Quttera ThreatSign – Web Malware Scanner for WordPress for WordPress Plugin Directory

Quttera ThreatSign protects your WordPress website with multi-layered security:

Malware Detection: Powered by Quttera’s AI-driven heuristic engine, the scanner detects malicious PHP, obfuscated JavaScript, hidden iframes, redirects, spam, SEO malware, and credit-card skimmers targeting checkout pages. The plugin performs on-demand scans directly from your WordPress admin and checks your domain against more than 40 global security authorities, including Google, McAfee, Norton, and Yandex. Detection capabilities are continuously enhanced using insights from Quttera’s worldwide threat intelligence network.

Brute Force Protection: Prevents unauthorized login attempts with IP locking, configurable rate limiting, and environment-aware protection policies. Supports both shared hosting (aggressive locking) and dedicated servers (progressive delays). Includes emergency bypass mechanism for critical situations.

Bot Protection: Layered defense against automated attacks using multi-stage risk evaluation, token-bucket rate limiting, and legitimate bot recognition (Googlebot, Bingbot, etc.). Protects REST API, XML-RPC, and WooCommerce endpoints with endpoint-specific risk scoring.

Admin User Monitoring: Real-time detection and alerting for unauthorized admin additions, removals, and role changes with database audit trail and snapshots.

For complete protection—including automated malware removal, scheduled scanning, WAF, and 24/7 monitoring—you can upgrade to a ThreatSign Website Security plan.
