Detecting and Preventing Home Computer Hacks

With more people working and studying from home, cybersecurity threats are more rampant than ever. One of the most alarming scenarios is when your home computer is hacked. Here, we'll discuss the common signs of a computer hack, how to detect an intruder, and steps to secure your home network.

Common Signs of a Hacked Computer

.detecting signs that your computer has been hacked can be crucial in protecting your data and privacy. Here are some indicators:

Computer Slows Down: If someone is using your computer, the processor may struggle to handle additional tasks, causing a noticeable slowdown in internet speed and application performance. Pop-ups and Fake Antivirus Messages: These can be a sign that your computer is already compromised. If you start seeing unexpected pop-ups or receive warnings about a fake antivirus, it's time to check for malware. Redirects and New Browser Bars: Unrecognized browser bars or websites you never visited suddenly appearing in your browsing history may indicate a malicious program at work. Malicious Pop-ups: Despite having a pop-up blocker enabled, if you still receive pop-ups from unfamiliar or untrusted sites, it's a strong indication of a possible hack. Unauthorized Mouse Clicks: If your mouse moves or clicks on its own, especially when you're not actively using the computer, it's a red flag. Antivirus Program Disabled: Unauthorized disabling of your antivirus or security software is a clear sign that your computer has been compromised. Email and Spam Reporting: If you receive emails reporting that your computer is sending spam, it's a sign that your computer is being used as part of a botnet attack, sending unsolicited emails to your contacts.

How to Detect a Hacker on Your WiFi Network

Even if the hacker is no longer connected to your LAN, they could still have accessed your home computer. Here's what you can do to spot them:

Port Forwarding: Look in your router’s settings under 'port forwarding'. By default, no ports are forwarded, but if a port is open, it could mean that a remote program is listening on that port.

Check Router For Unauthorized Activity: Use a tool like SpeedofWeb Router Check to see if anyone outside your LAN can access your home network.

Steps to Secure Your Home Network

To prevent future invasions, take the following steps:

Enable Guest Network: Use a guest network for visitors. They can access the internet but not your connected devices and data, making it harder to hack your home system. Use Strong, Unique Passwords: Ensure that your guest network uses a different and strong password than your main network to reduce the risk of unauthorized access. Regular Software Updates: Keep your operating system and security software up to date. Firewall Protection: Turn on the firewall within your router to add an extra layer of security. Monitor Network Activity: Regularly check your router and computer for unusual network activity, and use network monitoring tools to track and alert you to suspicious traffic.
