Advanced IP Blocker
Advanced IP Blocker is your all-in-one security solution to safeguard your WordPress website from a wide range of threats. This plugin provides a comprehensive suite of tools to automatically detect and block malicious activity, including brute-force attacks, vulnerability scanning, and spam bots. With its intuitive interface, you can easily manage whitelists, blocklists, and view detailed security logs to understand exactly how your site is being protected. Important Note on PHP Version: To ensure maximum security and access to all features, we strongly recommend using PHP 8.1 or higher. Some advanced features (like the local MaxMind database or full 2FA management via WP-CLI) require PHP 8.1. Key Features: * (NEW) File Integrity Scanner (Beta): Instantly detect unauthorized changes to core WordPress files and your active plugins/themes. A vital tool to detect malware infections or backdoor placements on your server. * (NEW) Admin Access Control: Granular control over which administrators can access the plugin’s configuration dashboard. Restrict plugin management while keeping firewall rules intact for all editors and admins. * (NEW) Hardening & Core Protection: Powerful tools to disable WordPress application passwords, turn off the dangerous built-in file editor, block PHP execution in the uploads folder, and hide the WordPress version from attackers. * (NEW) Intelligent Zero-Day WAF Sync: Automatically download and apply critical WAF signatures from the AIB Central Server every day. Stay protected against zero-day vulnerabilities (like wp2shell) without needing to update the plugin manually! The rules run completely independent of your custom WAF configuration. * (NEW) Block Ghost IPs: Automatically block IPs without ASN and Reverse DNS to stop anonymous traffic (Warning: Could cause false positives if rDNS is misconfigured by ISPs). * (NEW) Captcha Integrations (Turnstile & hCaptcha): Seamlessly integrate modern verification challenges like Cloudflare Turnstile and hCaptcha, with granular control per module and a smart fallback to our invisible JS Challenge to prevent accidental lockouts. * (NEW) Rate Limiting Advanced Rules: Create highly specific rate limits for different endpoints. For example, set a strict limit with a Turnstile challenge for /login, while keeping a more generous limit with a temporary block for your main API, all without affecting the rest of the site. * (NEW) Distributed Attack Protection (Auto-Panic): Automatically shields your entire site with a global JS challenge during massive traffic spikes, keeping your server online while intelligently bypassing trusted bots and excluded routes. * IP & ASN Diagnostics Tool: A complete Inspector tool integrated directly into the admin bar. Quickly audit any IP or ASN against your Geolocation database, Threat Scoring system, Spamhaus drops, and manual blocking rules in real-time. * Advanced Rules Import/Export: Seamlessly migrate or backup your complex custom security rules across multiple WordPress websites. With full JSON validation, structural deduplication, and “cost-zero” client-side file generation, agency users can clone their perfect firewall setups in seconds. * Granular JS Challenge Modes: You can now choose exactly how the security challenge behaves. Select “Managed” for ultimate security requiring human interaction (a checkbox), or “Automatic” for an invisible, transparent Proof-of-Work execution that stops bots silently. Apply different modes per module! * Country Selector Copy/Paste: Say goodbye to manually selecting 50+ countries. You can now instantly copy and paste a raw list of 2-letter country codes directly into Geoblocking, Geo-Challenge, and Whitelist Login fields. * AIB Cloud Network V3: Upgrade to the next-generation distributed threat intelligence network. The new API V3 provides secure, individual API Keys per site, drastically improving synchronization reliability, threat telemetry, and global network stability. * Whitelist Login Countries: Take absolute control over administrative access. Easily restrict your WordPress login page and XML-RPC to only allow connections from specific, whitelisted countries, instantly blocking unauthorized foreign login attempts. * (IMPROVED) Bulk Import/Export for Blocked IPs & Whitelist: Seamlessly import massive lists of IPs via CSV or manual entry. The system now features a bulletproof “Bulk Import” type, strict duration inheritance, and intelligent conflict resolution. * Internal Security & Forensics: A complete audit suite solely for WordPress. Track every sensitive event (plugin installs, settings changes, user logins) and monitor your critical files for unauthorized modifications with the integrated File Integrity Monitor. * Activity Audit Log: Gain complete visibility into what’s happening on your site. Who deactivated a plugin? Who changed a setting? The Audit Log answers these questions with timestamped, immutable records. * Deep Scan Email Reports: Get a weekly security summary delivered to your inbox, detailing pending updates, vulnerability status, and recent attack trends. * Username Blocking & Rules: Gain granular control over login security. Creating Advanced Rules to block, challenge, or score specific usernames (e.g., “admin”, “test”). * Enhanced Lockdown Notifications: Distributed Lockdowns (404/403) now fully support Email and Push notifications, ensuring you never miss a critical security event. * Improved Logging: New “Endpoint Challenge” event type provides deeper visibility into challenges served during automated lockdowns. * Server IP Reputation Check. Instantly audit your web server’s IP address against major blacklists (Spamhaus, AbuseIPDB) to diagnose SEO and email delivery issues. * **HTTP Security Headers. Easily configure