About this tool.
KossLabs Anti-Carding & Bot Shield protects online merchants from card testing fraud (carding attacks) by intercepting automated bot submissions before they reach payment gateways such as Stripe, PayPal, Square, or local payment providers.
When carding fraudsters target a WooCommerce store, they automate thousands of micro-authorization attempts using stolen credit card dumps. Even when transactions fail, merchants incur expensive authorization fees ($0.15 – $0.50 per attempt) and risk payment account suspension.
This plugin delivers a 4-layer zero-bloat defense that halts card testing attacks at the gateway threshold without adding custom database tables:
- Layer 1: Invisible Honeypot Trap: Traps naive automated bots that blindly fill all form inputs.
- Layer 2: Cryptographic Timestamp Token: Blocks headless scripts that submit forms faster than humanly possible (< 1.5 seconds) using HMAC-signed tokens.
- Layer 3: Cloudflare Turnstile (Bring Your Own Key – BYOK): Frictionless, privacy-friendly bot challenge. Store owners use their own free Cloudflare credentials—no third-party proxy or developer API quota shared.
- Layer 4: Transient IP Rate Limiter: Enforces strict attempt thresholds per IP (e.g., 3 failed attempts in 10 minutes) stored entirely in RAM (Transients API / Redis / Memcached).
- Dual-Shield Architecture: Full compatibility with Classic Checkout and modern WooCommerce Blocks Store API ( /wp-json/wc/store/v1/checkout ).
