Since it's so widespread and widely used, it's also a frequent attack target for hackers. So, website owners could gain from educating themselves about the latest WordPress security issues and then taking precautions to avoid the occurrence of these problems.
It's good to know that there are many ways to safeguard WordPress. In the event that you're confronted with an unsecured website or want ways to preventatively secure your website, an array of tools, services, and options are available to you.
In this article, we’ll discuss the 7 common WordPress security issues and what you can do to protect your website against those attacks.
WordPress Security Vulnerabilities
WordPress is one of the largest and most well-known CMS worldwide, supplying more than 40% of websites. WordPress is an open-source project, and anyone is able to help in its creation.
Most WordPress security attaches can threaten the security of your site as well as the data of your users. When a hacker infiltrates your website, it could cause prolonged downtime as well as the disclosure of personal information. This can not only affect your business and traffic as a whole, but it may result in long-term harm to the image of your company.
Making sure that your website is secured against the WordPress vulnerability list can reduce your chance of becoming the target of a cyberattack when you stay on top of security and conduct security checks to improve the performance of your website and keep your visitors' trust and data. Keep in mind, if you feel unsure about any of the information we’re going to discuss below, make sure you buy secure WordPress hosting.
1. Brute-Force
An attack using brute force is an extremely popular method of cracking that enables bad actors to figure out login details, making use of automatic password generators.
Types of Brute Force Attacks
Basic brute force attacks: Use an organized method of "guess", which doesn't depend on logic from outside.
A hybrid brute force attack: Starts with external logic in order to figure out which variation of the password could be the most successful before proceeding with an easy method of testing various possible variants.
Dictionary attack: Guesses passwords or usernames with the dictionary of string or phrase.
Rainbow Table Attacks: A rainbow table is a computer-generated table that reverses the cryptographic hash function. The table can be utilized to determine a function to a specified length made up of a number of characters.
A reverse attack on brute force: Uses the same password or a combination of passwords with a variety of potential usernames. The attack targets a group of users that the attackers already have access to data.
Credential filling: Uses known password-username pairs previously and tries them on multiple websites. The attack exploits the fact that many users share the same password and username across various systems.
The most basic solution is to buy a WordPress hosting that is secure.
How to Prevent Brute Force Password Hacking
In order to protect your company against hacking using brute force, ensure the use of high-quality passwords. The passwords you choose should:
Don't use information that can be found on the internet (like the names of relatives).
As the many characters, you want as is possible.
Mix letters, numbers, and other symbols.
Make sure that each user has a different account.
Avoid common patterns.
2. Cross-Site Scripting (XSS)
It is a technique for hacking that uses malicious code derived from input from the user, is introduced into web pages, and is viewed by website visitors. XSS attacks are amongst the common WordPress security issues with all the plugins you tend to install. XSS could be able to steal sensitive data, alter web page functionality, and so on. XSS attacks are when attackers use web applications to communicate malicious code, usually through web-based side scripts that are sent to another end user. The flaws that enable these attacks to work are common and can be found anywhere that an application on the web uses input from users within its output without validating or encoding the input.
What are the kinds of XSS attacks?
There are three major varieties of XSS attacks. The three types include:
Reflected XSS: The harmful script originates from the present HTTP request.
Stored XSS: The harmful script is derived from the database of the site's website.
DOM-based: XSS, which means that the vulnerabilities are in client-side software, not server-side.
What can we do to avoid XSS attacks?
Simple Solution: Anytime an online site is receiving user input, it should be as strict as it is feasible based on the anticipated or legitimate input.
It is easy to prevent cross-site scripting in certain circumstances. However, it could be a lot more difficult in other cases, depending on the sophistication of the program as well as the way it processes information that can be controlled by the user.
The most effective way to prevent XSS weaknesses is likely a mix of these measures:
Filter input upon its arrival: At the point at which inputs from users are accepted, apply the filter as strictly as possible based on the input that is expected to be a valid or acceptable input.
Encode output data: At the point that user-controllable information is displayed via HTTP responses, encode the response so that it cannot be taken as active content. Based on the specific context for output, the process may require different combinations that include HTML, URL, JavaScript, and CSS to encode.