essential security headers like HSTS, X-Frame-Options, and Permissions-Policy to harden your site against clickjacking, sniffing, and other browser-based attacks. Includes a “Report-Only” mode for CSP. * Site Health & Vulnerability Scanner. Audit your WordPress environment instantly. Detects outdated plugins, insecure PHP versions, and checks your installed plugins against a database of 30,000+ known vulnerabilities. * **PERFORMANCE BOOST: High-Speed Community Database. Migrated the “Community Defense Network” blocklist to a dedicated, indexed database table. This allows checking thousands of malicious IPs in microseconds with zero impact on site memory usage. * **Community Defense Network. Join forces with other WordPress admins. The plugin now shares anonymous attack data to build a global, real-time blocklist of verified threats. Protect your site with community-powered intelligence. * **Auto-Cleaning Logic. Smart expiration handling ensures your blocklists stay fresh and performant, automatically removing stale IPs from both the database and external firewalls (Cloudflare/.htaccess). * **Cloud Edge Defense (Cloudflare). Connect your site directly to Cloudflare’s global network. Automatically sync your blocklists to the cloud to stop attackers before they reach your server. Zero server load protection. * **Server-Level Firewall (.htaccess). Extreme performance upgrade. Write blocking rules and file hardening protections directly to your .htaccess file. Blocks threats instantly without loading PHP or WordPress. * **IMPROVED: Smart Bot Verification. Enhanced logic to correctly identify legitimate traffic from iOS devices (iCloud Private Relay) and social media previews, eliminating false positives while keeping impostors out. * **File Hardening. Protect your most sensitive files (wp-config.php, readme.html, .git) at the server level with a single click. * AbuseIPDB Integration. Proactively block attackers before they strike. The plugin can now check visitor IPs against AbuseIPDB’s real-time, crowdsourced database of malicious IPs and block those with a high abuse score on their very first request. * Edge Firewall Mode! Protect any PHP file or standalone application within your WordPress directory (even if it’s not part of WordPress). Ideal for securing custom scripts, legacy applications, or folders like /scan/. (Requires manual configuration). * Advanced Rules Engine! Create powerful, custom security rules with multiple conditions (IP, Country, ASN, URI, User-Agent, Request Method, Referer) and actions (Block, Challenge, or add Threat Score). * Known Bot Verification. A powerful new security layer that uses reverse DNS lookups to verify legitimate crawlers like Googlebot and Bingbot. This completely neutralizes attackers who try to bypass security rules by faking their User-Agent, assigning high threat scores to impostors. * Verify Monitoring Bots (IP List). A brand new feature that downloads and caches official IP lists from popular uptime monitoring services (like UptimeRobot and Pingdom) to ensure they are never incorrectly blocked or challenged. * Onboarding Setup Wizard. A brand new step-by-step wizard that guides new users through the essential security configurations (IP whitelisting, WAF, and bot traps) in under a minute, ensuring a strong security posture from day one. * Major Refactor: Codebase Modernization. The entire plugin architecture has been refactored into a modern, modular structure. Logic for admin pages, AJAX, actions, and settings is now handled by dedicated classes, making the plugin more stable, performant, and easier to maintain and extend in the future. * Advanced IP Spoofing Protection. A zero-trust “Trusted Proxies” system ensures the plugin always identifies the true visitor IP, even behind complex setups like Cloudflare or a custom reverse proxy. It neutralizes attacks that attempt to fake their IP, preventing block evasion and the framing of innocent users. * Geo-Challenge. A smarter way to handle traffic from high-risk countries. Instead of a hard block, it presents a quick, invisible JavaScript challenge that stops bots but is seamless for human visitors. This reduces unwanted traffic without affecting potential legitimate users. * ENHANCEMENT: Full Bulk-Action Support. IP management is now faster than ever. Both the Whitelist and the Blocked IPs list now support full bulk actions, allowing you to select and remove multiple entries at once, or unblock all IPs with a single click. * Endpoint Lockdown Mode: Automatically shields wp-login.php and xmlrpc.php with a JavaScript challenge during sustained distributed attacks, preventing server overload. * Two-Factor Authentication (2FA): Secure user accounts with industry-standard TOTP authentication, backup codes, role enforcement, and a central admin management dashboard. * IP Trust & Threat Scoring System: An intelligent defense that assigns “threat points” to IPs for malicious actions, blocking them only when they reach a configurable score. More accurate and context-aware than simple rules. * Attack Signature Engine: Proactively stops distributed botnet attacks by identifying and blocking the attacker’s “fingerprint” (signature) instead of just individual IPs. * Web Application Firewall (WAF): Block malicious requests (SQLi, XSS, etc.) with a customizable ruleset. * File Integrity Monitor & Quarantine Vault: Automatically scans WordPress core files and the uploads directory for malware, unauthorized modifications, and hidden PHP shells. Safely neutralize threats by moving them to an encrypted Quarantine Vault. * And much more: Rate Limiting, Country & ASN Blocking (with Spamhaus support), ASN Whitelisting, Push Notifications, Google reCAPTCHA, Honeypots, Active User Session Management, and Full WP-CLI Support.

