Even after cleaning the visible malware, attackers often leave hidden backdoors to regain access. We find and remove every one.
A backdoor is a hidden entry point that attackers plant after compromising your WordPress site. Even if you later patch the original vulnerability and clean visible malware, the backdoor lets them walk right back in — often within hours.
Backdoors are designed to be invisible. Common forms include disguised PHP files masquerading as core WordPress files (wp-config-sample.php, wp-ajax.php), base64-encoded payloads injected into functions.php, hidden admin accounts with innocent-looking names, and malicious cron schedules that re-install malware automatically.
Finding backdoors requires scanning every file, checking file hashes against clean WordPress originals, and auditing the database for unauthorized users and scheduled tasks. Missing even one means the infection returns.
Backdoors are almost always installed after a successful exploit — typically through an outdated plugin, vulnerable theme, weak admin password, or insecure file upload form. The backdoor is placed to survive future cleanups. That's why removing malware without finding backdoors rarely works long-term.
Security plugins like Wordfence and Sucuri detect common backdoors but miss custom ones. Sophisticated backdoors use filename spoofing, obfuscation, and legitimate-looking code to evade automated scanners. Manual review by a security analyst catches what scanners cannot.
Most sites are fully cleaned within 24 hours. Complex infections with multiple backdoors across a large codebase may take up to 48 hours. We notify you as soon as the cleanup is complete and verified.
The longer malware stays, the harder recovery becomes.
