What Are the Common Hack Attacks Made on WordPress Sites?



Popular Hack Attacks: You have just launched a WordPress platform of your own, and things are going well. It’s an easy website, and right now, the bulk of the readers are people who you know. Soon, though, you find that things are not quite right. Weird pop-ups that you didn’t put are there. Or your readers complain that they are being diverted from their mobile devices to other pages as they visit your site.

Chances are that it has compromised the website. It doesn’t matter that yours is not an e-commerce website, or that it doesn’t have any data worth hacking. The thing is, attackers most of the time try to access the server on which the website is running. They try to send out spam from a spot that can not be tracked back to them to do so. There are also other reasons why it gets compromised on a WordPress site. Whatever the case, a list of popular methods used to hack a website is open.

Popular WordPress Websites Hack Attacks

These are some of the most common attacks you should be searching for to defend your website from WordPress:

1. Backdoors:


It helps attackers to access websites even after the website is compromised. Backdoors are corrupted files that cause access controls to be bypassed. For reinfecting and maintaining entry, files are used. This is so many websites are hacked long though the attack has been cleaned up.

2. Remote Code Execution:

If an attacker has access to the admin system of the website through malware installed on the website, they will execute codes on the compromised site remotely. The code can be executed to do something about the website, the server on which the website is stored, or the device from which the website is accessed.

3. Remote and Local File Inclusion:

To include files from a remote or local computer, Attacker takes advantage of insecure inclusion mechanisms. By introducing strict input validation controls, this can be stopped.

4. Broken Authentication and Session Management:

Whenever a user logs into a site, a special Session ID (or Session ID, also known as a Session Cookie) is given to him or her, which must be SSL-protected during the session, random, and time-out as soon as the user logs out of the site. Hackers will do this to assume the identity of the user if the site has a poor authentication scheme. There are the following features of a poor authentication system:

  • Weak session IDs: There is a certain length of strong session IDs, and they use a decent selection of random characters. The website opens up a range of Brute-Force attacks by using characters that are easy to infer, or using a short session ID (more on this attack below).
  • Session IDs revealed in the URL: Session IDs must be confidential, only for the server to be authenticated by the user. Anyone may presume the identity of users or even administrators if your website shows the session ID in its URL.
  • Sessions not timing out: Sessions not timing out are an problem , especially as they provide a foothold for attacks by the Brute Force.
  • Fixation attacks manipulate session IDs: Fixation attacks are a form of session hijacking.
  • Accept weak usernames & passwords, recognise the same passwords: often site administrators use usernames such as ‘admin’ and passwords such as ‘password123’ that are simple to recall. It is impossible to recall a good password because the same password is repeatedly used in a lot of ways several times, which is problematic because once a hacker has their paws on the password, many of the accounts will be at risk of breach.
  • Poor handling of usernames and passwords: Unencrypted protection of usernames and passwords avoids unwanted access to the credentials. Systems with 2-factor authentication aid. It provides an external authentication layer which requires two steps to check the identity of the user requesting to log in.

5. Brute-Force Attacks:


By brute force attack, the most common method of getting access to a site is. It requires guessing the proper username and password combinations by repeated attempts. Hackers have a list of usernames and passwords widely used that they use to hack into a WordPress account. It is important to follow the best practises to deter attacks by brute force.

6. Injection Attacks:

Often hackers use an entry area for malicious code input. Injection is where the attacker’s input order is inserted into the input field using special data. This tricks the execution of commands by the website / web programme. By using strict input validation methods, all these attacks can be stopped and these attacks and file inclusions are identical in this way.

  • SQL injection: This is where an attacker inputs the SQL command / query from input data, enables access to the database, modifies the database and executes admin operations.
  • XSS (cross-site scripting): Injection attack type. Via a web application which accepts inputs, the attacker injects malicious scripts into good websites. Usually, mobile applications detach data and executable code before presenting it to a user’s device. In this scenario, though, the input code is indistinguishable (for instance, when the intruder uses input field markup codes). The user’s browser executes code and offers access to cookies, session tokens, or even HTML page content.
  • MIME misunderstanding attacks: Content-type confusion attacks are sometimes named. Using the propensity of web apps to search file extensions. A file with the proper file extension is submitted by Intruder, and simply includes executable code. For XSS, this opens a trap.

7. Clickjacking:

It brings a user to a different action / different page from the intended button on the intended page on which he / she pressed, often called UI redressing. It’s achieved by building transparent / opaque layers on web pages.

