Top 10 Most Common Types of Cyber Attacks

Top 10 Most Common Types of Cyber Attacks has various categories of information security threats, such as network threats, host threats, and application threats, and various attack vectors, such as viruses, worms, botnets, that might affect an organization’s information security.

This section introduces you to the motives, goals, and objectives of information security Cyber Attacks, top information security attack vectors, information security threat categories, and the types of Cyber Attacks on a system Below is a list of information security attack vectors through which an attacker can gain access to a computer or network server to deliver a payload or malicious outcome.

A cyber attack is any sort of offensive action that targets computer information systems, infrastructures, computer networks or personal computer devices, using various methods to steal, alter or destroy data or information systems. These cyber attacks you can learn in CEH v10.

Top 10 Most Common Types of Cyber Attacks

1.Cloud Computing Threats:

Cloud computing provides several benefits, like speed and efficiency via dynamic scaling. However it additionally raises a number of issues regarding security threats, like information breaches, human error, malicious insiders, account hijacking, and DDoS attacks. Clouded computing is an on-demand delivery of IT capabilities in which IT infrastructure and applications are provided to subscribers as a metered service over a network. Clients can store sensitive information on the cloud. Flaw in one Client’s application cloud could potentially allow attackers to access another client’s data.

2.Advanced Persistent Threats (APT):

Advanced Persistent Threat (APT) is an Cyber attacks that focuses on stealing information from the victim machine without its user being aware of it. These attacks are generally targeted at large companies and government networks. APT attacks are slow in nature, so the effect on computer performance and Internet connections is negligible. APTs exploit vulnerabilities in the applications running on a computer, operating system, and embedded systems.

3.Viruses and Worms:

Viruses and worms are the most prevalent networking threats, capable of infecting a network within seconds. A virus is a self-replicating program that produces a copy of itself by attaching to another program, computer boot sector or document. A worm is a malicious program that replicates,Executes and spreads across network connections. A computer worm could be a standalone malware computer program that replicates itself so as to unfold to alternative computers. Often, it uses a computer network to spread itself, looking forward to security failures on the target computer to access it. Viruses make their way into the computer when the attacker shares a malicious file containing it with the victim through the Internet, or through any removable media. Worms enter a network when the victim downloads a malicious file, opens a Spam mail or browses a malicious website.


Ransom ware is a type of a malware, which restricts access to the computer system’s files and folders and demands an online ransom payment to the malware creator(s) in order to remove the restrictions. Ransom ware could be a subset of malware during which the information on a victim’s computer is locked, usually by encoding, and payment is demanded before the ransomed information is decrypted and access is came back to the victim. The motive for ransom ware attacks is almost continually financial, and in contrast to alternative kinds of Cyber Attacks, the victim is sometimes notified that AN exploit has occurred and is given directions for the way to endure the attack It is generally spread via malicious attachments to email messages, infected software applications, infected disks or compromised websites.

5.Mobile Threats:

Attackers are increasingly focusing on mobile devices, due to the increased Adoption of smart phones for business and personal use and their comparatively fewer security controls. Users may download malware applications (APKs) onto their smartphones, which can damage other applications and data and convey sensitive information to attackers. Attackers can remotely access a smartphone’s camera and recording app to view user activities and track voice communications, which can aid them in an attack.Like viruses and spyware that may infect your computer, there are a variety of security threats that may have an effect on mobile devices. We tend to divide these mobile threats into many categories: application-based threats, web-based threats, network-based threats and physical threats.


An attacker can usually target computers not safeguarded with firewalls and/or anti-virus software. A botnet manipulator will get management of a computer in a variety of ways in which, however most often will therefore via viruses or worms. Botnets are important as a result of they need become tools that each hackers and arranged crime use to perform extralegal activities on-line. As an example, hackers use botnets to launch coordinated denial-of-service attacks, while organized crime uses botnets as ways in which to spam, or send a phishing attack that’s then used for determine theft. A botnet is a huge network of compromised systems used by attackers to perform denial-of-service attacks. Bots, in a botnet, perform tasks such as uploading viruses, sending mails with botnets attached to them, stealing data, and so on. Antivirus programs might fail to find—or even scan for—spyware or botnets. Hence, it is essential to deploy programs specifically designed to find and eliminate such threats.

7.Insider Attack:

Insiders that perform attacks have a definite advantage over external attackers because they need approved system access and additionally is also familiar with network architecture and system policies/procedures. Additionally, there is also less security against insider attacks as a result of several organizations specialize in protection from external attacks.An insider attack is an attack by someone from within an organization who has authorized access to its network and is aware of the network architecture.Insider threats to your network usually involve those who work as workers or contractors of your company. They belong in your facilities and that they often have user accounts in your networks. They understand things regarding your organization that outsiders sometimes don’t–the name of your network administrator, that specific applications you use, what variety of network configuration you’ve got, that vendors you’re employed with.


Phishing is a practice of sending an illegitimate email falsely claiming to be from a legitimate site in an attempt to acquire a user’s personal or account information. Attackers perform phishing attacks by distributing malicious links via some communication channel or mails to obtain private information like account numbers,credit card numbers, mobile numbers, etc. from the victim. Attackers design emails to lure victims such a way that they appear to be from some legitimate source or at times they send malicious links that resemble a legitimate website. Phishing could be a methodology of attempting to collect personal data using deceptive e-mails and websites.

9.Web Application Threats:

Web application attacks like SQL injection, cross-site scripting has made web applications a favorable target for the attackers to steal credentials, set up phishing site, or acquire private information. Majority of such attacks are the result of flawed coding and improper sanitation of input and output data from the web application. Malicious users can try to access your internet application while not your consent. Therefore, you must implement the mandatory security features to protect yourself from new internet application threats: Spoofing, data disclosure and information meddling.

10. loT Threats:

The loT devices connected to the Internet have little or no security that makes them vulnerable to various types of attacks. These devices include many software applications that are used to access the device remotely. Due to the hardware constraints such as memory, battery, etc.The internet and unauthorized physical access to your facilities can continually be risks and that they should be monitored and managed. However it’s simple to lose sight of a usually overlooked cyber-attack surface, and that’s the one on the within.
