The Story: The Forging of the Ultimate Defense
This project began with a simple goal: to create a lightweight honeypot trap to catch basic bots. But during development, we faced a harsh reality: Simple traps are obsolete. Modern AI bots and headless browsers can easily step over traditional defenses. A basic trap was no longer enough; we needed a fortress.
So, we forged a completely new architecture. We added Proof of Work, Behavioral Analysis, and Rate Limiting. What started as a simple honeypot evolved into a 15-layer invisible firewall. Like a samurai’s blade, it operates with absolute precision—completely invisible to your real customers, yet ruthlessly executing a “Silent Kill” on spam bots before they ever reach your inbox or database.
Samurai Honeypot protects every Contact Form 7 and WPForms form with fifteen independent defense layers. 
Each layer contributes a score, and blocked submissions are handled by a 3-Tier Triage System:
<h4>3-Tier Triage System</h4>
<ul>
<li>Tier 1 (Pass): Score below the threshold (default 50) — email is sent normally.</li>
<li>Tier 2 (Quarantine): Score between the threshold and 99 — email is silently suppressed (Silent Kill) and the submission is saved to the built-in Quarantine Log for admin review.</li>
<li>Tier 3 (Drop / Instant Kill): Score of 100 or higher — email is silently suppressed and the submission is permanently dropped without logging. This protects your database from bloat during DDoS or mass bot attacks.</li>
</ul>
Warning — False Positives: Depending on your environment, legitimate emails may occasionally be flagged as spam. Enterprise proxies, strict corporate firewalls, outdated browsers, VPNs, and unusual network configurations can trigger detection layers. You MUST check the Quarantine Log periodically to identify and recover any false positives. The plugin cannot distinguish all edge cases automatically.
<h4>Defense Layers</h4>
<ol>
<li>JS Injection Gate — Blocks bots that cannot execute JavaScript. Tokens are fetched via REST API for full page-cache compatibility.</li>
<li>Polymorphic Honeypot — Decoy field name is cryptographically derived per token (not exposed in the API response), hidden from humans via CSS.</li>
<li>Token Signature — HMAC-SHA256 signed stateless token with IP and Form ID binding.</li>
<li>Time Trap — Detects impossibly fast submissions. Browser autofill is automatically exempt.</li>
<li>Proof of Work — SHA-256 computational challenge via Web Crypto API that forces CPU cost on bots.</li>
<li>Behavioral Entropy — Hash-verified human-like event counters: mouse, keyboard, touch, scroll. Uniqueness tracking detects script reuse.</li>
<li>Headless UA Block — Server-side User-Agent check instantly blocks known headless browsers and automated tools (Headless Chrome, Puppeteer, PhantomJS, Selenium, Playwright, Nightmare, Electron). Toggleable in settings for E2E testing compatibility.</li>
<li>Headless Detection — Detects automated browser environments (navigator.webdriver, plugin count, window.chrome, language count).</li>
<li>UA Age Detection — Scores based on Chrome version age. 2+ years: +10, 3+ years: +20, 4+ years: +30. Bots often use hardcoded old User-Agent strings that never update.</li>
<li>Rate Limiting — Per-IP submission rate limiting with IPv6 /64 normalization.</li>
<li>Replay Protection — Atomic token consumption (INSERT IGNORE) + TTL expiry enforcement.</li>
<li>IP Blacklist — Manually configured IP/CIDR blacklist for known bad actors.</li>
<li>Content: URL Limit — Flags messages containing more URLs than the configured threshold.</li>
<li>Content: BBCode — Detects BBCode link syntax (<code>[url=...]</code>) that never appears in legitimate form submissions.</li>
<li>Content: Denylist — Matches against WordPress Disallowed Comment Keys (Settings > Discussion).</li>
</ol>
<h4>Key Features</h4>
<ul>
<li>3-Tier Triage — Pass, Quarantine (with local log), or Drop. No legitimate message is lost without a trace — quarantined submissions are saved for admin review.</li>
<li>Built-in Quarantine Log — Blocked Tier 2 submissions are saved to a local database table (up to 1,000 entries, FIFO). View date, score, trigger reasons, and full form data from the admin panel. No external plugin required.</li>
<li>DDoS-Resilient Tier 3 Drop — Submissions scoring 100+ are immediately dropped from memory without any database write. This prevents database exhaustion during mass bot attacks.</li>
<li>GDPR Compliant — No cookies, no external service calls, no plugin-specific PII stored. IP addresses are one-way hashed with a site-specific salt before any storage — raw IPs never touch the database. No consent banner required.</li>
<li>Stateless Tokens — No database writes for token generation; prevents DoS via DB bloat.</li>
<li>Zero Trust Client — All client-submitted data is verified server-side with HMAC signatures and hash integrity checks.</li>
<li>Zero Configuration — Activate and all Contact Form 7 / WPForms forms are protected automatically.</li>
<li>Cache Compatible — Tokens are fetched via REST API, so page caching works fine.</li>
<li>Multiple Forms — Works correctly with multiple forms on the same page.</li>
<li>IP Whitelist / Blacklist — Whitelist trusted IPs or CIDR ranges to skip all scoring. Blacklist known bad IPs to add +100 score instantly. Optionally whitelist all logged-in WordPress users.</li>
<li>Headless Browser Blocking — Server-side User-Agent check instantly blocks Headless Chrome, Puppeteer, Selenium, and other automated browsers (+100 score). Enabled by default; can be toggled off for E2E testing.</li>
<li>Content Rules — Detect spam patterns in form content: excessive URLs, BBCode link syntax, and WordPress Disallowed Comment Keys matching.</li>
<li>Trusted Proxy Support — Optional mode for Cloudflare and reverse proxy environments with IP range validation.</li>
<li>Lightweight — Three PHP files, no external dependencies, no jQuery.</li>
</ul>

