    • Banking Bait: May use the first few digits of your debit/credit card as bait
    • Malware Malfunction: Texts can direct you to a website that looks exactly like your bank/account and attempt to infect your phone with malware
    • Unknown & Unsolicited: Texts from unknown numbers should raise alarm bells, so call the bank/company using a number from a bank statement/verified source to investigate
    • Geographic Targets: Smishing allows for increased geographic targeting over email phishing

Don’t be fooled, technology will never save you 100% from fraudsters!
