This comprehensive guide delves into cyberattack's nature, evolution, impacts, and intricacies, offering valuable insights into the modern digital threat landscape and the strategies needed to navigate it safely.

What is a Cyberattack?

A cyber attack is an attempt by individuals or organized groups to gain unauthorized access to computer systems or disrupt or disable them. These attacks often aim to steal sensitive data, launch other malicious activities, or cause chaos and disruption to information systems.

What are Types of Cybersecurity Attacks ?

Different types of cyber attacks

  1. Credential Stuffing: It is a cyber-attack where attackers use stolen account credentials (usernames and passwords) to gain unauthorized access to user accounts through large-scale automated login requests directed against a web application. The attack relies on many users reusing the same login credentials across multiple services. Once they gain access they can perform account takeovers.
  1. Eavesdropping Attacks: In these attacks, hackers intercept and capture transmitted data, often over unsecured networks. This attack is dangerous on public Wi-Fi networks, where attackers can access sensitive information like passwords and credit card details.
  1. AI-Powered Attacks: With the rise of artificial intelligence, there has been an increase in AI-powered cyber attacks. These involve using machine learning algorithms to predict user behaviour, create more convincing phishing emails, and automate attacks at a scale and sophistication previously impossible.
  1. Cryptojacking: An emerging cyber attack, cryptojacking is where hackers use a victim's computing resources to mine cryptocurrency without their consent. It often involves embedding a piece of JavaScript code into a website or an ad.
  1. Watering Hole Attacks: A watering hole attack targets a specific group by infecting websites they are known to visit. The goal is to infect a user's computer and gain access to the network at the user’s place of employment.
  1. Fileless Attacks: These attacks do not rely on files and leave no footprint, making them hard to detect and trace. They typically involve the exploitation of vulnerabilities in trusted programs or scripts already on the victim's computer.
  1. Insider Threats: These attacks involve individuals within the organization who use their inside knowledge of the organization's security practices, data, and computer systems to carry out the attack. An insider threat could be a current or former employee, a contractor, or a business associate.
  1. Supply Chain Attacks: These attacks target less secure elements in the supply chain network. Hackers infiltrate a system through an outside partner or provider with access to systems and data. It can affect software vendors, manufacturing processes, or a service provider in the supply chain.
  1. Zero-Day Exploits: These attacks target vulnerabilities in software or hardware unknown to those interested in mitigating it (including the vendor of the target software). Zero-day exploit advantages attackers because they exploit recently discovered vulnerabilities, with no known defense in place, before the vendor releases a patch to fix them. These attacks can be extremely dangerous because they can go undetected for long periods, allowing hackers extensive access to data or systems.
