No, you cannot get hacked by replying to a scam text. However, you can get hacked if you click on a malicious link within a message or reveal sensitive information. Scam texts, or smishing, are fraudulent messages sent by scammers to trick you into sharing personal information or clicking on malicious links. These texts often mimic communications from legitimate companies, government agencies or even people you know to create a sense of urgency and prompt a quick reaction. Just because replying doesn’t directly install malware or hack your phone doesn’t mean it’s safe to do so.
Continue reading to learn what happens if you respond to a scammer, how to recognize a scam text and what to do if you fall for one.
What happens if you text a scammer back?
Replying to a scam text may not directly hack your phone, but it can still put your privacy and safety at risk. Here’s what could happen if you respond to a scammer:
- You confirm your phone number is active: When you reply to a scam text, you prove to the scammer that your phone number is valid and active. This confirmation makes you more of a target, and your phone number might be added to lists that are sold to other scammers.
- You may start getting more scam messages: Once scammers learn that your phone number is active, you may receive more spam texts, scam calls or even phishing emails. Engaging only once with a scammer can lead to an influx of unwanted and potentially harmful messages.
- You risk financial loss and identity theft: Although replying to a text message won’t directly hack your phone, it can lead to conversations designed to manipulate you into sharing personal details, like your Social Security number (SSN) or bank account information. If you share this information with a scammer, you could become a victim of fraud or identity theft.
- Your phone could become infected with malware: Texting back alone doesn’t install malware on your phone, but scammers may send a message containing a malicious link or attachment. If you click on either, your phone could become infected with various types of malware, such as spyware or ransomware.
How to spot a scam text message
Scam texts are created with the intention of tricking you into revealing sensitive information that scammers can use to hack into your accounts or commit identity theft. Knowing how to recognize a fake text message is the first step to protecting yourself from security risks. Here are the six most common signs of a scam text:
The text comes from an unknown number
If you receive a text message from a phone number you don’t recognize, or it appears to be from someone you know but the conversation history is missing, it could be SMS spoofing. This happens when scammers fake a sender ID to trick you into trusting the message.
The message creates a sense of urgency
Scam texts pressure you to act quickly, claiming that your account has been locked or that suspicious activity has been detected. These tactics are designed to make you panic and click on malicious links before you have time to think.
The message contains a suspicious link
If the message urges you to click on a link, especially one that looks misspelled or shortened (like bit.ly), be very careful. Suspicious links often lead to spoofed websites or can trigger malware downloads when clicked.
The sender offers something too good to be true
When the sender claims you’ve won a free prize, received a large amount of money or qualified for a limited-time deal, the text is almost always a scam. Before responding or clicking anything, consider whether you ever signed up for a giveaway in the first place. If you didn’t, the message isn’t real.
The message contains spelling or grammar mistakes
Messages from legitimate companies go through extensive proofreading before being sent out. If you receive a message that has awkward language or typos, this is a sign that it wasn’t sent from a trustworthy source.
The sender asks for sensitive information
No legitimate company will ask for your SSN, credit card number or online account credentials through text. If you get a message asking for personal or financial information, it’s likely a scam.
Common scam text messages
Scammers often use believable situations to deceive you into sharing personal information or clicking on malicious links. Here are five common text message scams to watch out for:
- Suspicious account activity alerts: If you get a warning about suspicious activity on your account with a link to secure it, don’t click on it. Instead, visit the company’s official website or app directly.
- Fake invoice or payment confirmation: If you receive a text thanking you for a payment you know you didn’t make, with a link to view the invoice, ignore the message. Always check your bank account or card statements first to see if there’s been a charge.
- Fake package delivery notifications: A text claiming there’s an issue with a delivery is likely a scam. Instead of clicking the link in the message, use the original tracking number from your order confirmation email to verify the shipment directly with the retailer.
- “You’ve won!” prize messages: If a message claims you won a free vacation, electronics or money but you never entered a contest, it’s a scam. Never click on links or share your personal information to “claim” the fake prize.
- IRS or government agency threats: Scammers may impersonate the IRS or other government agencies, claiming you owe money or will face legal action. Remember that the IRS never contacts people via text, so don’t interact with these kinds of messages.
What to do if you fall for a scam text
If you accidentally click on a link in a scam text, act quickly by following these steps:
Don’t enter any sensitive information
If the link leads to a website asking you to log in or enter your personal information, close the tab immediately. These fake websites are designed to steal your login credentials, financial details and sensitive data.
Run an antivirus scan
Clicking on some scam links may trigger a malware download on your phone. Make sure to install trusted antivirus software, like Avast Mobile Security or AVG AntiVirus, and run a full scan to identify and remove any threats.
Change your passwords immediately
If you already entered your login credentials on a suspicious link from a scam text, change the password for that account right away — and for any other accounts where you may have reused that password. Consider using a password generator to create strong, unique passwords for each of your accounts, and store them in a password manager like Keeper®.
Enable Multi-Factor Authentication (MFA)
Turn on MFA for all of your important accounts, including your bank, email and social media accounts. MFA adds an additional layer of security, requiring a second verification step to log in. With MFA enabled, even if a hacker has your username and password, they still won’t be able to access your account.
Check your bank and credit card statements
Review your recent transactions carefully for unauthorized charges, especially if you entered financial information after clicking on a suspicious link. If you spot anything unfamiliar, report the fraudulent activity to your bank or card issuer immediately, and consider placing a credit freeze to be safe.
Monitor your online accounts for unusual activity
Watch out for unrecognized login attempts, password reset requests or changes to your account settings. If you don’t recognize any of the activity, it may be a sign that someone is trying to gain access to your account using information you provided through the malicious link.
Report the scam text
To help mobile carriers track and block scam numbers, report the text by forwarding it to 7726 (SPAM). You can also report the text to the Federal Trade Commission (FTC) and to the company the scammer is impersonating.
Stay safe from scam texts
Scam texts are growing more common as scammers constantly find new ways to trick people into clicking on malicious links. By staying alert, especially when receiving messages from unknown numbers, you can avoid falling victim to these scams.
Frequently asked questions
Can someone hack your phone through a phone number?
No, someone cannot directly hack your phone just by knowing your phone number. However, a scammer can use your number to launch phishing scams, send spam texts or conduct SIM swapping. These tactics aim to trick you into revealing personal information or giving scammers control of your phone number. To stay safe, avoid clicking on suspicious links, enable MFA on your accounts and set up a PIN with your mobile carrier to prevent unauthorized SIM swaps.
Is it safe to reply to unknown text messages?
No, it is generally not safe to reply to unknown text messages. Responding confirms that your phone number is active, making you a target for more spam or scams. Even a simple reply like “Stop” can tell scammers you are actively using your phone. Instead of responding, delete the message, report it and block the number. If the message seems legitimate but unexpected, contact the company or person through official channels to verify it.
What should I do if a stranger texts me?
If you receive a text from someone you don’t know, be cautious and don’t respond right away. Scammers sometimes pose as wrong numbers or casual contacts to start a conversation. If they include a link in the message, don’t click on it, as unfamiliar links can lead to phishing attacks or malware infections. Look for poor grammar, urgent requests or offers that seem too good to be true — those are signs the message is a scam.
If the text turns out to be from someone you know using a new phone number, they’ll likely identify themselves another way. When in doubt, don’t engage with the stranger.
