What to Do If Your Kid’s Phone Is Hacked: A Parent’s Step-by-Step Guide

Finding out your child’s phone has been hacked is a stressful experience. Phones store so much of their personal life—photos, messages, social media, and even financial information. The thought of someone accessing or misusing this is understandably unsettling.

If it happens to you, you can take steps to secure their device, protect their privacy, and prevent future issues.

Signs That Your Child’s Phone Might Be Hacked

 

Children might not always notice when something is wrong with their phone—or they may not know how to tell you. Watch out for these signs that something might be off:

  • Apps you don’t recognize: New apps appear that your child didn’t download.
  • Annoying pop-ups: Frequent ads or redirects to unfamiliar websites.
  • Strange messages: Their friends get odd or inappropriate messages from your child’s accounts.
  • Unusual data usage: A sudden spike in data consumption.
  • Battery drains quickly: The phone’s battery runs out much faster than usual.
  • Slow or glitchy phone: The device is sluggish, freezes, or behaves erratically.
  • Account changes: Passwords or security settings are altered without their knowledge.

 

If you notice any of these, act quickly to limit the damage and help secure their phone.

 

Steps to Take If Your Child’s Phone Is Hacked

 

  1. Stay Calm and Reassure Your Child

Let them know it’s not their fault and that you’ll work together to fix the problem. Ask if they’ve noticed anything strange, like weird messages, apps, or pop-ups.

2.      Disconnect the Phone from the Internet

Turn off Wi-Fi and mobile data to block further access. You can also enable Airplane Mode as a quick way to cut all connections.

3.      Look for Suspicious Apps or Files

Sit with your child and go through their apps and files. If you see apps they didn’t download or files they don’t recognize, delete them. Be cautious not to remove essential system apps—if you’re unsure, seek professional help.

4.      Change Passwords Immediately

Help your child reset the passwords for all accounts linked to their phone. Prioritize email, social media, and any other accounts they use frequently. Choose strong, unique passwords and turn on two-factor authentication wherever possible.

5.      Run a Malware or Security Scan

If the phone has antivirus software installed, run a full scan. If not, install Bitdefender Mobile Security for Android or iOS to check for malicious programs or files. Follow the app’s instructions to remove any threats.

6.      Update the Phone’s Software

Check that the operating system and apps are up to date. Updates often fix security flaws hackers can exploit.

7.      Notify Their Contacts

If the hacker accessed your child’s messaging or social media accounts, let their friends and contacts know. Warn them not to click on unusual links or respond to strange messages.

8.      Check for Financial Fraud

If your child uses payment apps or has saved payment details on their phone, check those accounts for any unauthorized activity. Report anything suspicious to the service provider immediately.

9.      Review App Permissions

Go into the phone’s settings and check which apps have access to sensitive information like the camera, microphone, or location. Revoke permissions for apps that don’t need them.

10.  Report the Incident

If the hacker has caused significant damage—like identity theft or financial fraud—report it to your phone provider and the authorities. Many companies have dedicated support teams for such situations.

11.  Talk About Online Safety

Take this as an opportunity to teach your child how to stay safe online. Talk about avoiding suspicious links, being cautious with personal information, and letting you know if something feels off.

12.  Perform a Factory Reset (if Necessary)

If the phone still shows signs of hacking after taking the steps above, a factory reset might be your best option. Back up important data first, as this process erases everything on the device.

13.  Monitor the Phone Regularly

Keep an eye on your child’s phone activity for a while to make sure everything is back to normal. Use Bitdefender Mobile Security to keep their device secure and activate Bitdefender Parental Control to monitor any suspicious activity on it.

14.  Establish Family Cybersecurity Habits

Encourage everyone in the family to use strong passwords, enable two-factor authentication, and stay alert to potential risks. Regularly talking about online safety as a family can help prevent future problems.
