Botnets Explained: Is Your Computer Part of a Zombie Army?

The Zombie Army

Your computer might be working for a criminal right now, and you wouldn't even know it. A botnet is a collection of internet-connected devices (PCs, servers, IoT devices) that have been infected and are controlled by a common attacker.

What Do Botnets Do?

Individually, an infected device (a "bot") isn't very powerful. But together, thousands of bots can cause massive damage:

1. DDoS Attacks: Flooding a website with traffic to knock it offline.
2. Spam Campaigns: Sending millions of phishing emails.
3. Credential Cracking: Trying stolen passwords on Netflix, banking, or gaming sites.

How Devices Get Recruited

• Weak Passwords: IoT devices (like smart cameras) often have default passwords like admin/admin. Bots scan the web for these.
• Unpatched Software: Exploiting security holes in your browser or OS.
• Malware: Downloading a "free game" that includes a botnet installer.

Signs You Are Infected

• Slow Internet: Your bandwidth is being used to attack others.
• High Fan Speed: Your processor is working hard even when you aren't doing anything.
• Strange Pop-ups: Unexpected ads or messages.

How to Check and Clean

1. Check Your IP: Use our IP Reputation Tool to see if your public IP address has been flagged for spam or botnet activity.
2. Update Everything: Keep your OS and antivirus updated.
3. Reboot: Some IoT malware lives in memory. A simple restart can sometimes clear it (though changing the password is required to stop reinfection).

Don't let your device be a pawn in a cyber war. Secure your devices and monitor your network reputation.
