10 Warning Signs Your Device Has Been Hacked

In today’s digital world, our devices hold sensitive personal and professional information, making them attractive targets for hackers. Often, signs of a compromised device are subtle and can go unnoticed until the damage is done. Being able to recognize these signs early is key to protecting your data and mitigating risks. Here are ten common warning signs that your device may have been hacked and what you should do if you suspect a breach.

1. Unusually Slow Performance

If your device suddenly becomes slow or lags frequently, it could be running malicious software (malware) in the background. Malware often consumes resources like RAM and CPU, leading to noticeable slowdowns.

What to Do:

• Check the Task Manager (Windows) or Activity Monitor (Mac) for suspicious processes.

• Run a full antivirus scan.

2. Unfamiliar Apps or Programs

Have you noticed apps or software installed that you don’t recognize? Hackers sometimes install malicious programs to steal data or control your device remotely.

What to Do:

• Uninstall unknown apps immediately.

• Research the app’s name to determine if it’s harmful.

• Use anti-malware tools to scan for hidden programs.

3. Frequent Pop-ups and Ads

Unexpected pop-ups, especially those that urge you to click on links or download files, are a red flag. These are often signs of adware or spyware infections.

What to Do:

• Avoid clicking on any suspicious pop-ups.

• Clear your browser cache and reset it to default settings.

• Install a reliable ad-blocker.

4. High Data Usage

A sudden spike in data usage could indicate that malware is sending information from your device to a hacker’s server.

What to Do:

• Monitor your data usage through your device’s settings or your internet provider’s dashboard.

• Disconnect your device from the internet and investigate.

5. Your Passwords Stop Working

If you can’t log into accounts using your usual passwords, it may mean someone has taken control of them.

What to Do:

• Use the account recovery options to regain access.

• Change your passwords immediately, starting with your email account.

• Enable two-factor authentication (2FA) on all important accounts.

6. Friends Report Strange Messages from You

If your friends or colleagues receive emails or messages you didn’t send, your device or account may have been hacked. Hackers use this tactic to spread malware or phishing links.

What to Do:

• Inform your contacts not to click on any suspicious links.

• Change your account passwords and check for unauthorized activity.

• Run an antivirus scan on your device.

7. Unauthorized Purchases or Financial Activity

Unexplained charges on your accounts or emails about purchases you didn’t make are clear indicators that someone has accessed your financial information.

What to Do:

• Contact your bank or credit card provider immediately.

• Monitor all your financial accounts for further unauthorized activity.

• Update passwords for financial accounts and enable 2FA.

8. Your Device Overheats or Battery Drains Quickly

A hacked device might be running malicious programs in the background, causing it to overheat or experience a rapid battery drain.

What to Do:

• Check which apps are consuming the most battery or CPU.

• Disable or uninstall suspicious apps.

9. Your Homepage or Search Engine Has Changed

If your browser’s homepage or default search engine has been altered without your permission, it’s likely a sign of browser hijacking malware.

What to Do:

• Reset your browser to its default settings.

• Remove any unknown browser extensions or plugins.

• Run anti-malware software to check for infections.

10. You Notice Suspicious Network Activity

A compromised device might frequently connect to unknown websites or servers. You may notice unusual traffic when monitoring your network.

What to Do:

• Check your router logs for suspicious connections.

• Disconnect your device from the network.

• Run a security scan to identify the issue.

What to Do If You Suspect a Hack

If you suspect your device has been hacked, take immediate action:

1. Disconnect from the Internet: This stops the hacker from continuing to access your device.

2. Run a Security Scan: Use reputable antivirus or anti-malware software to identify and remove threats.

3. Change Your Passwords: Start with critical accounts like email and banking. Use unique, strong passwords.

4. Check for Updates: Ensure your operating system and apps are up-to-date to close any vulnerabilities.

5. Consult an Expert: If the issue persists, contact a trusted IT professional like Sergeant Solutions for assistance.
