What is a Botnet?
A botnet is a network of computers, servers, or IoT devices infected with malware, allowing an attacker to control them remotely. Botnets are often used to conduct cyberattacks, steal data, or send spam.
Common Uses of Botnets:
- DDoS attacks to overwhelm websites or services.
- Sending spam or phishing emails on a massive scale.
- Credential stuffing attacks to gain unauthorized account access.
- Cryptojacking, where the attacker uses infected devices to mine cryptocurrency.
Defending against botnets involves keeping devices updated, using antivirus software, monitoring network traffic, and implementing firewalls and WAFs.
Botnet activity is a major cybersecurity concern, as these networks can compromise thousands of devices and cause widespread damage.
