How to avoid Botnet attacks

A botnet is an internet connected computer system or device which has been infected by a malware specialised in targeting computers through a backdoor exploit. Subsequently, the infected computer is used by an adversary, who has several other botnets to launch a group of botnets on a website in order to proliferate a denial of service attack.

Malware containing the ability to create botnets works covertly, avoiding system detection in a sophisticated manner to acclaim administrator privileges of the infected system. After gaining access to the system an adversary is able to issue commands to the device to coordinate and control a botnet attack, meanwhile the owner of the computer system will remain oblivious to what is happening because the infected system continues to operate normally for the user.


Although DDoS (Distributed Denial of Service) attacks are the most popular uses of botnets, other ways in which cybercriminals take advantage of botnets are by sending spam, recruiting other botnets and theft of data.


Email spam campaigns are assisted by botnets, using infected systems to send spam mail, which results in the recipients contact list being sent spam, continuing in an iterative process.


Certain, botnets have the capability of stealing passwords and credit card details, whereas other botnets have Trojans designed to spoof websites within the user’s browser to steal confidential data.
