Hacked Website - How does it happen?

How serious are the WordPress Malware Attacks?

According to the WordCamp site, there are currently over 75 million sites that use WordPress. While no one actually has the actual number of attacks. The WordFence plugin has been downloaded over 180 million times and protects 4 million WordPress websites.

WordFence reported their customers experience 2800 malicious login attempts per second. WordFence analysis accounts for a very small portion of the WordPress user base.

If malicious attacks rates are consistent. The WordPress platform could easily have 50,000 attacks per-second.

 

The likelihood of the attacks being consistent is slim. Hackers are smart people. They know that attacking a WordPress site without Security is easier to access than one with Security. Attacks on systems without security is more prevalent.

Your Friend Got Your Site Hacked

2021 WordPress Hacks

Shared Hosting Vulnerability 

FINALLY – Sucuri has reported (what I have been telling my clients for years). Shared Hosting requires that all sites are up-to-date. Hackers are able to access a website via the cPanel by first accessing a known vulnerable site on the cPanel hosting. 

For more information on Share Hosting Infections read – Trojan Spyware and Bec Attacks (if you are not techinal jump to the article conclusion).

2021 WordPress Plugin Attacks

Frontend File Manage plugin

WordPress File Management – Riddled with Critical Bugs

Adding a File Management app to your website is not recommended. Leaving it active on your WordPress site can lead to some serious issues, such as deleting all the files and causing trouble with hosting. It just means you’re exposing core installation information and giving everyone who knows how free rein of everything stored on your server. 

Adding a file management plugin has no benefits for websites. Use FTP / SFTP access to manage your server files. 

SEOPress WordPress plugin

Any User can take over Post Titles

Attacker can take the full-use of the site over. With malicious web scripts. 

All users should update the SEOPress WordPress plugin. 

WP User Avatars plugin

Uploading a Backdoor to your website

Yes, this malware attack begins by adding backdoor access to your website. The hacker then installs bogus font plugins to your site that result in redirecting your site visitors to a spam site. 

In the background, the hacker creates a connction with your database and gains access to your administrator users information. And then the clever part of this take over is that the Admin user is exempt from the redirect – keeping the take over hidden from the administeator. 

Fancy Product Designer plugin

Zero-day vulnerability

Yes a harker can take over your site if you are using Fancy Product Designer plugin. WordFence were the first to report that hackes could take over a site using Frany Product Designer plugin.

As a developer and designer – I don’t know why anyone would use the Fancy Product Designer plugin. WooCommence is a top heavy resource sucker – no matter you cache it. WooCommence does require an arsenal of companion plugins (shipping rates, shipping labels, custom orders, coupons, colors, abandoned cart – seriously the list goes on).

Why you would want to add another one-function plugin to a WooCommence enviroment really puts the developer at question (quailty is a choice – you may wanna fire that developer).

Facebook for WordPress Plugin

Two critical severity flaws in Facebook for WordPress (formerly Facebook Pixel). The first flaw allowed hackers to achieve remote code execution.

The second flaw simply had to trick the admin user to click a link and the hackers could inject malicious code into the site.

jQuery Migrate Plugin

The full scale of attack remains undetermined. By injecting Scripts hackers can skim credit card info. And, redirect users to fake sites.

Users were redirected to fake sites. And, prompted to confirm they were not a robot. As of March 2021, the malicious file is undetected by 90% of antivirus engines.

Elementor  Plugin

Compromise the admin accounts. Then using the site to install malicious plugin wpstaff.

4/17/21 – 15 Elementer plugins with over 100 vulnerable endpoints. Allows for “cross-site scripting or malicious JavaScript“. 

Orbit Fox Plugin

Inject malicious code into vulnerable website. And take over the website. 

Popup Builder Plugin

Attackers send out newsletter with their own custom content. Followed by deleting your entire contact list. Let Mailchimp handle your newsletter services. 

123ContactForms Plugin

Sucuri reported the 123ContactForms hack. Attackers are able to use software flaws to create their own posts. And, easily add malicious files to the website.

Contact Form 7 Plugin

Stored cross-site scripting (xss) security bug. 

Ninja Forms Plugin

Critical security Flaws January 2021 & June 2020. 

BUG 1: Authenticated Email Hijacking Account Takeover.

Attacker with subscriber-level access (the lowest access available to WordPress users). 

Bug 2: Authenticated OAuth Connection Key Disclosure.

Low-level users able to trigger and retrieve client_id for established OAuth connections.

Bug 3: Cross-Site Request Forgery to OAuth Service Disconnection.

Attackers could disconnect OAuth connections. Establish a connection with the Ninja Form dashboard – and read mail.

Bug 4: Administrator Open Redirect.

Attacker redirects the admin user to malicious site. And, infecting the admin’s computer with malware.

2020 WordPress Plugin Attacks

Easy WP SMTP Plugin

Hackers were able to identify admin users. Followed by a password reset. Locking the admin user out. And, giving the hacker full control to all site functions and user accounts.

Loginizer Plugin

WordPress developers categorized the security issues affecting the plugin and one-of-the-worst.

WordPress developers pushed an automatic update to all users (even those that had the plugin disabled).

The forced update was the first indicator that WordPress has the ability to automatically update everyone’s plugins – even when they are not active.

NextGEN Gallery Plugin

Here are articles to learn more about the NextGen Plugin hack.

 

Over 530,000 sites are still exposed to attackers. Yes, NextGen Gallery got hit by another hacker. This time, using Remote Code Execution to effectively take over the WordPress site.

NextGEN Gallery acted quickly to provide a patch for the hack. A few days after the release only a small portion of the GalleryGen Gallery plugin had updated to the safe version of the plugin. Leaving more than 530,000 potentially exposed to takeover attacks.

In 2017, NextGen Gallery was attacked with a SQL injection.  Allowing hackers access to the website database. Including sensitive user information.

Ninja Forms Plugin

Threat Intelligence team reported a XSS flaw in Ninja Forms. The plugin flaw let attackers replace contact forms with a malicious form.
