Understanding Cyber Security Attacks

Cyber Security Attacks attempt to gain unauthorized access to computer systems to steal, expose, change, disable, or destroy information. Similarly, cyberattacks also link to cyberwarfare or cyberterrorism, such as hacktivists, coupled with cybercrime.   Subsequently, there are many reasons behind cybercrime such as below:


Attackers with criminal intent aim to profit financially through data theft, money theft, or company interruption.


For this reason, attackers with socio-political motives try to draw attention to their issues. They consequently publicize their attacks, a practice known as hacktivism.


Similarly to this, those who are personally motivated, like unhappy current or former workers, will steal money, data, or even just the chance to interfere with a business’s system. However, they mainly aim to exact revenge.

Other reasons for cyberattacks include intellectual challenge, blackmail, and spying (to obtain an unfair advantage over rivals).

Classification of the types of cyber security attacks

Internet-based cyber security attacks

These are website or web application attacks.

System-based cyber security attacks

These attacks aim to hack a computer or a networking computer.

Various types of Cyber Security Attacks

Cyber security attacks come in a wide variety and are widespread today. Knowing the different forms of cyberattacks makes it simpler for us to guard our systems and networks against them. Here, we’ll take a closer look at the top twelve cyber-attacks, depending on their size, which can either harm an individual or a major corporation.

Despite how terrifying it may sound, many prevalent security risks may be spotted and prevented. In this post, we’ll examine the various types of cyberattacks that people currently face, as well as prevent them.

1. Malware Cyber Security Attack:

  • The most prevalent sort of security problem is malware. It has existed since the internet’s beginnings and is still a concern. 
  • The term “malware” refers to undesirable software or software that infects a target computer and starts acting abnormally. 
  • This includes restricting access, wiping out files, stealing data, and corrupting other systems.

Prevention from a Malware attack

  • It is the best form of protection, thus being vigilant is necessary. 
  • Users and organizations should, at the very least, have the most recent anti-malware software installed, according to common sense. 
  • Furthermore, using them to distribute malware, suspicious files, URLs, or websites should be recognised. 
  • Antivirus software and knowledge can often thwart the majority of malware attacks.

2. Phishing Cyber Security Attack:

  • An older attacking technique that depends on social engineering is phishing attacks. 
  • Typically, a message or email asking for private information like a password is sent to an end user. 
  • The phishing message may occasionally use official-looking media and addresses to appear official. 
  • An individual persuades by this to click links and unintentionally reveal valuable information

Prevention from a Phishing Attack:

  • Generally speaking, the best form of security prevention is common sense. 
  • Spelling and punctuation problems are frequent in phishing communications. 
  • This is a clear indication that there is malicious intent because official emails from businesses never ask for personal information.

3. Password Cyber Security Attack:

  • ‘Hacked ! ” a typical result comes when your password has been changed and your account information has been lost after logging in. 
  • The truth is that your password was either stolen or guessed by an unwelcome outsider.  The outsider then used it to commit fraud. 
  • For an organization, that might lose important data, it’s even worse. In this attack, a hacker uses software and password-cracking tools like Cain, Abel, John the Ripper, Hashcat, etc. to interpret your password. 
  • Password attacks can take many different forms, including dictionary attacks, brute force attacks, and keylogger attacks. 

Prevention from a Password Attack:

  • Forgetting a password can happen for a variety of reasons. Hackers may attempt to figure out the password or apply “brute force” algorithms to make countless attempts. 
  • They might also take it from a dangerous place or use media manipulation to get someone to give it to them. Given that it requires a second device to complete the login, two-factor authentication is a strong security measure. 
  • Make your passwords strong, and alphanumeric with special characters.
  • Avoid using the same password across several accounts or websites.
  • Update your passwords to reduce the risk of a password attack.
  • Keep any password suggestions hidden from the public view.

4. Man-in-the-Middle Cyber Security Attack:

  • When a third party assembles a session between a client and a host, it is known as a “Man in Middle” attack. 
  • The hacker typically hides behind a fake IP address, disconnects the client, and then asks the customer for details. 
  • A MITM attack could, for instance, take control of a user’s bank account information if they attempted to log into a bank session. 
  • In this attack, the attacker hijacks a client and host session by interrupting two-party communication. Hackers can steal and change data in this manner.
  • The client-server communication has been disabled, as seen here, and the communication channel now passes through the hacker.

Prevention from a Man-in-the-Middle Attack :

  • Clearly, pay attention to the website’s security while you use it. Apply encryption on your gadgets.
  • Avoid accessing open WiFi networks.
  • HTML5 use and protection are advised. Surely, pay attention to the website’s security while you use it. Apply encryption on your gadgets.
  • Avoid accessing open WiFi networks.
  • HTML5 use and protection are advised.

5. Injection Cyber Security Attack:

  • A special code segment introduces into a website search field, the information later manipulates to generate the desired result.
  • for instance, SQL injection and log injection. Injections of XML, code, etc.
  • Most injection attacks are of the SQL injection variety.
  • To interpret and obtain the unauthorized output, a customized SQLi string goes to the web application.
  • As a result, the attacker is now able to access, change, and remove databases’ tables. Additionally, this gives attackers access to admin rights.