Use appropriate response headers: To prevent XSS in HTTP responses that aren't intended to contain any HTML or JavaScript, you can use the Content-Type and X-Content-Type-Options headers to ensure that browsers interpret the responses in the way you intend.
Content Security Policy: As the last security measure, you can utilize Content Security Policy (CSP) to limit the impact of any XSS security vulnerabilities that are still present.
3. SQL Injection
For this kind of attack, malicious SQL statements are introduced by a user who has not been authorized. SQL injection attacks could be employed to alter details, obtain sensitive data, or even steal sensitive information.
SQL injection examples
There are a variety of SQL injection weaknesses, attack techniques, methods, and vulnerabilities that can be found in various scenarios. Some common SQL injection examples include:
Finding hidden information, in which it is possible to modify the SQL query to provide more outcomes.
In this way, you can subvert the logic of an application. You are able to modify an application's logic.
UNION attacks, in which you are able to retrieve information from multiple databases.
In the process of examining the database, you will be able to find information on the structure and version of your database.
Blind SQL injection occurs when the results of queries that you are in control of do not appear within the application's response.
How to Prevent SQL Injection Attacks?
The most basic solution is to scan your website to identify SQL vulnerabilities through web-based tools for scanning websites like Imunify360.
In order to prevent or reduce SQL injection attacks involves making sure that no fields are susceptible to insecure inputs as well as the execution of applications. It is difficult to effectively check each website and application that is on the web, particularly where updates are frequently made, and the user experience is the first priority. But security specialists and experienced developers suggest a few of the following tips to ensure that your database will remain safe inside the security of your server.
4. Backdoor
A backdoor is a malicious program that contains a method to get around the authentication or login procedure of a site. This is the latest WordPress security issue that occurs when you install unknown plugins and themes.
Types of Backdoor Attacks:
There are two kinds of Backdoor attacks. These are given in the following order:
Attack on the Administrative Backdoor: Sometimes, software makers deliberately include a backdoor into the program to ensure that, if it fails or is a mistake, they are able to get access to the main part of the program's code to quickly fix the issue. Administrative Backdoors is the term used to describe these backdoors. They can aid software testers in validating the software's code.
While the Backdoors can only be discovered by hackers, an experienced hacker could exploit them and utilize the backdoors invisibly for his own advantage. This is why Administrative Backdoors can be regarded as an example of a loophole in the program.
Malicious Backdoor Attacks: The term "malicious Backdoor Attack" is when a program enters the system via malicious malware.RAT (Remote Access Trojan) is the name used by cyber-attackers for installing malware-based backdoors.
Prevention of Backdoor Attack:
Essential defense: Make sure your server is protected by firewall and antivirus protection and that it is up to the latest version. Make sure that you ensure that you keep WordPress, as well as any related plugins, up to date with the most recent security updates.
Prevention is more effective than curing. Here are a few ways to stop Backdoor attacks from happening:
Monitor Continuously of Security System: Monitoring the security system's network assists in identifying loopholes that could become entry points to attack backdoors.
Strong firewalls on Computer Networks: A firewall blocks the flow of data within a computer network, and an effective firewall will stop hackers from gaining access to the network.
Protecting networks with strong passwords: A secure password is essential to ensure the security and strength of the system. It is important to never use default passwords and must use passwords that are tough to crack or guess.
Beware of accessing untrusted and unauthorized sites or content on the web: In particular, it is important to be extra cautious when using sites and software that are not free. They are the perfect home for malware and viruses that can do serious damage to your computer.
5. Denial-Of-Service (DoS)
This kind of attack makes websites inaccessible to users; in this case, an attack known as a Distributed Denial-of-Service (DDoS) attack transmits data from a variety of sources to the website and overwhelms its network connections. Most secure WordPress hosting providers implement anti-ddos configurations and many other configurations to fix common WordPress security issues.
Types of DoS Attacks
There are typically two types of DoS attacks to be aware of, both logic-based and volume-based.
Volume-based attacks: This type of DoS is the type that people are familiar with. When a volume-based attack is used, attackers simply attempt to overwhelm a system or connection with enough communication that it becomes inaccessible or even the service ceases to function altogether.
