Cleaning Up Script Injections That Appear Near the Closing HTML Tag
A recurring malware pattern in older PHP hosting environments was script injection near the closing HTML tag, often from files outside the obvious template layer.
If a site starts outputting random external scripts just before </html>, the first mistake is to inspect only templates and chunks. In many infections the injected code lives elsewhere: compromised core files, writable includes, server-level append handlers, or malicious files dropped outside the expected theme structure.
Where to look first
- recently modified PHP files across the whole project, not only templates
.htaccessfiles and PHP bootstrap files- writable upload folders that now contain executable files
- hosting cron jobs or control-panel injections
- server logs around the time the infection first appeared
Immediate response checklist
- Take the site offline or restrict public access if possible.
- Replace the core and theme files from a clean source.
- Reset FTP, hosting, database, and manager passwords.
- Scan for backdoors, not just visible injected scripts.
- Review file permissions and disable unnecessary write access.
On hacked legacy sites, removing the visible script is never enough. The real job is finding the persistence mechanism that keeps putting it back.