Enables all modules with sensible defaults that won’t interfere with normal site operation. Maximum Security – Strictest settings for high-security sites. Tighter rate limits, stronger CSP rules, mandatory admin notifications. May require fine-tuning for some setups. You can always customize individual settings after applying a preset. Under Attack Mode Is your site under active attack? Activate Under Attack mode with one click and stop malicious traffic instantly: JavaScript challenge – Every visitor must pass an automatic browser verification before accessing your site. Real browsers solve it in seconds, bots get blocked completely Aggressive rate limiting – Requests limited to 30 per minute with 15-minute blocks for offenders HTTP method restriction – Only GET, POST and HEAD allowed; PUT, DELETE, PATCH, OPTIONS and TRACE are blocked Empty user agent blocking – Requests without a user agent header are rejected Full XML-RPC lockdown during the attack REST API restriction – Only authenticated users can access the REST API Auto-deactivation – Mode turns off after 4 hours so you never forget it’s on Email notifications when the mode activates and deactivates HMAC-signed cookies – Verified visitors get a signed cookie so they only see the challenge once Under Attack mode works independently from your preset configuration. Your regular settings are preserved and restored when the mode deactivates. Two-Factor Authentication (2FA) Add a second verification step to your WordPress login: Authenticator app (TOTP) – Google Authenticator, Authy, Microsoft Authenticator or any TOTP-compatible app Email codes – One-time 6-digit verification codes sent via email QR code setup directly in user profiles 10 backup codes for emergency access if you lose your device Configurable grace period for users to set up their authenticator app Trusted devices – optionally let users skip 2FA on recognized devices for 30 days Role-based enforcement – require 2FA for administrators, editors or any role Exclude specific users from 2FA requirements Admin tool to reset TOTP for users who lost their authenticator Configurable code expiry, attempt limits and email sender name User notification emails when 2FA is enabled or the method changes Firewall Protection Block malicious requests before they reach WordPress: SQL injection blocking XSS (Cross-Site Scripting) attack prevention File inclusion protection (LFI/RFI) Directory traversal blocking Bad query string filtering (catches generic suspicious patterns the specific blockers miss) Bad bot detection and blocking Block requests with empty user agent Rate limiting against DDoS and brute force, with optional progressive lockouts IP whitelist and blacklist management (IPv4 and IPv6, with CIDR ranges and wildcards) User-Agent whitelist and blacklist with partial matching Visitor IP detection control – read the real IP directly from the connection (a spoof-proof default) or from a proxy header when behind Cloudflare, a reverse proxy or a load balancer, with an admin notice if a proxy is detected but not configured HTTP method restriction Server-level file protection via .htaccess: block direct access to wp-config.php, .htaccess, wp-includes/ and sensitive files (.log, .sql, .bak, .ini, debug.log, readme.html, etc.), and optionally wp-cron.php external access Block PHP execution in /uploads (one of the most common post-exploit vectors) Disable directory browsing Login Security Stop unauthorized access attempts: Limit login attempts with configurable thresholds Progressive lockouts – longer blocks for repeat offenders Custom login URL – hide wp-login.php from bots Login URL change notifications to all admin-area users Hide login error messages – don’t reveal valid usernames XML-RPC control: leave it on, block only the pingback methods (recommended, it closes the amplification vector while the mobile app and Jetpack keep working), or disable it completely Application passwords control Email notification when an IP is blocked for exceeding login attempts Admin login notifications via email IP whitelist for trusted locations User Security Comprehensive user account protection: Block insecure usernames (admin, test, root, etc.) on new registrations Warn about existing users with insecure usernames so you can rename or remove them Block author scanning – intercept ?author=N URLs so WordPress doesn’t redirect them to /author/USERNAME/ and leak the login slug Force strong passwords with minimum length Password expiration with configurable intervals Password history – prevent reusing old passwords Force password reset – by specific users, by role, or all users (post-hack recovery) Session limits – control concurrent logins per user Session management – view and revoke active sessions Email verification for new registrations Registration approval workflow – manually approve new users Admin account monitoring – alerts for new admins, email changes, password changes, privilege escalation

