Is This an UpdraftPlus Vulnerability?-UpdraftPlus WordPress Plugin Security Breach
A common misunderstanding is that the problem was with the UpdraftPlus plugin itself. In fact, the issue was with UpdraftCentral.
TeamUpdraft recommends that all UpdraftPlus users, including those with UpdraftCentral accounts (both paid), update the software. The vendor says the plugin and related files were not damaged in the incident. The only problem was the exposure of user credentials.

The issue was that the UpdraftCentral application treated the provided credentials as valid and allowed access to the user’s account. It seems the UpdraftCentral application is distributed through UpdraftPlus. That means the UpdraftCentral interface might be active on sites where it is not needed.

How Backdoors Work in WordPress-UpdraftPlus WordPress Plugin Security Breach
Most backdoors in WordPress start with some breach, like brute-forcing login pages or using known vulnerabilities. In this case, attackers used the UpdraftCentral connection keys. Since they had permission to send commands, strong passwords could not prevent the breach.

The attackers used the access to install a backdoor in the system. Most of the time, the backdoor stays even after the connection keys are removed. That means disabling UpdraftCentral may not be enough to remove access.

Instructions to Follow in 3 Steps-UpdraftPlus WordPress Plugin Security Breach
If you use UpdraftCentral, know that the connection keys do not identify your site. Still, it’s possible the keys have already been misused. It’s best to follow these steps.
- Update and delete connection keys.
The simplest fix is to update to the latest version. TeamUpdraft says versions 1.26.13 (free) and 2.26.13 (Premium) removed the UpdraftCentral connection strings.

After updating, make sure to delete the keys. Go to Settings – UpdraftPlus Backups – Advanced Tools – UpdraftCentral – Manage existing keys.
- Check the site for signs of an attack.
Attackers often want to keep control of the site. That’s why it’s important to look for keys and check if any plugins appeared without your approval. Watch for activity like new administrator accounts, unauthorized plugins, or unexpected file changes.
Researchers from Patchstack advise checking the UpdraftCentral log. Look for any entries. Pay attention to whether a plugin was uploaded using probing requests. If that happened, your site is likely compromised.

- Make sure you have a safe backup.
Even if your site was attacked, you can try restoring it from a backup… First, check that the backup does not include malicious code. If the backup was made right after the attack, it may contain malware.
If your site is compromised, isolate it, remove the attack vectors, and restore from a backup. Also change all your keys and passwords.
Why This Is Not Just Enough-UpdraftPlus WordPress Plugin Security Breach
Most site owners stop after the step… Remember, the first update, version 1.26.12, had a bug that stopped keys from being deleted. So after updating, attackers could still have access.

Should You Continue Using Remote Administration Tools?
Using remote administration tools is usually fine. These tools are helpful when managing websites… Keep in mind that all traffic goes through one server. If that server is compromised, all connected sites are at risk.
If you use tools, turn on two-factor authentication, allow only necessary servers to connect, and keep software up to date. If you use administration tools, reset all keys and passwords.
Common Errors in the Use of Backup Tools
This incident shows some typical mistakes site owners make. First, relying on one tool makes the site less secure. Pop-up alerts to update software are often ignored. Many WordPress users don’t check the site’s integrity carefully.
Remember, backups are part of the solution. You also need log reviews and monitoring.
