WordPress Malware Recovery and Secure Migration
A compromised WordPress website was fully analyzed, migrated onto a new, trustworthy foundation, and then specifically hardened.
A website that looked normal from the outside
The client contacted us after noticing unusual behavior on their WordPress website. To visitors, the site still appeared to function normally. Behind the scenes, however, there were clear signs of a successful attack.
Outdated plugins
Several extensions hadn't been updated in a long time and presented a possible attack surface.
Obfuscated code in wp-config.php
The central configuration file contained PHP code whose purpose couldn't be explained by normal site operation.
Hidden files inside plugin directories
Additional PHP files had been deliberately placed inside existing plugin folders to avoid immediate detection.
Altered WordPress core files
Files belonging to WordPress core itself had also been manipulated — a sign of an already advanced level of access.
Possible persistent access
Several findings suggested the attacker hadn't just planted malware once, but had established recurring access.
Why we didn't simply clean up the installation
Deleting individual malicious files would have removed the visible symptoms in the short term, without reliably ruling out that an overlooked access point still existed somewhere. So we chose a full, controlled rebuild instead of a repair.
Technical security analysis
The WordPress installation, core files, wp-config.php, plugin directories, uploads, admin accounts, and available server logs were fully reviewed.
Set up a new, clean environment
Instead of copying the compromised installation, a completely new WordPress environment was set up on a separate server.
Migrate only verified content
Only content, media, and data that had been checked and classified as trustworthy were carried over into the new environment.
Reinstall themes and plugins
Every required extension was freshly installed from trustworthy sources in its current version; outdated extensions weren't carried over.
Fully renew all credentials
WordPress security salts, admin passwords, and hosting, FTP/SFTP, and database credentials were all replaced.
Test the site and set up monitoring
Functionality, forms, and key user journeys were checked before backups and ongoing security monitoring were activated.
We review the entire technical environment, not just the visible symptoms.
A resilient security foundation, not a short-term fix
The work wasn't done once the migration succeeded. The new installation received a fully renewed security configuration, so old access credentials couldn't be reused and future anomalies could be caught earlier.
Reduced downtime
The site could go back into operation in a controlled way, without unnecessary delays.
Lower security risk
The rebuild significantly reduced the risk of remaining backdoors or compromised files.
Protected customer data
Renewed access credentials and hardened permissions improved the protection of sensitive information.
Long-term stability
Updated software and a clean system base make reliable ongoing operation easier.