Prevention from a SQL injection Attack:

Utilize a system that detects intrusions as they identify unwanted network access.

Prevention from an SQLi injection Cyber Security Attack:

Validate the information that the user has provided. By using a validation procedure, it controls user input.

6. Distributed Denial-of-Service Cyber Security Attack(DDOS)

detailed overview of common DDoS attacks
  • A Denial-of-Service Attack presents a serious threat to organisations. Attackers target systems, servers, or networks in this situation and attack them with traffic to reduce their capacity and resources.
  • When this occurs, the servers get overcrowded with delivering incoming requests, which causes the website to either go down or slow down. The valid service requests go neglected as a result.
  • When attackers combine several hacked systems to perform this attack, it is sometimes called a DDoS (Distributed Denial-of-Service) attack.
  • Attackers using this technique target networks and load them with online traffic. Therefore, the website that a server hosts shut down or perform poorly. Hence, it becomes useless when it cannot handle user requests.
  •  Attackers using this technique target networks and load them with online traffic. The website that a server hosts shut down or perform poorly. Hence, it becomes useless when it cannot handle user requests.

Prevention from a  DDoS Attack:

  • Scan the traffic to find malicious traffic.
  • Identify the warning signs, such as network slowness and frequent website interruptions. In such circumstances, the organization needs to act right away.
  • For one thing, make sure your team and data centre are prepared to manage a DDoS attack by creating an emergency response strategy, keeping a checklist, and more.
  • Finding illegal traffic and blocking access is necessary for stopping a DDoS. Depending on how many rogue IPs are used to spread the assault, this could take some time. For maintenance, servers must typically be taken offline.

7. Insider Threat Cyber Security Attack:

insider type of cyber security attack
  • An internal danger, as the name implies, involves an insider rather than a third party. 
  • In this situation, it can be someone who works for the company and is well-versed in its operations. 
  • The potential damage from insider threats is enormous.
  • Small organisations are particularly vulnerable to insider threats because their employees frequently have access to sensitive data. 
  • There are several causes for this kind of attack, including greed, malice, and even negligence. Insider threats are tricky because they are difficult to predict. There are three types of insider threats which include, a Malicious insider, a Careless insider and a mole.

Prevention from the insider threat Attack:

  • A strong security awareness culture should exist within organisations.
  • Depending on their employment functions, companies must restrict staff access to IT resources.
  • Employers must train their staff to recognise insider risks. Employees will be better able to recognise whether a hacker has tampered with or is attempting to misuse the organization’s data as a result.

8. Crypto-jacking Cyber Security Attack:

  • Cybercriminals can steal a user’s computer or other device and use it to mine cryptocurrencies like Bitcoin. This practice is crypto-jacking. 
  • Fewer people know about crypto-jacking than other attack vectors, so discounting it is wrong. When it comes to this kind of assault, organisations don’t have excellent visibility, thus a hacker can be using priceless network resources to mine a cryptocurrency without the organisation being aware of it. 
  • Of course, stealing valuable data is much more hazardous than taking resources from a commercial network.

Prevention from Crypto-jacking Attack:

  • Monitoring the CPU consumption of all network devices, including any cloud-based infrastructure you utilise, is necessary to defend your network from Crypto-jacking. 
  • Additionally, it’s a good idea to teach your staff to be alert for any performance difficulties or suspicious communications. Furthermore, it might be infected with the crypto-jacking virus.

9. Zero-Day Exploit Cyber Security Attack:

  • To start with, a zero-day exploit occurs when cybercriminals identify a vulnerability in popular software programmes and operating systems.
  • It targets the companies that use those programmes, and use the weakness to their advantage before a remedy is made available. 
  • Accordingly, after a network vulnerability is disclosed, a Zero-Day Exploit occurs; in most circumstances, there is no fix for the issue.
  •  As a result, the vendor alerts consumers to the vulnerability; nevertheless, the info also reaches the attackers.
  • in addition to, the vendor or developer may need any amount of time to address the problem, depending on the severity of the vulnerability. 
  • In the meanwhile, the exposed vulnerability is the focus of the attackers. They make sure to take advantage of the vulnerability even before a patch or other fix is put in place.

Prevention from Zero-day exploits Attack:

  • Since zero-day threats are still unknown, traditional antivirus solutions are ineffective against them. 
  • As a result, there is no method to completely shield against such attacks. 
  • Next-Generation Antivirus (NGAV) solutions, on the other hand, can aid in preventing attackers from downloading unknown software and installing it on a victim’s machine. 
  • Naturally, updating all software will aid in removing vulnerabilities, and having a tried-and-true incident response plan in place will aid in speedy recovery in the event of an infection.

