Most often, criminals are infected by thousands of devices and combine them into a single network – a botnet, or “bot network”.

Creating a botnet – it’s just a first stage of criminals evil plan. After the infected device is formed by a powerful infrastructure it can be used to attack everyone on the network. There are four main areas where the owners of botnets and their puppets can act.


Probably the most famous way to use such networks – Distributed Denial of Service attacs. DDoS-attack of botnet generates a lot of requests to the target server, which no server can really handle while ordinary users can’t use the server because of its overload.

These attacks, despite their primitive nature, are still a main weapon of hackers. Their relevance will only grow with the increasing number of Internet-connected gadgets. The fact that for DDoS-attacks can be used literary any device with Internet connection, even the most primitive devices such as surveillance cameras or appliances.

You can really laugh over WI-FI-kettles and refrigerators, but the era of Internet of Things has already come: Now IoT-device number in the hundreds of millions, and in the future will account for billions.
