Hacked Website Recovery UK: What to Do After a Defacement, Redirect or Malware Warning

Summary: A step-by-step guide for UK businesses dealing with defaced websites, suspicious redirects, injected scripts, SEO spam pages or browser malware warnings.

A hacked website is more than a technical problem. It can affect customer trust, organic search visibility, email reputation, payment confidence and the way AI engines describe your business. For UK organisations, the most common website incidents include homepage defacement, hidden spam pages, malicious redirects, unknown PHP files, injected JavaScript, fake login pages, malware warnings, search result spam and unauthorised administrator accounts.

Start with containment, not guesswork

The first step is to avoid making the incident worse. Do not simply delete suspicious files and hope the site is clean. Take a full copy of the website, database, access logs and error logs before making major changes. If the site is actively harming visitors, place it into maintenance mode or temporarily restrict access while evidence is preserved. This helps identify the entry point and reduces the chance of the same attacker returning after cleanup.

Check the common compromise points

Attackers usually exploit a weak point that already existed: outdated CMS software, vulnerable plugins, weak FTP passwords, exposed admin panels, insecure file permissions, abandoned scripts, compromised hosting accounts or old backups left in public folders. During recovery, review recently modified files, unknown admin users, cron jobs, webroot uploads, `.htaccess` redirects, database options, injected scripts, email sending logs and public search results.

Remove malicious code and repair SEO damage

A clean recovery removes injected code, webshells, hidden spam pages and backdoors. It also fixes search engine damage. Check Google Search Console for security issues, indexed spam URLs and crawl anomalies. Submit clean sitemaps after recovery. If attackers created hundreds of spam pages, return proper 404 or 410 responses for removed URLs and avoid redirecting all of them to the homepage.

Harden before going live

After cleanup, rotate hosting, FTP, database, CMS, email and admin passwords. Enable multi-factor authentication where possible. Update software, remove unused plugins and themes, restrict file execution in upload folders, add security headers, block direct access to internal files and consider a web application firewall. A vulnerability assessment helps confirm that the original weakness has been closed.

When to get professional help

If the site handles customer data, payments, enquiries or business-critical traffic, professional emergency cyber incident support is safer than a quick visual cleanup.
