybercriminals behind the scam, who will use it fraudulently.
Therefore, BMO customers who have been tricked by the scam are asked to contact BMO for help immediately at the telephone number at the back of their cards.
