How to Recover From the Recent cPanel Security Incident (CVE-2026-41940) and Restore an Encrypted WHM Server

The recent cPanel / WHM security issue (CVE-2026-41940) created serious problems for many server owners. In several cases, attackers were able to access vulnerable WHM servers, gain high-level privileges, and damage hosted accounts.

Some affected users reported their website files being encrypted or renamed, similar to past ransomware-style attacks.

One common example was:

wp-config.php

changed into:

wp-config.php.sorry

This type of .sorry extension was seen on important files, making websites stop working immediately.

What To Do First If Your Server Is Affected

If your WHM/cPanel server has already been attacked:

1. Take the Server Offline or Restrict Access

Immediately block public access to WHM/cPanel ports and SSH if suspicious activity is ongoing.

2. Do Not Trust the Existing System

If root access was compromised, the safest option is usually:

Reinstall the server OS
Reinstall cPanel / WHM
Apply all security updates
Change all passwords

Best Recovery Method: Restore From External Backup

Many people were able to recover quickly because they had backups stored outside the server.

Examples:

Google Drive (GDrive)
Remote backup server
Object storage
NAS in another location

If you have clean backups in Google Drive, recovery becomes much easier:

Recovery Process

Fresh reinstall the server
Install cPanel / WHM again
Secure the server and patch vulnerabilities
Download backups from GDrive
Restore cPanel accounts / website data
Test websites and email services

Why Local Backups Are Not Enough

If backups are stored on the same compromised server, attackers may encrypt or delete them too.

That is why offsite backups such as Google Drive can save your business.

How to Protect Your Server Now

Update cPanel Immediately

Make sure your cPanel version includes the security fix.

Use Offsite Automated Backups

At least daily backups to:

Google Drive
Remote storage
Another VPS

Restrict WHM Access

Whitelist your IP for:

2087 (WHM)
2083 (cPanel)

Use Strong Passwords + 2FA

Especially for root, reseller, and admin accounts.

Final Advice

If your server was compromised, trying to “clean” it may not be enough. A full reinstallation + restore from clean Google Drive backup is often the safest and fastest route.
