Hidden PHP access
Small loaders, web shells, altered plugin files, or code hidden in uploads can execute commands or restore malware.
Persistent malware cleanup
WordPress keeps getting reinfected?A hidden backdoor may still exist.
Investigation and cleanup for WordPress sites where malicious files, redirects, spam pages, or unknown users return after an earlier malware removal attempt.
What is happening
Backdoors are designed to survive visible cleanup
Attackers may leave several access methods across files, database records, users, scheduled processes, plugins, server configuration, or other sites in the same hosting account.
Rogue users and credentials
Unknown administrators, application passwords, stolen hosting logins, or compromised devices can provide continued access.
Scheduled reinfection
WordPress cron, system cron, must-use plugins, or server tasks can recreate deleted files and database payloads.
Cross-site contamination
Another compromised website under the same hosting account can repeatedly reinfect an otherwise cleaned installation.
The service
Find persistence before declaring the site clean
Backdoor removal requires broader inspection than deleting files reported by a scanner.
01
Establish a clean baseline
Compare WordPress core and known plugin files, review recent modifications, and preserve evidence before cleanup.
02
Inspect persistence points
Review users, application passwords, cron jobs, must-use plugins, uploads, database options, server rules, and sibling sites.
03
Remove malicious access
Delete or repair backdoors, restore legitimate code, remove rogue access, and clean related payloads.
04
Rotate and harden
Change relevant credentials and salts, patch vulnerable software, correct permissions, and verify the website after cleanup.
Important
Cleanup has to address the cause
A malware scanner can miss custom or dormant backdoors
Automated signatures are useful, but a backdoor may be unique, obfuscated, inactive, or hidden inside legitimate-looking code. Investigation should combine integrity checks, access review, logs, file history, and knowledge of how the site is supposed to work.
