![]() Botnet attacks are akin to having a threat actor working within the network, as opposed to a piece of self-replicating malware. Unlike other malware that replicates itself within a single machine or system, botnets pose a greater threat because they let a threat actor perform a large number of actions at the same time. It turns compromised devices into ‘zombie bots’ for a botnet controller. A botnet attack is a large-scale cyber attack carried out by malware-infected devices which are controlled remotely. Attackers can control botnets remotely and receive software updates from them, using those updates to quickly shift their behavior. A botnet’s strength is in the number of infected machines it contains. The botnet command and control model allows the attacker(s) to take over operations of these devices in order to control them remotely. Attackers use these compromised devices to launch large-scale attacks to disrupt services, steal credentials and gain unauthorized access to critical systems. What is a botnet attack, and how do you stop one?
