VulnTitan security toolkit for WordPress sites. Detect and remove malware, vulnerable plugins, risky file changes, and comment or form spam.

== Description ==

VulnTitan is a WordPress security plugin focused on malware scanning and removal, vulnerability detection, file integrity monitoring, firewall protection, and anti-spam controls for comments and supported forms.

Instantly scan your WordPress site for malware infections and known vulnerabilities, review detailed results, and clean or remove malware safely using a guided fix workflow with automatic backups.

VulnTitan focuses on practical protection: vulnerability detection, malware scanning and removal, file integrity monitoring, firewall protection, anti-spam defense for comments and supported forms, hidden custom login access, and a weekly executive security digest every 7 days.

= Malware Scanner =

The WordPress malware scanner inspects your site files for suspicious code patterns and known malicious signatures.

- Detect malware infections in core, plugins, and themes
- Review problematic files with contextual code preview
- Safe-fix workflow with automatic backups
- Clear severity indicators and actionable recommendations

= Vulnerability Scanner =

The vulnerability scanner checks your installed WordPress core, plugins, and themes against a real-time vulnerability database powered by the VulnTitan API.

- Detect vulnerable plugins and themes
- Identify outdated components with known security risks
- Real-time vulnerability intelligence
- Clear risk explanations and remediation guidance

= File Integrity Scanner =

Monitor unauthorized file changes and unexpected modifications.

- Baseline comparison for WordPress files
- Queue-based processing for performance safety
- Visual status legends for fast review
- Actionable next steps for suspicious changes

= Firewall, Login, Comment & Form Protection =

VulnTitan includes firewall, WAF, login protection, and anti-spam controls to block common attack patterns and protect WordPress login, comment, and supported form submission surfaces.

- Early MU-plugin runtime request guards
- SQL injection (SQLi) payload protection
- Command injection detection
- Suspicious path traversal blocking
- Endpoint whitelisting controls
- Login lockout protection against brute-force attacks
- TOTP-based two-factor authentication for selected roles
- Recovery codes and trusted-device support for enrolled accounts
- CAPTCHA protection for login, registration, lost-password, and optional comment forms
- XML-RPC allow, disable, or rate-limit policy controls with IP allowlisting
- Weak-password blocking during profile updates, password resets, and compatible registrations
- Comment Shield with honeypot, signed tokens, submit-time validation, duplicate detection, guest link limits, IP rate limiting, and moderation-aware logging
- Form Shield for Contact Form 7 and Fluent Forms with honeypot, signed submit tokens, link heuristics, repeated-domain detection, and IP rate limiting
- Form spam blocks are logged into the WAF/live feed with provider-aware source labels for easier review
- Suspicious comments can be held for moderation or blocked immediately
- REST comments can enforce signed anti-spam tokens and CAPTCHA when anonymous REST commenting is enabled elsewhere
- Configurable custom login slug so administrators can use a private login URL instead of the default `wp-login.php`
- Default `wp-login.php` and guest `wp-admin` access can be hidden behind a `404` response when custom login is enabled
- Weekly executive security report email with 7-day firewall, login abuse, WAF, form spam, and comment moderation statistics

= Security-First Architecture =

- Secure storage and cleanup of scan queues and logs
- Hardened backup handling outside `ABSPATH` by default
- Hardened malware and integrity scan actions with stricter capability checks and in-root path validation
- Adaptive performance tuning for safe large-site scanning

= WP-CLI Support =

VulnTitan supports WP-CLI commands for malware, integrity, and vulnerability scans so administrators can run checks from the terminal, scripts, or server automation.

- `wp vulntitan scan malware`
- `wp vulntitan scan integrity`
- `wp vulntitan scan vulnerability`
- `wp vulntitan scan all`
- Optional flags: `--scope=plugins`, `--format=json`, `--fail-on-findings`

== External services ==

This plugin connects to an external API at https://vulntitan.com/api/vulnerabilities to fetch up-to-date vulnerability data for WordPress core, plugins, and themes. This data is essential for detecting known vulnerabilities during scan operations.

When a vulnerability scan is performed, the following data is sent to the VulnTitan API:
- The slug and version of each plugin
- The slug and version of each theme
- The WordPress core version

This data is transmitted only during scans initiated by the user or by scheduled scan settings. No personal, user-identifying, or sensitive site data is collected, transmitted, or stored.

The external service is provided and operated by VulnTitan.com.

1. Upload the extracted `vulntitan` folder to the `/wp-content/plugins/` directory
2. Go to your WordPress dashboard
3. Navigate to **Plugins > Installed Plugins**
4. Find **VulnTitan** and click **Activate**

== Frequently Asked Questions ==

= Who owns the VulnTitan API? =

The VulnTitan API is developed, owned, and maintained by the same team behind this plugin. It is not a third-party service. The API is operated solely to provide accurate and real-time vulnerability intelligence for WordPress sites.

= What data does the plugin send to the API? =

The plugin sends only non-personal technical information such as plugin slugs, theme slugs, and WordPress core version numbers. No personal data, login credentials, email addresses, or sensitive information is transmitted or stored.

= Why is the API connection required? =

The API provides up-to-date vulnerability data needed to detect known security issues affecting WordPress core, plugins, and themes. Without this connection, vulnerability detection would not function correctly.

= Does VulnTitan remove malware? =

Yes. When malware is detected, VulnTitan provides a guided safe-fix workflow with backup protection so you can review and safely remove infected files.

= Does VulnTitan support WP-CLI? =

Yes. VulnTitan includes WP-CLI commands for malware, integrity, vulnerability, and combined scans.

Examples:

- `wp vulntitan scan malware`
- `wp vulntitan scan integrity`
- `wp vulntitan scan vulnerability`
- `wp vulntitan scan all`
- `wp vulntitan scan malware --scope=plugins`
- `wp vulntitan scan all --format=json`
- `wp vulntitan scan vulnerability --fail-on-findings`

= My site is behind a proxy or CDN. How do I configure IP detection? =

If you use Cloudflare, enable "Trust Cloudflare" in **VulnTitan > Firewall > Access Shield > Proxy & CDN**. For other reverse proxies or load balancers, add their IP addresses to "Trusted Proxy IPs". If your site is not behind a proxy or CDN, leave these settings disabled to avoid spoofed IP addresses in logs and lockouts.

= Does VulnTitan protect contact forms from spam? =

Yes. VulnTitan currently supports spam protection for Contact Form 7 and Fluent Forms, alongside native WordPress comment anti-spam controls.