Logic-Based attacks: In a logic-based attack, the attacker seeks to exploit an issue within a system to shut the service offline. As an example, if an attacker discovers a flaw on a server that is not patched and exploits that flaw to slow down the speed of the server, it could be considered a logic-based hack. The attack didn't require a lot of resources; it just required a "logic" vulnerability to slow down services.
How To Prevent Denial-of-Service (DoS) Attacks
Simple Solution: Utilizing an established Content Delivery Network (CDN) like Cloudflare will reduce or prevent these kinds of attacks.
Denial of service attacks could be difficult to protect against. Businesses can implement these steps to ensure denial of service security and prevention
Analyze and monitor network traffic: The network traffic may be controlled by an intrusion detection or firewall system. Administrators are able to establish rules to create alerts when there is unusual activity and identify the source of traffic or remove network traffic that meets some criteria.
Increase their security: This includes fortifying any devices that are connected to the internet to guard against attack, installing and keeping antivirus software up-to-date, setting up firewalls designed to defend against DoS attacks, and adhering to strict security guidelines to track and control unwanted traffic.
Monitor traffic: Businesses can sign up for an online service that monitors or redirects traffic flow patterns that are typically caused by a DoS attack while still allowing normal traffic to flow across the network.
Develop the DoS attack plan for response: The key is to develop and implement the disaster recovery strategy for the DoS attack that includes communication, mitigation, and recovery.
6. Phishing
The phishing method is used by attackers to impersonate legitimate companies, generally via email, to collect details about the person they are targeting. They then use the details to hack into the website or to commit fraud. Phishing is the most common WordPress security vulnerability since it can target people who work for your website.
In the typical phishing scam, fraudsters send out fake emails to a large number of individuals seeking sensitive data (such as bank information) as well as hyperlinks to harmful websites. They may try to trick users into paying money, get your information and then sell it to others, or possess political or ideological motivations to gain access to your company's data. These emails are becoming more difficult to detect, but they are still able to get through to even the most attentive customers. Whatever your business is, however large or tiny it is, you'll be hit with the threat of phishing at some time.
Types of Phishing Attacks
Fraudulent email phishing: Fraudulent messages are sent to users who are not known via email in large quantities.
Spear Phish: Highly targeted type of phishing targeted at particular users.
Whaling Big: Sharks such as CEOs or any other high-level executives are targeted by detailed analysis.
Smishing Fraudulent: SMS alerts are part of this phishing scam.
Vishing Phishing: Is orchestrated through phone calls or any other media that relies on voice.
Pharming The victim: It’s redirected by fake websites by DNS poisoning of caches.
Phishing through social media: Social platforms are being used in this kind of attack.
Methods to Prevent Phishing Attacks:
Simple Solution: Spam filters identify and block the majority of malicious messages from getting into users' mailboxes.
Inform your employees about the dangers and hold workshops using mock scenarios of phishing.
Set up a SPAM filter to detect virus-ridden senders, empty addresses, and so on.
Be sure to keep your system up-to-date using the latest security patches and updates.
Install an antivirus program, set up signature updates on a regular basis, and check the status of the antivirus across all devices.
Make a security strategy that includes, but isn't restricted to, the expiration of passwords and their complexity.
Install a filter on the web to stop malicious websites.
All sensitive information of the company should be encrypted.
Convert HTML emails into text-only emails or deactivate HTML emails.
Employers must be protected by encryption if they telecommute.
There are a variety of steps that companies can take to guard against the WordPress vulnerability list and the threat of phishing. The company must stay up-to-date with the latest phishing tactics and verify its security policy and strategies to eliminate risks in the future as they develop. Equally crucial is to ensure that they are aware of the different types of threats they could encounter, their risks, and the best way to deal with the threats. A well-informed workforce and secure system are crucial to safeguard your business from attacks by phish.
7. Hotlinking
It is a method in which a site links directly to a targeted site's assets, including images or videos, to improve the SEO rank of a website or feature content without utilizing the resources of its server or bandwidth. In the example above, if website B hotlinks to site A's image featured on the page, and the website receives lots of visitors to the webpage with the image, then website A's server resources will be depleted, which could impact the performance of website A.
How to Prevent Hotlinking
The most basic solution is to use the plugin or the Content Delivery Network (CDN), such as Cloudflare, to protect the media documents.
