原文外掛簡介
Checkout Origin Guard protects your WooCommerce store from fake, fraudulent, or automated checkout attempts by identifying and blocking abusive origins before they clutter your order table or your logs.
The plugin runs client-origin heuristics, IP controls, and sequence analysis to detect non-human traffic and suspicious behavior at checkout. It adds Company Shield for business and email sanity checks and an optional AVS “U” signal handler for gateways that report “Address not checked / unavailable”.
All controls live on a single admin screen; you can adjust sensitivity, manage allowlists and blocklists, and review traffic logs in one place.
Three layers of protection
Bot Block (traffic level)
Detects and throttles abusive requests before they become orders:
Analyzes user agents, referrers, and known bot signatures
Watches rapid-fire hits to checkout and wc-ajax endpoints
Supports monitor, soft, and hard blocking modes
Built-in allowlist for search engines, uptime monitors, and core WordPress services
Company Shield (checkout level)
Validates business identity and email quality at checkout:
Flags suspicious or synthetic business names
Detects repeated syllables, odd vowel ratios, and gibberish patterns
Identifies disposable email domains and role-based accounts (admin, info, sales, etc.)
Can run in:
Monitor; log and annotate orders
Soft; create the order and automatically place it on hold or pending
Hard; block checkout with a user-facing error message
Payment AVS signals (post-payment; optional)
For gateways that expose AVS results in order meta, Checkout Origin Guard can treat “AVS: U; unavailable / not checked” as a risk signal:
Does not change how your gateway authorizes or captures payments
Can be configured to:
Ignore the signal
Add an order note only
Add an order note and bump a risk-score meta field
Put the order on hold for manual review
Uses flexible pattern matching; can scan specific gateway meta keys or fall back to scanning all order meta for common “AVS: U” messages such as the PayPal string
Off by default; you opt in and choose the behavior
Key Features
🛡️ Bot Block; Detects and blocks automated bots by analyzing user agents, referrers, and checkout behavior patterns.
⚡ Rapid Sequence Detection; Monitors frequency and timing between checkout attempts to identify scripted attacks and card testing activity.
🧠 Company Shield; Flags suspicious or AI-generated business names, email domains, and mixed-character spam entries at checkout.
🌎 Allowlist Controls; Preserve access for search engines, uptime monitors, and essential WordPress and WooCommerce services.
🔒 Hard / Soft / Monitor Modes; Choose between logging only, soft blocking, or full hard blocking.
🧾 AVS “U” Risk Signals (optional); Treat “Address not checked / unavailable” as a post-payment risk signal; add notes, increase risk score, or hold the order.
🗂️ Log Viewer; See activity including timestamps, IPs, user agents, paths, and detection outcomes.
🧩 One-Page Dashboard; Configure settings, review logs, and manage allow/deny lists from a single screen.
🚫 Manual Block / Unblock; Instantly remove or restore access for specific IPs with one click.
💾 CSV Export; Download checkout-origin activity logs for security review or record keeping.
Why Online Shops Need it
WooCommerce checkouts are frequent targets for:
Card testing and BIN probing
Fake business registrations and spam accounts
Automated scripts hammering your checkout endpoints
Checkout Origin Guard focuses on checkout behavior and identity quality, not just generic firewall rules. It helps you:
Reduce chargeback and fraud risk
Keep your order list clean and reviewable
Shorten the time spent cleaning up junk orders and bogus signups
The plugin works alongside any existing firewall, CDN, or WAF; it does not rely on external APIs or subscriptions. All data stays on your server.
Use Cases
Prevent card testing or order spam
Stop bots using nonsense or AI-generated company names
Detect rapid repeat checkout attempts from the same IP
Block suspicious POST requests that hit checkout endpoints
Add an extra layer of review for orders where the gateway reports “AVS unavailable / not checked”
Maintain cleaner order history and logs for real customers
