How to Clean a Hacked Ghost (Node.js) Blog

Ghost is a modern Node.js publishing platform, so cleaning a compromised Ghost blog differs a little from the PHP world — but the principles are identical. Secure access, remove injected content and files, restore a clean version, and patch the entry point. Here is how to approach it.

Step 1: Secure access

Change your Ghost admin password, your server/hosting credentials, database password, and any API keys or integrations. Take a full backup of the current state first.

Step 2: Look for injected content and files

Compromises in a blog often show as injected scripts in posts or themes, spammy content, or unexpected redirects. Check your theme files, custom code injection settings in Ghost, and the content for unfamiliar scripts. Scan the server — see scanning with Imunify360 — for any uploaded malicious files.

Step 3: Restore clean files

Because Ghost's core is a Node application, the cleanest fix is usually to reinstall Ghost's core fresh (matching your version) and restore your content from a clean backup, rather than trying to disinfect core files individually. Reinstall your theme from a trusted source.

Step 4: Check the database and integrations

Review your content and settings in the database for injected code or unauthorised changes, and revoke any API keys or integrations you do not recognise.

Step 5: Patch and harden

Update Ghost to the latest version, keep Node.js current, secure the admin, and follow the hardening checklist. If your app runs behind a process manager, review it too — see managing a Node.js app.

Frequently asked questions

Where does injected code hide in Ghost?

Often in theme files, in Ghost's code-injection (header/footer) settings, or in post content. Check all three, plus any uploaded files on the server.

Do I reinstall Ghost or clean it?

Reinstalling the core fresh and restoring clean content is usually safer and faster than disinfecting Node core files by hand, since it guarantees the application code is untampered.

How did a Node app get hacked?

Common routes include outdated Ghost or Node versions, vulnerable dependencies, weak admin credentials, or exposed configuration. Update everything and secure access to close these.
