5 Types of Cyber Attacks That you are Likely to face in 2021

Cyber attacks and their after-effects are considered one of the global risks. There are several types of cyberattacks that individuals and organizations can face. The attacks can be classified into –

  • Attacks that target to gain access to confidential data
  • Attacks that disable operations

COVID-19 pandemic has created something new to play for hackers. In response, many organizations have made their IT strategies flexible to protect their IT assets.  Most of the cyber attacks rely on techniques like – infiltrating the IT system, gaining unauthorized access, weakening the network and so on.


To help your business prepared for the cyber attacks in 2021, we have identified the top 5 cyber security threats. In this post, we will you will know about some of the biggest cyber threats and how to equip your business with proper cyber security for 2021.


Before we get into details, let’s know a few things about the cyber attack.


What is a Cyber attack?


Cyber attacks are the assaults launched by cyber criminals using one or multiple devices against a single computer or network of computers. It will maliciously disable computers, steal data, and cause severe harm to the data. Most of the attacks intend to disable the computer system while others are intended to take control of the system.


It is important to know that cyber attacks can launch any kind of malicious program that attempts to damage, destroy or gain access to computer systems.


5 types of cyber attacks


Organizations incur severe financial losses, reputation damage, lose customers and face many difficult situations due to cyber attacks. To curb cyber attacks, organizations need a strong cyber security policy that safeguards the network and computer systems from unauthorized digital access.


There are different types of cyber attacks that are a serious threat to your organization. Let’s start with the top cyber attacks on our list –


1.    Phishing


Phishing is one of the common types of cyber attacks that uses disguised email, text or phone calls as weapons. The goal is to trick the target into believing that the message is something they want. For instance – a notice from a credit card company asking the recipient to take any action to unblock their card. It is one of the widespread and pernicious attacks that are increasingly becoming sophisticated.


Nearly, one-third of data breaches in 2020 involved phishing. Crisis such as the covid-19 pandemic gave cyber criminals a big opportunity to lure victims into taking their phishing bait.  You can implement proactive measures to protect your organization.


2.    Malware attack


A malware attack is something when cyber criminals implant malicious programs or software on someone else’s device without their knowledge. The most common types of malware are – viruses, spyware, Trojan horse, ransomware etc.


Malware attacks can occur on all types of devices, regardless of their level of protection. It is difficult to detect and typically infect the user’s devices without their knowledge. Software updates are very important to fix or remove computer bugs. Run system scan or software updates on a regular basis.

3.    SQL Injection


SQL Injection is another kind of cyber attack that can run arbitrary commands against your database. A successful SQL injection attack can read confidential and sensitive information from the database, modify the database, administer operations on the database and do a lot more.


SQL queries are used to execute commands such as updates, data retrieval, record removal etc. The attackers use this method to access the back-end data and damage the reputation of the company.


4.    Middle-man-Attack


MITM is a form of cyber eavesdropping in which the cyber criminals join the conversation between two parties and interpret the data through a compromised system. In many cases, organizations are unaware of the attack until data has been tampered with.


The Middle-Man-Attack can be executed in several ways that exploit the communications between other parties. Some of the MITM Attacks include – session hijacking, Wi-Fi eavesdropping, DNS spoofing, IP spoofing etc. This type of attack can be for financial gain or espionage,


5.    DNS tunneling


DNS tunneling is one of the difficult to detect cyber attacks that route the DNS requests to the attacker’s server. To establish a DNS tunnel, the attackers register a domain and setups a C&C server to send DNS query for a subdomain that represents encoded communication.


This cyber attack takes advantage of the fact that by using DNS requests to implement a command for the malware. The DNS is a flexible protocol and makes it possible for even unsophisticated attackers to use DNS tunneling technique to sneak data past the network security solutions.




There is an entire industry of cyber security that is focusing on adapting security practices to prevent cyber attacks. Businesses need to protect all their workloads, data and applications across multiple domains. They need integrated solutions to automate system monitoring, endpoint protection, vulnerability assessment and more to stop emerging threats.
