Injected JavaScript
Trace encoded, remote, conditional, and dynamically created scripts in files and rendered pages.
Fake verification and ClickFix cleanup
Remove fake CAPTCHA malware—and the code that keeps bringing it back.
I clean fake “I’m not a robot,” fake Cloudflare verification, and ClickFix-style malware from WordPress files, database content, injected scripts, plugins, and persistence mechanisms.

Recognize the problem
Common fake CAPTCHA infection symptoms
One symptom does not always confirm a compromise, but several together deserve a careful investigation.
- Visitors see a fake Cloudflare or reCAPTCHA screen
- The page asks users to press Windows+R or paste a command
- Only some visitors, devices, or referrers see the popup
- The browser redirects after clicking “Verify” or “Allow”
- Unknown JavaScript is injected into every page
- The infection disappears temporarily after clearing cache
- Security scanners report social engineering or phishing
- The script returns after a theme or database cleanup
Scope of work
What fake CAPTCHA cleanup investigates
These campaigns commonly use layered injection and conditional display.
Database payloads
Inspect options, widgets, page content, templates, and plugin records that can inject the overlay.
Theme and plugin files
Check modified templates, fake plugins, mu-plugins, loaders, and compromised third-party code.
Persistence mechanisms
Review scheduled tasks, admin users, backdoors, remote includes, and code that restores the injection.
Caching and edge layers
Purge and verify WordPress, server, CDN, and browser caches after the malicious source is removed.
Warning recovery
Confirm visible symptoms are gone before handling Safe Browsing or vendor review steps.
How it works
A clear path from problem to recovery.
- 01
Reproduce the conditional page
Test devices, referrers, logged-out sessions, and rendered source to capture the malicious behavior.
- 02
Trace the injection source
Follow the script back through files, database, plugin hooks, remote loaders, and persistence.
- 03
Remove and harden
Clean the full chain, close the access point where possible, and purge affected caches.
- 04
Retest and review warnings
Verify clean rendering before submitting any external security review.

About MD PabelCommon questions
Before we start.
Is fake CAPTCHA malware dangerous to visitors?+
Yes. Some variants redirect users, request notification permission, steal credentials, or persuade Windows users to run malicious commands through ClickFix-style instructions.
Why can I not see the fake CAPTCHA myself?+
Campaigns often target only logged-out visitors, mobile users, search traffic, certain countries, first visits, or uncached sessions to avoid detection by the site owner.
Can a security plugin remove it completely?+
A plugin may identify a known script, but the injection can also live in database content, custom code, fake plugins, scheduled tasks, remote loaders, or another compromised site in the account.
