The range of destruction of these types of the virus actually varied. Some may cause a mild dismantling effect while others may demolish your hardware, software, & files. This malicious code remains dormant until someone consciously or unconsciously activates it, spreading the infection without the valid approval of the user or system administration.


Most commonly, people spread computer viruses most unknowingly by sending emails with viruses as attachments or sharing infecting files. It can also disseminate through social media scam links & internet file downloads.


A computer worm is a self-sufficient type of malware that can proliferate & activate without human assistance. The fundamental difference between a virus & a worm is that virus is usually propagated by their host while worm has a self-replicating power that spread independently once they have breached the system.


Normally computer worms transmit by exploiting operating system vulnerabilities. Worms create similar destruction like viruses, few are given below:


  • Corrupt & delete files
  • Stealing of confidential information
  • Consume bandwidth
  • Overloaded networks
  • Spread malware like spyware or ransomware
  • Deplete hard drive space
  • Install a backdoor

Ransomware is a type of malicious software that utilizes encryption to hold a hostage of victims’ information at ransom. Cybercriminals use ransomware as extortion software by locking access to your computer system.


They intimidate the victim that they will not release access until receive any ransom fee. Due to this malware attack, the victim is unable to access their files, databases & applications since their critical data is encrypted. Cybercriminals often aim to spread ransomware across a network, database & fileservers, so that the function of an entire organization is disrupted.


Typically ransomware circulates through phishing emails, infected malicious software apps, spam, infected external storage devices & compromised websites.


Either small or large, a business that became the victim of a ransomware attack can experience huge financial loss in terms of productivity & data loss. Not only that, if the victim is unable to pay the ransom amount within the deadline then hackers may expose important customer data in public. Due to this privacy breach, an organization might face legal consequences & loss of brand trust.

A botnet is a combination of Internet-connected devices, including PCs, servers, mobile devices & IoT devices that are contaminated with this malware & controlled remotely by a single attacking party which is known as “bot-harder”. Another name of the botnet is “robort network”. 


The controller of a botnet can run the commands of these compromised computers through communication channels made by standards-based network protocols, such as IRC & Hypertext Transfer Protocol.


Most commonly hackers are looking for a security vulnerability in a network so that they can expose the entire system unknowingly with a malware infection. They spread the malware through emails or other online messages.


Once the botnet takes control of each computer, they can below admin-level access to monitor:

  • Collecting the user’s data
  • Reading, analyzing & writing system data
  • Monitoring the user’s activities
  • Exchanging files & other data.
  • Installing & operating any applications
  • Looking for vulnerabilities in other devices.

Cybercriminals develop botnets mainly to gain some illicit objectives. Through botnet, the attackers mainly perform identity theft, confidential information theft, cryptocurrency scams, or selling accesses to other criminals. 


To stop this emerging security threat, we’re offering some suggestions for you:

  • Train users not to engage in any suspicious activity that traps them a risk of bot infections or other malware contamination. They should be careful downloading attachments or links, opening emails or messages from untrusted sources.
  • The Central IT team should monitor the performance of the network to identify any irregular behavior.
  • Regular update your operating system & all software applications.
