Build a Secure PCWhat is SMSishing?
SMSishing (SMS phishing) is when attackers send fraudulent text messages to trick you into revealing sensitive information, clicking malicious links, or sending money. These texts often impersonate trusted organizations like banks, delivery services, government agencies, or even people you know.

Common SMSishing Attacks
Fake Bank Fraud Alerts
The Message: "FRAUD ALERT: Unauthorized charge of $1,247.99 detected on your account. Reply YES to approve or NO to block. Call 1-888-XXX-XXXX immediately."
How It Works:
- The text creates panic with a large unauthorized charge
- If you call the number, scammers pretend to be fraud prevention and ask for your card details, PIN, or online banking password
- If you click a link, it takes you to a fake bank website that steals your login credentials
- Some versions ask you to reply with personal information or account numbers
Fake Package Delivery
The Message: "USPS: Your package is on hold due to incomplete address. Update delivery info: [malicious link]" or "FedEx: Package couldn't be delivered. Reschedule here: [link]"
How It Works:
- Scammers know everyone gets packages, so this message feels relevant
- The link takes you to a fake USPS/FedEx/UPS website
- They ask for "redelivery fees" (stealing your credit card) or personal information
- Some versions install malware on your phone when you click the link
Fake Payment App Requests
The Message: "Venmo: Someone requested $500 from you. Click here to approve or deny: [link]" or "Zelle payment failed. Verify your account to complete transfer: [link]"
How It Works:
- The link takes you to a fake Venmo/Zelle/Cash App login page
- When you enter your credentials, scammers steal them and access your real account
- They immediately drain your balance and connected bank account
- Some variants claim you received money and need to "verify" to collect it
Fake Government/IRS Messages
The Message: "IRS: You have unclaimed tax refund of $2,847. Claim now before it expires: [link]" or "SSA: Your Social Security benefits are suspended. Verify your SSN immediately: [link]"
How It Works:
- Scammers offer "refunds" or threaten "suspensions" to create urgency
- Links lead to fake government websites stealing your Social Security number, bank account, or identity documents
- Some ask for payment to "process" refunds or "unsuspend" accounts
- They may also threaten arrest or legal action to pressure you
Fake Account Security Alerts
The Message: "Amazon: Suspicious activity detected on your account. Verify your identity to prevent suspension: [link]" or "Apple: Your iCloud account has been locked. Restore access: [link]"
How It Works:
- Fear of losing account access makes people click without thinking
- Fake login pages steal your username, password, and sometimes credit card stored in the account
- Scammers use your credentials to make purchases or steal stored payment methods
- They may lock you out of your real account by changing the password
Friend/Family Impersonation
The Message: "Hey mom, this is my new number. My phone broke. Can you send me $500 for emergency car repair? Venmo me at..." or "Hi, this is your grandson. I'm in jail and need bail money. Please don't tell mom."
How It Works:
- Scammers research your social media to learn family relationships and names
- They create urgency ("emergency", "in jail", "stranded") to bypass your skepticism
- They ask for payment via methods that can't be reversed (wire transfer, gift cards, crypto)
- They may claim they can't talk ("in court", "phone broken") to avoid voice verification
How to Protect Yourself from SMSishing
Defense Strategies
- Never click links in unsolicited texts: If you get an unexpected text from a bank, delivery service, or company, don't click the link. Go directly to their website (type it yourself) or use their official app.
- Don't reply to suspicious texts: Replying confirms your number is active, leading to more scam attempts. Just delete the message.
- Verify independently: If a text claims to be from your bank or a company, call them using the phone number on your card, statement, or their official website - not the number in the text.
- Check sender details: Legitimate companies use short codes (5-6 digit numbers) or consistent sender names. Random phone numbers or generic sender names are red flags.
- Look for urgency tactics: Scammers create panic ("account suspended", "unauthorized charge", "immediate action required"). Legitimate companies don't pressure you via text.
- Inspect links carefully: Before clicking, long-press (mobile) or hover (desktop) to preview the URL. Fake sites use similar domains like "usps-tracking.com" instead of "usps.com" or "amazonsecurity.com" instead of "amazon.com"
- Enable spam filtering: Most carriers offer free spam text filtering. Enable it in your phone settings or contact your carrier.
- Use two-factor authentication (2FA): Even if scammers get your password from a phishing text, 2FA adds another layer of protection. Use authenticator apps or hardware keys, not SMS codes.
- Trust your instincts: If something feels off, it probably is. Take a moment to think before acting on any text message request.
- Report and block: Forward spam texts to 7726 (SPAM) on most carriers. This helps them block future scam messages. Then block the sender.
If You Clicked a SMSishing Link
If you accidentally clicked a link or entered information on a suspicious site:
- Change passwords immediately: Update passwords for the affected account and any other accounts using the same password. Use unique passwords everywhere.
- Enable 2FA: Add two-factor authentication to all important accounts if you haven't already.
- Contact your bank: If you entered credit card or banking information, call your bank immediately to report potential fraud and monitor for unauthorized charges.
- Monitor your accounts: Check bank statements, credit reports, and account activity regularly for suspicious activity.
- Run antivirus scan: If you clicked a link on your computer or phone, run a full antivirus scan to check for malware.
- Report it: Report the scam to the FTC at ReportFraud.ftc.gov and forward the text to 7726 (SPAM).
Remember
When in doubt, don't click. Delete the text and contact the company directly through official channels you trust. Taking 2 minutes to verify can save you thousands in stolen money and months of identity theft recovery.
