Botnet Attacks Explained in a Nutshell 

As per definition, a botnet may be a network of compromised or malicious computers that are often supervised by an impact channel. This control channel, often called the Bot herder or Botmaster, uses these botnet computers to launch attacks targeted to crash a target network and thus execute CPU-intensive tasks. 

These botnets are often composed of three broad components

  • Bots
  • Command-and-Control servers (C&C)
  • Botnet operator.

How are Botnets enhancing their scope?

Botnets are the foremost prevalent and one of the most crucial threats to the system and IoT security within the age of cloud computing. New pervasive computing architectures, like always-on mobile devices and Internet-of-Things (IoT), provide additional infection vectors for botnet attacks.

As the Internet of Things (IoT) evolves over the years, there's an increasing connection between our household devices. This suggests an enormous scope for potential botnet devices/attacks through these devices. These devices may include webcams, monitoring controls, toasters, and even refrigerators. Once a tool is infected with botnet malware, it is often used adversely to attach to its network connectivity to execute the attack altogether. 

What are the designated targets for Botnets?

Ideally, botnets may have various targets. Some of them being different sectors or groups in modern society, a natural conclusion given botnet capacity to mobilize great numbers. the following unordered list of targets are but a couple of the potential victims and sought out results of botnets:

  • Groups of political disparity of political critics, as discussed in Nazario paper
  • National power grids and essential service providers
  • Civilian people information and passwords
  • Espionage and intelligence gathering of foreign nations
  • Cracking encrypted or hashed data

Challenges with the spread of Botnets

The current state and scope of botnets are marginally evolving. One of the most common challenges is the continued spread of botnets anchored in pervasive computing devices. As devices that are allowed with computational headroom, the power of botnets to perform increasingly well to mask their existence grows.

The mitigation of those attacks may vary considerably, counting on the precise scenario and device in question. Some devices, like smartphones, are shown to be ripe for exploitation. An example is the app certification process, which is insufficient to stop malicious apps from stepping into various app stores. Furthermore, some Android device operating systems don't place strict limitations on installing apps through unauthorized sources or package repositories. This considerably complicates the method of avoiding botnet apps on mobile.

In all, the increasing complexity and scope of future botnet threats include encrypted communication, wherein they're expected to encrypt the bot binary with a personal key pair. 

Another major challenge that's still not entirely out yet is the evolution of social botnets. These botnets impersonate user behavior and cause spam rates to extend exponentially when taking care of social platforms. Hence, these give botnet developers an excellent scope to enhance their existing tools, technologies, and skillsets.

To avoid being caught during a botnet, you would like regular security awareness training programs to identify malicious links. A top-quality antivirus solution must be up so far to scan your network regularly. For more such information, be happy to get in tune with our experts at today.
