Cyber attacks

With the evolution of the internet, every data byte transferred across various networks has led to extensive security requirements. Digital security evolution is an essential issue in the current world. Every data produced and transferred can be highly prone to numerous threats. Cyber attacks are very intentional and malicious efforts. They hack the systems of another organization or individual done by an organization or an individual. Their primary motive is financial gain, data theft, or sabotage.

A cyber attack can be of any format like Computer-network attacks, Supply-chain attacks, Social-networking-led attacks, Attacks on radio networks for GPS and wireless networks, and Radio frequencies with sufficiently high power to interrupt all unprotected electronics in a given geographical surrounding. Hence, Cybersecurity plays a vital role in protecting cyber attacks and strengthening data safety.

Let us have a look at some of the most common cyber attacks. This occurs frequently in malware overall, ransomware, and mobile and cloud malware.

The Most Common Cyber Attacks are

  1. Denial-of-service (DoS) and distributed denial-of-service (DDoS) attacks
  2. Man-in-the-middle (MitM) attack
  3. Phishing and spear-phishing attacks
  4. Drive-by attack
  5. Password attack
  6. Eavesdropping attack
  7. Malware attack

Distributed denial-of-service (DDoS) attacks

A DoS attack overwhelms a system’s resources so that it cannot answer service requests. A DDoS attack is additionally an attack on the system’s help, but it’s launched from an excessive number of other host machines that malicious software controlled by the attacker infects.

Unlike many other cyber attacks designed to enable the attacker to realize or increase access, denial-of-service doesn’t directly benefit attackers. For a few of them, it’s enough to possess the satisfaction of service denial.

However, if the attacked Material belongs to a business, then the benefit to the attacker could also be accurate enough. Another purpose of a DoS attack is to require a system offline so that a special quiet attack is often launched.

Man-in-the-middle (MitM) attack

The attack happens when the hacker inserts itself between a client’s communications and a server. Here are some typical sorts of man-in-the-middle attacks:

Session hijacking

An attacker hijacks between the trusted client and the network server. The attacker substitutes their IP address as the trusted client to Server by disconnecting the client and gaining access to the client data.

IP Spoofing

This is a technique used by attackers to convince the system that it is a known or trusted entity; thus, it communicates with the attacker. In this technique, the attacker uses a trusted host IP instead of their IP address such that the network server thinks it is the known client and accepts the request and acts upon it.

To help prevent man-in-the-middle attacks:

  • Enable Encryptions
  • Use Two-factor Authentications
  • Use a VPN to tunnel the network

Phishing attacks

Phishing attacks send an email to the user to access personal information or influence the user to do something. It is a social trick and engineering by analyzing the user behavior and targeting the user to click on it. Phishing can be an email attachment that contains Malware.

Spear-phishing is a sort of targeted attack on the user. The attacker usually takes a lot of time and effort to research the user behavior. Then, they create the message, so it is too personal and hard to detect this type of phishing attack. The easiest way of Spear phishing is through Email.

Numerous corporations have been severely affected by cyberattacks. A cyberattack could start as a simple phishing email that could capture your employee’s Phishing attempts. This can lead to compromised credentials and lead to personal, financial, and health information breaches, which in turn can be sold and used for marketing fraud and identity theft.

To avoid phishing attacks, follow these steps:

  • Check who sent the mail
  • Double-check with the source
  • Check it with your IT team

Drive-by attack

These are the most common cyber attacks wherein the attacker plants a malicious script in the web page code. The script installs the Malware into the user’s computer or redirects them to the hacker’s site. Drive-by attacks can happen when visiting a webpage or viewing an email or a pop-up window that the attacker is scripting. The main reasons for these attacks are that the browser or the system is not updated to the current version; attackers use it as an advantage and exploit the data.

To protect yourself from drive-by attacks.

  • Keep your browser and System Updated.
  • Stick to the sites you usually visit

Password attack

Password is the mechanism to authenticate a user into the system. Unfortunately, it is a common practice for attackers to take this approach to alter or steal data.

  • Brute force password guessing is that the attacker tries various means to get into the user system. They trying passwords related to the person or similar items.
  • The Dictionary method relies on our habit of picking words as our password, the most common of which hackers have collated into “cracking dictionaries.”

To protect yourself from password attacks. 

  • Always use multi-factor authentication. 
  • Using Biometrics devices 

Eavesdrop attack

These types of cyber attacks occur through the interception of network traffic. An attacker can obtain passwords, card numbers, and other tips. These can directly benefit a user from sending over the network by eavesdropping. Eavesdropping is often passive or active:

Passive eavesdropping: A hacker detects the knowledge by taking note of the message transmission within the network.

Active eavesdropping: A hacker actively grabs the knowledge by disguising himself as a friendly unit and sending queries to transmitters. This is often called probing, scanning, or tampering.

Detecting passive eavesdropping attacks is typically more critical than spotting active ones. Since active cyber attacks require the attacker to understand the knowledge of the friendly units by conducting passive eavesdropping.

Data Encryption is the only way to prevent eavesdropping attacks.

Malware attacks

The unwanted software is installed into the user system without their consent. It can lurk into the application or replicate on the internet. Some of the common types of Malware are 

  • The macro virus affects the application like MS excel, office files. When the infected files are opened, the virus executes attacker instructions before transferring control back to the application. Then, the virus hides and attaches to other parts of the computer system and crashes the files.
  • Ransomware — Malware blocks access to the victim’s data and threatens to publish or delete it unless a ransom is paid. 
  • Droppers — This may be a program that won’t install viruses on computers. In many instances, this isn’t infected with malicious code and, therefore, won’t be detected by virus-scanning software. A dropper can be connected to the internet and download updates to virus software on a user system.
  • Trojans — A Trojan or a computer virus may be a program that hides during an anti-virus scan. It doesn’t self-replicate. Additionally, to launch cyber attacks on the user system, a Trojan quickly can establish a back door that attackers can exploit. 

Stealth viruses

This Malware takes over system functions to hide the corrupted files. They are doing this by compromising anti-virus software to report an infected area as being uninfected.

Final words

Companies providing cybersecurity awareness programs have seen a 72% reduction of any cyber attacks or threats. Employees are the primary target is employees of cybercriminals. Being the first-line defense, employees should be aware of safeguarding all the organization’s data and information. Educating them with cybersecurity awareness training is a crucial element of the workplace. Furthermore, cybersecurity is also evolving, and staying updated is the core difference between keeping your organization safe or vulnerable.
