Sometimes, cybercriminals may conduct the attack for political or ideological purposes. No matter the intent, a cyber-attack seriously threatens any organization or individual. Everyone must know the most common forms of cyber-attacks and understand how to protect themselves against them.
Examples of cyber-attacks
Below are some examples of common cyber-attacks.
-
SQL injection
SQL injection is a type of cyber-attack that takes advantage of vulnerabilities in web application code to inject malicious SQL statements into the backend database. Attackers exploit these vulnerabilities to access confidential information, modify existing data, or delete data altogether.
It is one of the most common and severe types of cyber-attacks and can have far-reaching consequences. In an SQL injection attack, an attacker attempts to gain unauthorized access to a database by entering malicious commands into web forms or online text boxes.
These commands give an attacker access to the backend database, which allows him or her to extract confidential information or modify the existing data. Attackers frequently exploit SQL injection in applications with poor security measures.
SQL injection is quite serious and has posed a huge threat to many organizations. Every organization should, therefore, be concerned about web application security that does not let any vulnerability pass. This means proper security in regard to databases and the development of web applications by properly coding and testing.
-
Distributed denial-of-service (DDoS)
A distributed denial-of-service (DDoS) attack is one of the most commonly seen cyber-attacks today. It is an attack designed to overwhelm a targeted server or network by flooding it with malicious traffic from multiple sources.
In essence, it is an attack that attempts to take down a website or other online service by flooding it with too much traffic. Hackers can use DDoS attacks for various purposes, such as political activism, sabotage and extortion.
Attackers can also use them to disrupt business operations by temporarily taking down critical systems or causing significant outages. The most common form of DDoS attack utilizes botnets, which are networks of computers that have been infected with malicious software and are controlled remotely.
These botnets can send large amounts of data to the target system to overwhelm it. DDoS attacks may also use specific techniques, such as reflection and amplification, to increase the traffic sent.
-
Cross-site scripting (XSS)
Cross-site scripting (XSS) is an attack that exploits an application’s vulnerability to execute malicious scripts within the user’s browser. This attack targets users by injecting malicious code into websites, web applications or webpages that the user visits.
When a user visits a compromised website or webpage, hackers can use malicious code to access confidential information such as login credentials, cookies and other personal information. XSS attacks are among the most common cyber-attacks, often resulting in data breaches.

These attacks work by exploiting vulnerabilities in web applications. Once the malicious code is injected, it can steal user credentials, redirect users to malicious websites, or inject malicious code into the vulnerable website.
The attacker then can access confidential information and use it for malicious purposes. To protect against XSS attacks, web developers should keep updated on security patches and use encryption when handling user information.
-
Password sniffing attacks
Password sniffing is a cyber-attack in which a malicious actor attempts to capture network traffic to steal sensitive data, including usernames and passwords. These attacks involve packet sniffers or software that can detect, intercept and interpret data as it is transmitted across networks.
This attack aims to obtain user credentials that hackers can use to access the target system. To do this, attackers look for passwords in transit, usually plaintext.
Many of these passwords are transmitted across the connection in plain text and can be sniffed readily by a packet sniffer.
When obtained, the attackers may use the stolen credentials to access other parts of the target system or to launch additional attacks against it.
How to Protect Yourself and Your Business from Cybersecurity Attacks
We are living in a digital world, and the number of cyberattacks is growing day by day. From data breaches to phishing scams, hackers find ways to get their hands on our information.
The following are 10 efficient methods that you can use to protect yourself and your business from cybersecurity attacks.
Use strong passwords
The use of strong passwords in relation to cybersecurity remains one of the best ways of protecting either yourself or your business from cyberattacks. Strong passwords should contain at least eight characters that must combine both uppercase and lowercase letters, numbers, and symbols.
It’s best to avoid using the same password for multiple accounts and not to share your passwords with anyone else. Consider using a password manager to help create and store secure passwords.
Consider enabling two-factor authentication (2FA) as an added security layer. This requires users to provide two forms of identification when signing into their accounts, such as a password and a code sent via text or email.
-
Avoid phishing emails
Phishing is a cyber-attack in which malicious actors attempt to acquire personal information, such as passwords and credit card details, by pretending to be a legitimate source.
Phishers use emails that look like they’re from legitimate sources to trick the recipient into revealing sensitive information or clicking on links that lead to malicious websites. It is important to remember that legitimate companies will never ask for sensitive information via email.
An email that looks suspicious should not be opened or responded to. When it comes to your staff, it is vital to ensure that they are aware of the dangers of phishing emails and that they know how to spot them.
Educate them on the signs of a phishing email, such as spelling mistakes, requests for personal information, or links to unfamiliar websites.
-
Keep your software up to date
With the advancement of technology, the threats of cybersecurity are also growing. Hence, keeping your software updated will help you protect yourself and your business from malicious attacks.
Regular updating of software keeps the bugs and vulnerabilities patched, which helps in the efficient running of the system. You can keep your software up to date by a few methods.

Encrypt important information
Encryption means encoding data so that a user cannot read it without a key or password. When encrypted, data is converted into a form that can only be read by those with the correct key or password.
Encryption is used for both data in transit and data at rest. Data in transit refers to data moving from one location to another, such as an email or file transfer.
On the other hand, data at rest refers to data stored on devices such as computers and phones. When encrypting essential data, you can use several methods depending on your needs.
The most common type of encryption is Advanced Encryption Standard (AES), used for transit data and at rest. You can also use other types of encryption algorithms, such as Twofish and Blowfish, depending on the level of security you need.
Remember that encryption is not foolproof, as someone can still break it if they can access your key or password. This is why it’s important to choose strong passwords and change them frequently and store the key or password in a secure location.
-
Back up your data
Backing up your data is essential for protecting your business from cybersecurity attacks. It’s important to regularly back up sensitive or critical data, such as customer information, financial documents, etc.