fix Server fingerprint hiding – the Server: header is neutralized and X-Powered-By and other fingerprinting headers are stripped from responses File Integrity Monitoring Detect unauthorized changes to your files and compromised plugins: WordPress core verification against official checksums Plugin and theme file monitoring with WordPress.org checksums Critical config files (wp-config.php, .htaccess) monitored against baseline, detecting code injection even in files with no official checksum Closed and removed plugins detection – daily check against the WordPress.org repository, flagging any installed plugin closed for malware, security issues or guideline violations, including both explicit closures and silent “removed” takedowns, with per-slug Ignore for legacy plugins you can’t uninstall yet Line-level diff view of changes, with per-file approval workflow Suspicious code scanning for plugins and themes without checksums Extra file detection in plugins and themes (files not in original distribution) Uploads directory scanning for PHP files, double extensions and .htaccess, with smart classification of dangerous rules vs protective ones Root directory scanning for non-core PHP files (common attack vector) String concatenation obfuscation detection Configurable notification levels and an ignore list to dismiss known files Excluded paths and file extensions

serious event is logged, by minimum severity (a new administrator, a closed plugin or a privilege escalation are all logged as Critical) Threshold alerts when a category spikes – firewall blocks, login failures, user, plugin, file integrity, security, system and content events – over a 30-minute, 1, 6 or 24 hour window, counting only warning and critical events so routine activity never trips them A single anti-repeat cooldown keeps a storm of events down to one notice instead of flooding your inbox Active alerts surface in Settings & Tools, the Dashboard, the Configuration Score and the Security Check “Send test email” button to confirm delivery Security Check On-demand security audit built into the Dashboard. No external services, no accounts, no API keys – everything runs on your server: 40+ checks across 6 categories: SSL/TLS, HTTP Headers, WP Exposure, Access & Auth, Sensitive Files and Internal Checks Single 0-100 score with A-E grade, plus per-category breakdown and explanatory details for every check 15 exclusive internal checks impossible from the outside: PHP end-of-life status, pending updates, inactive plugins, closed or removed plugins, file permissions, default salts detection, wp_ table prefix, admin username, administrators without 2FA enrolled, module status, recent audit errors, last File Integrity scan result and whether audit alerts are configured DNS-only reputation lookup against Spamhaus ZEN, Barracuda BRBL and SpamCop SCBL (informational – listings are flagged but don’t deduct from the score) Two-phase scan: fast local checks appear in under a second, remote checks stream in as they complete Weekly automatic scan with opt-in email alert if the score drops by 10+ points or a new critical check starts failing 30-scan history with sparkline trend and delta chip “Go to setting” fix link on every failing check, jumping straight to the exact Vigilant field that resolves it Smart header diagnostics that report “configured but not being served” when a cache/CDN overrides your headers WordPress Hardening Layered protection at the WordPress level – admin, content, head, feeds and database: Lock down the admin: disable the built-in plugin and theme file editor, block installations and updates from the admin area, and force HTTPS for the admin area. Compatible with any hosting layout, respecting values already in place and never overriding them Disable WordPress’s internal page-view cron when you already have a real server-side cron job configured Dashboard warning when debug mode is left enabled in production, so error output never leaks to visitors Hide your WordPress version everywhere it can leak: from the HTML head, from RSS and Atom feeds, and optionally from every script and style URL on the front-end (stripping only the WordPress version itself, leaving plugin and theme cache busting intact) Automatic daily removal of readme.html, license.txt and licencia.txt from the WordPress root, which otherwise expose your version HTML head cleanup – remove the RSD link, Windows Live Writer manifest, shortlink header and REST API discovery link Database hardening – check for the default wp_ table prefix and one-click rename tool with full backup before the change Comment security – honeypot field against spam bots, force moderation on every new comment, close comments on old posts, disable pingbacks and trackbacks Feed management – completely disable RSS and Atom feeds, or only disable them when the site has no published content REST API Security Control API access to your site: Three access modes: public (default WordPress behavior), authenticated only (closes the API to anonymous visitors), or selective (custom allow/block lists) Block user enumeration via /wp-json/wp/v2/users Protect any list of sensitive endpoints from anonymous access Per-plugin compatibility toggles so authenticated mode doesn’t break the front-end: WooCommerce, Contact Form 7, Gravity Forms, WPForms, Elementor, Jetpack. oEmbed and Site Health endpoints stay accessible by default Security Tools Utilities included: Database Backup – Download a full or partial database backup as ZIP with table selection Database Prefix Change – Change the default wp_ prefix to a random secure prefix Export/Import Settings – Transfer your configuration between sites Manual Backup – Create backups of .htaccess and wp-config.php on demand Reset to Defaults – Start fresh with one click Safe by Design Your existing .htaccess, wp-config.php and robots.txt are automatically backed up before any modifications. Backups are stored in the WordPress database, never as files under the web root, and verified with MD5 checksums.