8. DDoS Attacks:

It sends a vast volume of traffic from multiple outlets to an online service, thus flooding it and rendering the platform inaccessible. Done via malware installed on the computers of users who visit infected websites. Computers that are corrupted transform into botnets. To create traffic, botnets can be remotely managed and users are usually unaware of the attack before their site goes down. In 2014, Facebook’s Notes section had a flaw that allowed readers, unknowingly, to join in the attack.

9. DNS Cache Poisoning:

It requires redirecting traffic by the implementation of malicious pages to a DNS to a separate domain. To save time for potential regular searches, DNS caches pages for a short period. If the affected DNS passes malicious page information, it gives users bad data, it may return an incorrect IP address (mostly the hacker’s) through contact to / from another server. It’s risky because it extends this way from the user to the server.

10. Drive-By-Downloads from Malware:

The user is fooled into installing an executable script filled with ransomware, which then retrieves data from the user’s device. Around 60% of WP pages have been compromised with malware used to build drive-by-downloads.

11. Phishing:

Typically it is aimed at e-commerce platforms that hold users’ financial records. Attackers use email or other means of contact to get user data or use a portion of the website to instal spyware that executes one of the following (malicious code that monitors user data):

  • Password and password list for financial website accounts.
  • Searches and retrieves the user’s PC for cache and cookie data.
  • When the financial website is opened, pop-ups demanding a username and password.

12. Symlinking:

Symlinking intrusion attacks are conducted by hackers in order to achieve root access to the entire server of the compromised site. They will have an opportunity to hack a vast number of websites if the domain were on a public server. Web site owners don’t have complete access to their FTP on most shared servers. This restricted access enables them to see only their own home directory material. That way, the content of other users is kept safe. Symlinking, however, helps hackers to access other shared hosting sites.

A connexion to a symbol is a shortcut. When a hacker places the symlink in such a manner that the user believes they’re accessing a certain file when they’re actually not, a symlinking attack happens. What they do is provide the hacker with access to a shortcut that will allow them to search the whole archive.

13. Common Plugin-Based Vulnerabilities on WordPress:


Plugin bugs account for 25 percent of all hacks associated with WP. At some level, all WordPress plugins build vulnerabilities. A developer could have written a poor code or in the new version there were unanticipated loopholes. A fix is easily issued in the form of an upgrade when a flaw is detected in a plugin. If the administrators of the site do not upgrade the site’s themes and plugins, they leave themselves vulnerable to hacking attempts. The more common a compromised plugin is, the greater the probability of a hacking attack. We have listed some of the most prevalent plugin-based vulnerabilities on WP below:

TimThumb: The plugin allows visitors to resize and serve cached image versions from remote, predefined places. This accesses the root directory of the WP. In the plugin, the vulnerability was not. On remote locations accessed, hackers would crack the restriction or upload a script to the cache directory, often with a shell script that would mask the script. This will insert code into and run the WP folders and core files once the blog page is injected. This is a kind of assault using Remote Code Execution.

RevSlider: Patched in 2014, through the Revolution Slider plugin (carousel and slider development plugin), it allowed attackers to instal a ‘Filesman’ backdoor. It requires file access and is concealed in the file structure, making it impossible to detect if server logs are not read.

Arbitrary Upload of Files (via Gravity Forms): Also called Upload of Unregulated Files. Attacker bypasses an app’s access control and uploads a file to an app feature that accepts uploads (via the Gravity Forms plugin in the case of WordPress). The whole website, or even computers, will be used to take over. The intruder will delete vital files after access is taken, fill in the app’s storage with files, or store files in an incorrect position. Patched the flaw. This was a kind of assault on Remote File Inclusion and Execution.

Ultimate Thoughts

We will personally take up each of these general attacks in upcoming posts and address them in depth.

We hope that this collection of vulnerabilities has made you realise why it should no longer be an afterthought for website protection.

The effects of a website being hacked are horrible. When a website is hacked, hackers use the website to conduct malicious operations, as we described earlier. Not just that, as Google discovers that your website is compromised, your domain is blacklisted and your site is disabled even by your hosting company.

To better protect your site from hack attempts, it’s wise to have a WordPress protection plugin such as MalCare built on your website. In a regular basis, the plugin can search your website, clean it if your site is compromised, and also assist you to enforce site hardening steps.
