A botnet is a network of computers infected with malicious software and remotely controlled by an attacker without the owners’ knowledge.
These infected computers, also called “bots” or “zombies,” can be used to carry out various criminal activities, such as:
Distributed Denial of Service (DDoS) attacks: Overloading websites with traffic to make them unavailable.
Spamming: Sending large amounts of junk mail.
Data theft: Stealing personal information or financial data.
Cracking encryption: Breaking into encrypted systems.
Botnets can consist of anything from a few hundred to several million machines and are often controlled through hidden commands on seemingly normal websites or via chat services.
Keep software updated: Botnets often exploit vulnerabilities in outdated software. By keeping operating systems, applications, and antivirus programs up to date, you reduce the risk of your device being infected.
Use strong passwords: Botnets can use brute force attacks to gain access to devices. Strong, unique passwords for all accounts and devices make it harder for attackers to succeed.
Enable firewall: A firewall can block unwanted traffic and prevent an infected device from communicating with botnet control servers, limiting the damage.
Install antivirus software: Reliable antivirus software can detect and remove malware used to recruit devices into botnets.
Be cautious with email attachments and links: Many botnets spread via phishing emails. By avoiding opening attachments or clicking on links from unknown senders, you can prevent infection.
Monitor network traffic: Network monitoring tools can detect unusual activity that may indicate a device is part of a botnet. Early detection can help isolate and remove the infection.
Educate users: Inform users about how botnets work and how they can protect themselves. Knowledge about the risks of suspicious downloads and sharing information online can prevent infection.
Several of Sicra’s partners have solutions to counteract botnets, including Arctic Wolf, F5, and Microsoft. We can help implement and follow up on these.
