Article first time published onIs Mirai a worm?
At its core, Mirai is a self-propagating worm, that is, it’s a malicious program that replicates itself by finding, attacking and infecting vulnerable IoT devices. It is also considered a botnet because the infected devices are controlled via a central set of command and control (C&C) servers.
How does a botnet work?
A botnet is a form of malware that involves an inter-connected network of hacked computers that lead back to a centralized computer controlled by a cyber criminal, who can then easily deploy cyber attacks to the entire network.

What is the vulnerability of IoT?
Security vulnerabilities in millions of Internet of Things devices (IoT) could allow cyber criminals to knock devices offline or take control of them remotely, in attacks that could be exploited to gain wider access to affected networks.
Which are reasons that Internet of Things devices are vulnerable to being part of a botnet?
Botnets rely on a large network of devices to complete their objective, making IoT — with its large attack surface — a prime target. Today’s cheap, internet-capable devices are vulnerable to botnet attacks, not only because of their proliferation, but because they often have limited security features.
What can an attacker do with a botnet?
