What is a Botnet?

What is a Botnet & How to prevent your PC from being enslaved?

Has your computer been acting weird lately?
Running slower than usual, to the point of crawling like a boa constrictor after lunch?
Any inexplicable error messages, popping out randomly?
Or your fan going into overdrive out of nowhere, even though your PC is supposed to be idle?

Not that we want to alarm you, but there’s a slight possibility that your computer was turned into a zombie.

What is a Botnet?

The term “botnet” comes from combining the words “robot” and “network”. Botnets are entire networks of computers controlled and instructed to do a bunch of things, such as:

– attack other computers
– send spam or phishing emails
– deliver ransomware
– spyware or many other similar malicious acts

As you are aware, a single piece of malware can cause enormous damage. Now imagine what an army of millions of computers can do through coordinated attacks. Even small botnets can affect a business.

What abilities do Botnets have?

– Send out spam emails – if a spammer has access to a botnet, it’s very cost effective and it will cost them close to nothing to do this
– Launch a Distributed Denial of Service Attack (DDoS) on a website, company, government etc
– Commit advertising fraud: Computers all around the world can generate fake clicks on ads
– Keep phishing websites active and frequently change their domains to remain anonymous and undetected by law enforcement
– Distribute malware, ransomware or spyware. Besides the direct financial damage incurred, this can also expand the botnet further

How to prevent your computer from becoming part of a botnet?

1. Don’t click on any suspicious links that you’re not sure / don’t know where they lead.
2. Do not download any attachments that you never requested.
3. You need a good antivirus and antispyware software, installed from a reputable source.
4. If you already have antivirus and antispyware software, check to see if they are activated, patched and up-to-date.
5. Also make sure that your firewall is on.
6. Keep all your software up to date, especially your browser, Adobe Flash, Adobe Reader and Java.