Samurai Honeypot for Forms

Invisible 15-layer anti-spam for Contact Form 7 & WPForms. Score-based 3-Tier Triage silently blocks bots — no CAPTCHA, no user friction.

WEB-SHOP-HOSTING

The plugin adds two new Widgets to the Elementor-PRO Forms builder. 
– Phone Country Code – choosing a telephone prefix depending on the country 
– DropZone – Drag & Drop multiple file upload field 
– Advanced Honeypot – Improved up-to-date spam filtering
<h4>Phone Country Code</h4>
<ul>
<li>Telephone prefix depending on the country.</li>
<li>Provides the ability to select a searchable telephone prefix.</li>
<li>The search works both by prefix number and by country name.</li>
<li>The standard for WP language file is used, then it allows to translate the selector depending on the change of the locale inside WP.</li>
<li>In the display of countries there is a flag image, which makes it easier to find and makes it richer. When displaying an empty value, there is an automatic determination of the current country using geolocation based on IP identification.

</ul>
<h4>DropZone</h4>
<ul>
<li>File will be shown in Elementor -> Submission</li>
<li>File can be send by email

</ul>
<h4>Advanced Honeypot – better reCaptcha alternative</h4>
We added an advanced honeypot widget to elementor pro forms. 
<iframe loading="lazy" class="youtube-player" width="750" height="422" src="https://www.youtube.com/embed/102sMMmQsPA?version=3&rel=1&showsearch=0&showinfo=1&iv_load_policy=1&fs=1&hl=en-US&autohide=2&wmode=transparent" allowfullscreen="true" style="border:0;" sandbox="allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox"></iframe> 
This widget is very similar to the native elementor widget, except for very important differences. 
Elementor Form fields can be required or optional. 
Spiders that send spam through forms take into account the presence of traps and try to bypass them, for example, 
they check for the presence of required fields in form and fill in only its so as not to fall into honeypot spam filters. 
The honeypot field that the elementor provides can only be optional, because if you make it required, 
normal visitors will not be able to fill it out, since it is not displayed on the front (it is hidden) and the form simply will not submit by the browser, since the required fields are checked by the browser (even invisible). 
At the same time, it turns out that the optional fields are not filled with spiders just to bypass the honeypot. 
Our honeypot implementation is different in that the honeypot field is always shown as required for spiders, but then this attribute is removed using JavaScript. 
The spider reads only the html and sees that the field is required and fills it in, this causes the spam filter to work. For real visitors, 
this field is invisible and JavaScript removes the mandatory attribute for this field, i.e. spam filter is not activated. 
In addition, the native honeypot field has a “display: none;” style written directly into the input tag that clearly tells the spiders that the field is not visible to users and is a potential trap. 
In our version of the widget, the honeypot field is hidden through styles that are in a common style block that is difficult for spiders to find our traps field.
