Top 9 Examples Of a Malicious Code

Malicious codes are not a new thing anymore, they have been hovering in the world of technology for almost 50 years! But what is malicious code? It is construction for destruction; a code designed to harm or hack a computer system. Since it is quite common, cyber awareness is important; you should know some examples of malicious code to save yourself from potential risks.

Cybercriminals gain access unlawfully through these codes. They take authority over the data and can do the following to it:

  • Steal information
  • Sell the stolen information
  • Encrypt it, rendering it useless

Top 9 Examples of Malicious Code

Let’s have a closer look at the kinds of malicious codes taking rounds.


It is software that allows malicious hackers to take remote control of the victim’s computer, along with all administrative privileges. Rootkits are easily put into applications, hypervisors, kernels, or firmware.

Their spread is easy via phishing, malicious downloads, malicious attachments as well as compromised shared drives.

Wiper Malware

Its sole purpose is to delete the user’s data and ensure that no recovery is possible. Wipers take down the computer networks. It does it in both public and private companies across sectors. Cybercriminals also use wipers to cover up their traces after an intrusion, which makes victims weak to respond.

Trojan Horses

It is an example of a malicious code that relies on social engineering. It has deceptive practices; therefore, the malware was named after the famous Trojan horse.

This code, unlike a self-replicating computer virus, requires the user to open an infected file on the device.

Computer Virus

It is a kind of malicious application that replicates itself by sending its code into other computer programs. Once the reproduction completes, targeted areas become infected.

Computer Worms

A computer worm malicious malware replicates itself and spreads to as many devices as it can, a phenomenon similar to that of a virus. That is why worms are thought to be a subtype of the virus.

Internet Bots

They are also referred to as web robots. Internet bots are software applications that run on automated scripts. Internet bots often perform simple and repetitive tasks like instant messages or crawling websites. Both gadgets, mobile as well as desktop devices, are its target.


It is a type of malicious software that spies on devices to gather sensitive information. This data is then forwarded to attack.

Ransom ware

Logic Bombs

It is a malicious string code intentionally injected into the software. Logic bombs are automatically set off after certain requirements are clicked.

Final Words

While all malicious codes such as viruses, rootkits, worms, or Trojans may be common examples of malicious codes, there are various others in the market as well. It is better to keep the IT department updated. If you need any help with cyber security, talk to professionals from Ranger’s Wi-Fi for help.