10. DNS Tunnelling Cyber Security Attack:

  • Since a sophisticated attack method called DNS tunnelling is made to offer attackers enduring access to a specific target. 
  • Attackers can “tunnel” or introduce malware into DNS queries since many companies do not keep an eye on DNS traffic for harmful behaviour (DNS requests sent from the client to the server). 
  • Nevertheless, most firewalls are unable to identify the persistent communication channel that the malware is utilised to construct.
  • In a case, to prevent a watering hole attack, it is advised to conceal your online activities. For this, use a VPN and also make use of your browser’s private browsing feature. 
  • Likewise, a VPN delivers a secure connection to another network over the Internet. It acts as a shield for your browsing activity. NordVPN is a good example of a VPN.

Prevention from DNS Tunnelling Attack:

  • For that reason, you will probably need to spend money on specialised solutions like TunnelGuard, Zscaler, and DNSFilter because conventional firewalls and antivirus software cannot detect DNS tunnelling. 
  • Equally important, is to make sure the solutions you employ can automatically prevent malware contained in malicious DNS queries from being executed. 
  • Additionally, it should enable real-time analysis of all DNS queries to look for suspicious trends and ban locations that are known to be used for data exfiltration.
types of cyber security attacks

11. Business Email Compromise (BEC) Cyber Security Attack:

  • In a Business Email Compromise attack, the attacker targets specific people, typically an employee with the authority to approve financial transactions. Hence, uses deception to persuade them to transfer funds to an account under the attacker’s control. 
  • For BEC attacks to be successful, planning and study are typically required. For instance, the attacker can persuade the employee to give over the money by providing any information about the target organization’s executives, workers, customers, business partners, or potential business partners. 
  • Therefore, one of the types of cyberattacks that can cause the most financial harm is BEC attacks.

Prevention from Business Email Compromise (BEC) Attack:

  • Attack Due to Business Email Compromise (BEC) Attack Due to Business Email Compromise (BEC) Attack Due to Business Email Compromise (BEC) Security awareness training is the most effective strategy to stop BEC. 
  • Simultaneously, it is with other phishing assaults. 
  • Also, the employees need to be taught to be on the lookout for emails with a phoney domain, emails that pretend to be from a vendor, emails that seem urgent, and anything else that seems fishy. 

12. Cross-site Scripting (XSS) Cyber Security Attack:

  • Cross-site scripting attacks are very related to SQL injection attacks. 
  • However, instead of stealing information from a database, they usually target other users who visit the website and attack them. 
  • Although, the comments area of a website would be a straightforward illustration. An attacker could post a malicious script into the page if the user input isn’t validated before the post is published. When a user accesses this page, the script will run and may infect their computer, steal information, or even retrieve their login information. 
  • Instead, they can just send the consumer to an unauthorised website.

Prevention from Cross-site Scripting (XSS) Attack:

  • A fundamental familiarity with web development principles and tools, such as HTML and JavaScript.
  • Obviously, it is necessary to understand the complex topic of cross-site scripting. 
  • However, in plain English, the methods used to stop XSS attacks are comparable to those that stop SQL injection assaults. 
  • Anyhow, you must make sure that every input is correctly sanitised to prevent attackers from injecting harmful scripts into websites. 
  • Most importantly, you must take care to prevent your website from rendering any special characters that visitors enter.

Ways to Prevent Cyber Security Attacks

Keep Strong passwords to keep protection from cyber security attacks

  • For several accounts, use several user IDs and password combinations.
  • Apart from this, refrain from noting passwords down. Differing from this, increase the complexity of the passwords by combining letters, numbers, and special characters; the total must be at least 10 characters.
  • As was previously stated, update your password frequently 

Protect your PC

  • Firstly, the activation of a firewall is very important
  • The first line of defence in a network is a firewall, which prevents unauthorised access or fraudulent websites as well as a few viruses and hackers.
  • Furthermore, the application of malware or anti-virus software
  • Primarily, install and use antivirus software to protect your computer from attacks.
  • Apart from this, always avoid spyware attempts
  • In sum by setting up and maintaining anti-spyware software, you can stop spyware from corrupting your computer.

Understand social media

  • Keep your social media profile details private on sites like Facebook, Twitter, YouTube, MSN, and others to prevent cyber security attacks.
  • As a final point, be mindful while sharing and posting any information online. Last but not the least, if you store any data online, it is stored permanently!

Update your operating system at regular intervals

  • Specifically, apply the most recent system versions to keep your programmes and operating system (such as Windows, Mac, or Linux) up to date. 
  • To secure outdated software from future dangers, and enable automatic improvements.

Keep your mobile devices secure

  • Incidentally, stay alert that viruses and hackers can attack your smartphone. 
  • On the other hand, always download software from trusted websites. Keep your mobile devices secure.

Data Protection is important

  • In short, make regular backups of all your essential information. 
  • Secure your most sensitive documents, such as tax records and financial information, and store them somewhere else.

Wireless network security

  • Wireless networks at home are incursion if they aren’t properly secured.
  • Always check default settings and make changes. 
  • Avoid doing any financial or business transactions over public WiFi and hotspots because they are both insecure.
  • Last but not the least, always download software from trusted websites. Keep your mobile devices secure.
