1. Unexpected Decrease in Website Traffic
A sudden decline in your website’s traffic, despite having Google Analytics properly configured, may indicate that your WordPress site has been compromised.
Various factors can contribute to a sudden decrease in traffic.
For example, malware on your site might be redirecting visitors who are not logged in to malicious websites.
Another reason for the traffic drop could be that Google’s safe browsing tool is alerting users about potential issues with your site.
Every day, Google blacklists approximately 10,000 websites for malware and thousands more for phishing attempts. This highlights the importance of website security for all site owners.
You can assess your site’s safety by using Google’s safe browsing tool to review your safety report.
2. Unauthorized Links Added to Your Website
Data injection is a prevalent indicator of a hacked WordPress site. Hackers often establish a backdoor that allows them to alter your WordPress files and database.
Some hacks may insert links to spammy websites, typically found in the footer of your site, but they can appear anywhere. Simply removing these links does not ensure they won’t reappear.
You need to identify and eliminate the backdoor that allowed this data to be injected into your website. Refer to our guide on locating and removing a backdoor in a compromised WordPress site.
3. Your Website’s Homepage Is Altered
This is likely the most apparent sign, as it is immediately noticeable on your website’s homepage.
Most hacking attempts avoid altering your site’s homepage to stay under the radar for as long as possible.
However, some hackers may choose to deface your website to publicly announce the breach. These hackers often replace your homepage with their own message and may even attempt to extort money from site owners.
4. You Cannot Access Your WordPress Admin Panel
If you find yourself unable to log in to your WordPress site, it’s possible that hackers have deleted your admin account.
Without the account, you won’t be able to reset your password through the login page.
There are alternative methods to create an admin account using phpMyAdmin or FTP. However, your site will remain vulnerable until you determine how the hackers gained access.
5. Unrecognized User Accounts in WordPress
If your website allows user registration and you haven’t implemented any spam protection measures, you may find numerous spam user accounts that can be easily removed.
However, if you don’t recall enabling user registration and notice new user accounts appearing in WordPress, it’s likely that your site has been compromised.
Typically, the suspicious account will possess administrator privileges, and in some instances, you may find it impossible to delete from your WordPress admin dashboard.
6. Presence of Unknown Files and Scripts on Your Server
If you’re utilizing a site scanning plugin like Sucuri, it will notify you when it detects any unknown files or scripts on your server.
To locate these files, you should connect to your WordPress site using an FTP client. The /wp-content/ folder is often where malicious files and scripts are found.
These files are usually named to resemble legitimate WordPress files, allowing them to blend in. To identify them, you’ll need to review the file and directory structure. However, simply deleting these files does not ensure they won’t reappear.
7. Your Website Frequently Experiences Slow Loading Times or Unresponsiveness
Every website on the internet is vulnerable to denial of service or DDoS attacks. These attacks utilize numerous compromised computers and servers globally, often employing fake IP addresses.
In some instances, attackers may overwhelm your server with excessive requests, while in others, they may attempt to infiltrate your website.
Such activities can lead to your website becoming slow, unresponsive, or completely unavailable. You can review your server logs to identify IPs making excessive requests and block them, but this may not resolve the issue if there are numerous attackers or if they frequently change their IP addresses.
It’s also possible that your WordPress site is simply experiencing slow performance without being hacked. In that case, you should refer to our guide on enhancing WordPress speed and performance.
8. Unusual Activity in Server Logs
Server logs are text files stored on your web server that document all errors and internet traffic associated with your server.
You can access these logs through the cPanel dashboard of your WordPress hosting account, typically found under Statistics or Metrics.
These server logs can provide valuable insights into what is happening when your WordPress site is under attack.
They also list all the IP addresses that have accessed your website, allowing you to block any suspicious IP addresses.
These errors may not be visible in your WordPress dashboard, yet they could be causing your website to crash or become unresponsive.
9. Issues with Sending or Receiving WordPress Emails
Compromised servers are often used to send spam. Most web hosting providers offer free email accounts, and many WordPress site owners utilize their host’s mail servers for sending emails.
If you cannot send or receive WordPress emails, it may indicate that your mail server has been compromised to distribute spam.
10. Unusual Scheduled Tasks
Web servers allow users to create cron jobs, which are scheduled tasks added to your server. WordPress uses cron for various scheduled activities, such as publishing posts at specific times and clearing out old comments.
Hackers can manipulate cron jobs to execute tasks on your server without your awareness.
To find out more about cron jobs, check our guide on managing WordPress cron jobs.
11. Altered Search Results
If your website’s search results display incorrect titles or meta descriptions, it indicates that your WordPress site may have been hacked.
When you view your WordPress site, you may still see the correct title and description.
The hacker has exploited a backdoor to inject harmful code that alters your site data, making changes that are only visible to search engines.
12. Unwanted Popups or Pop-Under Ads on Your Website
These types of hacks aim to generate revenue by redirecting your website’s traffic to display their own spam advertisements.
These popups are not visible to logged-in users or those who access the website directly.
They only show up for users arriving from search engines. Pop-under ads open in a new window and often go unnoticed by users.
13. Alterations to Core WordPress Files
If your core WordPress files have been altered or modified, it’s a significant indication that your WordPress site has been compromised.
Hackers may modify a core WordPress file to insert their own PHP code or create files with names resembling core WordPress files.
The best way to monitor these files is by using a WordPress security plugin that checks the integrity of your core WordPress files. You can also manually review your WordPress directories for any suspicious files or scripts.
14. Users Are Being Randomly Redirected to Unknown Websites
If your website is redirecting visitors to an unfamiliar site, this is a significant indicator that it may have been compromised.
This type of hack often goes unnoticed because it does not affect logged-in users and may not redirect those who access the site directly by entering the URL in their browser.
These hacks are typically the result of a backdoor or malware that has been installed on your website.
