7 Cybersecurity threats everyone needs to know

7 Cybersecurity threats everyone needs to know

Cybersecurity attacks, designed to disrupt, steal, modify, or disable information through unauthorized access to computer systems, pose an escalating threat globally. In 2023, India ranked among the top three nations with the highest server access and ransomware attacks.

Campaigns utilizing network-based ransomware worms, capable of autonomous execution without human intervention, are becoming prevalent, as highlighted in the Cisco Annual Cybersecurity Report. While economic destruction was a primary goal for attackers, a shift towards data destruction has emerged.

Here are the seven most common types of cyber-attacks:


Phishing involves fraudulent communications, often via emails, appearing to be from trustworthy sources. Attackers aim to extract sensitive information like financial or user-based data. Various forms include Spear Phishing, Vishing, Smishing, and Whaling.

2. Denial-of-Service (DOS):

DOS attacks aim to shut down a targeted computer or network, making it inaccessible. Distributed denial-of-service (DDoS) attacks involve multiple sources flooding the target. Recent DDoS attacks, like the 'Gargantuan botnet,' pose significant threats.

3. Password Attack:

Password hacking is a common method to gain unauthorized access to critical data. Attackers employ social engineering skills, test network connections, or simply guess passwords. Brute force and dictionary attacks are prevalent methods.

4. SQL Injection:

This attack involves injecting malicious code into a server using SQL, forcing it to reveal protected information. Prevention measures include input validation and parameterized queries.

5. Cross-site Scripting (XSS):

Attackers use malicious scripts through content on trustworthy websites, transmitted to a user's browser when interacting with clickable content. XSS attacks contribute to a significant percentage of data breaches in today's app-centric world.

6. Trojan Horses:

Similar to the ancient tale of the Trojan horse, malicious programs are hidden within disguised legitimate sites. Once downloaded or installed by unsuspecting users, these programs enable hackers to infiltrate and cause damage.

7. Man-in-the-Middle (MITM) Attack:

In an MITM attack, an attacker eavesdrops on communication between a user and an application, altering or accessing messages illicitly. Measures to counter MITM attacks include end-to-end encryption and the use of Virtual Private Networks (VPNs).

As cyber-attacks evolve in complexity, the demand for cybersecurity professionals continues to rise. The global cybersecurity job market faces over 3.5 million vacant positions, emphasizing the critical need for modern and secure solutions.
