Top 10 Signs Your Device Has Been Hacked & What to Do
Introduction
With cyber threats increasing every year, it’s crucial to recognize the signs of a hacked device. Hackers use malware, phishing scams, and other tactics to steal data, spy on users, or take control of devices. If you suspect your device has been compromised, identifying the problem early can help prevent further damage. Here are the top 10 signs your device has been hacked and what you can do about it.

1. Unusual Battery Drain
If your phone or laptop battery suddenly drains much faster than usual, it could indicate malware running in the background.
What to Do:
- Check battery usage settings to identify suspicious apps.
- Uninstall unknown apps or software.
2. Slow Performance
A sudden decrease in speed or lagging performance may mean your device is infected with malware or spyware.
What to Do:
- Run a full system scan with a trusted antivirus program.
- Clear cache and uninstall untrusted applications.
3. High Data Usage
If your internet usage is unusually high without a clear reason, a hacker may be transmitting stolen data.
What to Do:
- Monitor data usage in device settings.
- Disable unknown apps that are consuming excessive data.
4. Frequent Pop-ups & Ads
Excessive pop-ups, especially those redirecting you to unknown websites, are a red flag for malware infection.
What to Do:
- Avoid clicking on suspicious links.
- Use an ad blocker and scan your device for malware.
5. Unknown Apps or Programs Installed
If you notice software or apps you didn’t install, your device may have been compromised.
What to Do:
- Uninstall unfamiliar applications.
- Change your device passwords and enable two-factor authentication (2FA).
6. Unauthorized Transactions or Messages
If you see transactions or messages that you didn’t authorize, your accounts may be hacked.
What to Do:
- Contact your bank and change financial account passwords immediately.
- Enable transaction notifications for real-time alerts.
7. Overheating Device
Hacked devices often overheat due to malware consuming system resources.
What to Do:
- Check running applications and stop unnecessary background processes.
- Restart your device and update security patches.
8. Your Contacts Report Strange Messages from You
If your friends or colleagues receive messages or emails from you that you didn’t send, your account may be compromised.
What to Do:
- Change your email and social media passwords immediately.
- Enable two-factor authentication on all accounts.
9. Webcam or Microphone Turns On Unexpectedly
If your webcam light turns on by itself, or you hear strange noises from your microphone, hackers might be spying on you.
What to Do:
- Cover your webcam when not in use.
- Check app permissions and disable microphone and camera access for suspicious apps.
10. Your Antivirus or Security Software is Disabled
If your security software is turned off without your permission, malware may be trying to prevent detection.
What to Do:
- Manually reinstall and run a security scan.
- Boot your device in safe mode and remove unauthorized applications.
How to Protect Your Device from Hackers
- Use Strong Passwords: Create complex passwords and update them regularly.
- Enable Two-Factor Authentication (2FA): Adds an extra layer of security.
- Install a Reliable Antivirus Program: Regular scans help detect malware early.
- Keep Software Updated: Updates fix security vulnerabilities.
- Avoid Public Wi-Fi: Use a VPN when connecting to unsecured networks.
- Be Cautious with Emails & Links: Phishing attacks trick users into giving away credentials.
