If a bank alert asks you to click a link or call a number in the message, stop. Open your bank app directly or call the number on your card to verify.

Bank fraud alerts exploit something real: banks do send fraud alerts. You probably have legitimate ones in your message history right now. When a scam message arrives looking identical to the real ones, your defenses are already down.
The psychology is powerful. When someone tells you your money is at risk, your instinct is to fix it immediately. That urgency - the need to act now - is exactly what scammers exploit. They want you to click or call before you question whether the message itself is the threat.
Many people believe that if their phone shows the call is from their bank, it must be legitimate. This is dangerously wrong.
| Spoofing Method | How It Works | What You See |
|---|---|---|
| VoIP Caller ID Spoofing | Scammers use internet phone services that allow setting any outgoing caller ID | Your bank's actual phone number appears on your screen |
| SMS Sender ID Spoofing | Text message sender names can be set to almost anything | "Chase Alerts," "Wells Fargo," or your bank's name |
| SIM Swapping | Scammers transfer your phone number to their device | They receive your calls and texts, including verification codes |
The number on your screen proves nothing. A call that appears to be from Chase, Wells Fargo, or Bank of America could originate from anywhere in the world.
What the message says:
"ALERT: A $847.32 charge at AMAZON was declined. If this was not you, call 1-888-XXX-XXXX immediately."
Why people fall for it:
Safe response: Open your banking app and check recent transactions. If there is a problem, your app will show it. Do not call numbers from text messages.
What the message says:
"Wells Fargo: Unusual sign-in from IP 192.168.XX.XX (Moscow, Russia). Click here to secure your account: [link]"
Why people fall for it:
Safe response: Go directly to your bank's website by typing the URL yourself. Check security settings and recent login activity there.
What the message says:
"Your debit card ending in 4532 has been locked. Reply UNLOCK or call 1-800-XXX-XXXX to restore access."
Why people fall for it:
Safe response: Try a small purchase with your card, or check your banking app. If locked, your bank will have notifications in your account.
One-time verification codes are the last line of defense for your accounts. Scammers know this - which is why bank scams increasingly target these codes.
Critical rule: No legitimate bank employee will ever ask you to read a verification code to them. If anyone asks for a code you received, hang up immediately.
| Risk | What It Means | Impact on You |
|---|---|---|
| Credential theft | Scammers capture your online banking login | Full access to view accounts, add payees, initiate transfers |
| One-time code capture | Scammers bypass your two-factor authentication | They complete the login you blocked and take over your account |
| Account takeover | Scammers change your password, email, and phone number | You are locked out; recovery takes days or weeks |
| Wire transfer fraud | Scammers initiate transfers to accounts they control | Money is gone within hours; recovery is rare for wire transfers |
{{component-tips}}
Bank phishing pages are designed to be indistinguishable from the real thing. Same logo, same colors, same login form, same URL structure. The only difference is where your credentials go when you hit submit.
Guardio provides protection at the critical moment:
{{component-cta-custom}}
Not always, but treat messages with links as high risk. Verify through the official bank app or known numbers.
Open the bank app directly or call the number on your card. Do not rely on text links.
Change your password immediately, enable additional security, and contact your bank through official channels.
Codes can let them sign in as you. Never share codes.
Do not reply if you are unsure. Verify in the app or by calling a known number.
Guardio can warn you about suspicious links and lookalike sign-in pages before you interact.
