The suspicious text message

Dennis received a text from a friend that was unusually brief and out of character, simply asking, “Would you like to chat?” This raised immediate concerns, especially since the number appeared to be his friend’s but wasn’t recognized by Messenger as being in his contact list. Such scenarios often suggest phone number spoofing or hacking, where cybercriminals disguise their identity by using someone else’s number.

Signs your friend’s phone number might be compromised

Understanding the signs of a compromised phone number is crucial for protecting your personal information and that of your friends. Here are some indicators that your friend’s number might be hacked:

Unusual messages: If your friend starts sending texts that seem out of character – such as odd phrasing, unexpected links or requests for personal information – it could indicate their number has been hacked.

Unknown contacts: If Messenger says the number is not in your contact list when it actually is, it might indicate a problem.

Unexpected phone behavior: If your friend mentions their phone is acting strangely, they should look out for:

• High data usage: Unexplained spikes in your friend’s data usage can indicate malicious apps running in the background on their phone.
• Unfamiliar apps: If your friend notices new apps that they didn’t download, it could be a sign that their phone has been hacked.
• Battery drain: Rapid battery drain, even when not using the phone heavily, might suggest background malware activity.
• Slow performance: If your friend’s phone suddenly becomes sluggish or unresponsive, it might be due to malicious software using up the device’s resources.
• Pop-ups and ads: An increase in pop-up ads or redirects to dubious websites while your friend is browsing could indicate adware or malware on their device.

Unauthorized charges: If your friend’s phone bill shows unexpected charges, it can result from premium SMS services or calls made by malicious apps.

Spam sent from your friend’s number: If you or other contacts receive spam or suspicious messages from your friend’s number, it’s a strong sign that their phone might be compromised.

Steps to protect yourself

If you suspect your friend’s phone number has been hacked, consider these actions:

1) Verify with your friend: Contact them through another method to confirm if they sent the message.

2) Check for malware using strong antivirus software: Advise your friend to use strong antivirus software to scan for malicious apps or malware on the device. The best way for them to safeguard from malicious links that install malware, potentially accessing their private information, is to have antivirus software installed on all their devices. This protection can also alert them to phishing emails and ransomware scams, keeping their personal information and digital assets safe. Get my picks for the best 2024 antivirus protection winners for your Windows, Mac, Android and iOS devices.

3) Change passwords: If your friend suspects their phone number has been hacked, they should change their passwords for all accounts linked to their phone number. They should consider using a password manager to generate and store complex passwords.

4) Contact service provider: Your friend should contact their mobile service provider to report the issue. The provider can help secure their account and prevent further unauthorized access.

5) Enable two-factor authentication: Encourage your friend to enable two-factor authentication nn their accounts for added security.

6) Monitor accounts: Advise your friend to regularly check their bank statements and credit reports for suspicious activity.
