How Do I Know If My Website Has Been Hacked? Key Warning Signs

Realizing that your website has been hacked can be unsettling, but early detection is crucial in minimizing the damage and preventing further compromise. Hackers are often subtle in their methods, and some attacks may go unnoticed for weeks or months. Understanding the key warning signs of a hacked website can help you act quickly to protect your business, data, and customers. In this blog post, we’ll outline the most common indicators that your website may have been compromised.

1. Unexpected Redirects to Unfamiliar Websites

One of the first signs that your website may have been hacked is unexpected redirects. If visitors to your website are being redirected to unfamiliar or malicious websites, it could indicate that the hackers have altered your site’s code.

• What to look for: If your site suddenly redirects users to external pages (often those promoting spam, malware, or adult content), it’s likely that hackers have injected malicious code or altered your site’s configuration.
• How to check: Test your website using different devices and browsers to see if it redirects. You can also use online tools that check for redirect issues.

2. Unusual Changes to Website Content or Files

Hackers often gain access to your website to alter content, insert malicious scripts, or create new user accounts with elevated privileges. If you notice changes to your content that you didn’t make, it’s a sign that someone else has accessed your site.

• What to look for:
  • New or unfamiliar pages or posts
  • Strange or unfamiliar code in your website’s source files
  • Content promoting suspicious products, services, or messages
• How to check: Regularly monitor your website for any unexpected changes. If you’re using a CMS like WordPress, check the file integrity or use a version control system to track changes.

3. Website Performance Slows Down Significantly

If your website suddenly experiences a significant drop in performance, such as slower loading times or frequent downtime, it could be due to a cyberattack. Hackers may install malware on your server, which consumes resources and causes performance issues.

• What to look for:
  • A noticeable increase in loading times
  • The website frequently crashes or times out
  • Error messages like “503 Service Unavailable” or “502 Bad Gateway”
• How to check: Use website performance tools to test the speed of your site, such as Google PageSpeed Insights or GTmetrix. If your site has been compromised, check server logs for any unusual activity.

4. Google or Browser Warnings About Your Website

Search engines and web browsers are becoming increasingly adept at detecting compromised websites. If your website is infected with malware, Google or other browsers may display warnings to visitors, cautioning them that your site may be unsafe.

• What to look for:
  • Warnings from Google search results (e.g., “This site may harm your computer”)
  • Visitors reporting that their browsers flag your website as dangerous or show warning messages
  • Your site being marked as “unsafe” in the Google Search Console
• How to check:
  • Use Google Search Console to see if Google has flagged your site as dangerous.
  • Test your website using tools like Google Safe Browsing or VirusTotal to check for malware.

5. Sudden Drop in Website Traffic

A sharp and unexplained drop in website traffic could signal that your site has been compromised. Hackers may intentionally damage your site’s SEO ranking or block search engines from indexing your content, causing traffic to plummet.

• What to look for:
  • A noticeable drop in organic search traffic
  • Your website being removed from Google search results
  • A significant decrease in conversions or visitors
• How to check: Use Google Analytics or other traffic tracking tools to monitor your site’s traffic. Check your website’s SEO performance in Google Search Console for any sudden changes.

6. Unusual Logins or User Activity

If hackers gain access to your site’s admin panel, they may log in and perform various malicious activities, such as creating fake accounts, altering content, or injecting malware.

• What to look for:
  • Unrecognized user logins or changes in account activity
  • Unusual IP addresses or login locations in the admin panel or user activity logs
  • New admin users or unauthorized changes to existing accounts
• How to check: Regularly review your login and user activity logs. If you notice unfamiliar accounts or activities, it may indicate unauthorized access.

7. New or Unfamiliar Files on Your Server

Hackers often upload malicious files to your website’s server to gain persistent access or spread malware. If you notice new or unfamiliar files in your server directories, it could be a sign of a breach.

• What to look for:
  • New files or scripts in your website’s core directories
  • Files with suspicious names or extensions, such as .php files in a directory where only images should be
  • Files that you don’t remember uploading or installing
• How to check: Use an FTP client or file manager to regularly monitor the files on your server. Compare current files with older backups to identify any changes or additions.

8. Spam and Malware on Your Website

If your website is distributing spam, showing unwanted pop-up ads, or redirecting users to malware sites, it’s a clear indication that your site has been hacked. Malicious code can be injected into your website’s source files or database, leading to this type of activity.

• What to look for:
  • Pop-up ads or unwanted redirects
  • Increased spammy comments or links on your blog or product pages
  • Malware warnings from security software
• How to check: Run malware scanners, such as Sucuri or Wordfence (for WordPress sites), to identify and remove malicious code.

9. Unusual Activity in Your Website’s Database

Hackers may also manipulate your website’s database, stealing data, inserting malicious content, or altering existing records. If your website’s database has been tampered with, it could lead to major issues, including data breaches.

• What to look for:
  • Missing or altered database records
  • Unusual activity such as data being deleted or new records added
  • Unfamiliar IP addresses accessing the database
• How to check: Access your website’s database via phpMyAdmin or a similar database management tool and review recent changes. Look for any suspicious entries or modifications to user records.

10. Emails Sent from Your Domain Without Your Knowledge

Hackers can use your website’s email server to send out spam or phishing emails to your customers or employees. This can lead to damage to your reputation and even legal consequences if your emails are used for malicious purposes.

• What to look for:
  • Complaints from users about receiving spam or phishing emails from your domain
  • Your emails being marked as spam or blocked by email services
  • Unrecognized outgoing emails in your email logs or inbox
• How to check: Review your email server’s logs for any suspicious activity. Make sure your email settings are properly configured to prevent misuse.
