RX VeX 2.1R

The reasoning core behind every scan.

RX VeX 2.1R is a large, low-latency cyber intelligence model. It fuses a live fetch of the target with a seven-lane audit graph, then writes a /100 report grounded in evidence — not guesses.

2.1R

Current reasoning core — large context, tight decoding, cyber-tuned.

0

Parallel audit lanes scored on every authorized target.

0

Residual risk score — every report is graded /100.

Read-only

Existence and fingerprint only. No exploit payloads. Ever.

How 2.1R thinks

Not a generic chatbot pasted onto headers. A constrained reasoning stack built for authorized website intelligence.

Live-fetch grounding

2.1R never scores a page it did not see. The first pass is a real HTTP fetch — status, headers, body, cookies, redirects — then the model reasons over that packet, not a training memory of the domain.

  • Grounded in the live response
  • Redirect chain preserved
  • No hallucinated headers

Multi-lane evidence fusion

Seven specialist heads run in one pass: security, recon, SEO, performance, privacy, accessibility, technology. Findings are fused into a single residual score so a missing CSP cannot hide behind a perfect title tag.

  • Seven lanes, one /100
  • Critical / medium / low bands
  • Category bars on the report

Constrained decoding

Low-temperature, evidence-first generation. 2.1R is steered to cite what was fetched, rank what to fix, and refuse exploit recipes. Tight sampling keeps reports stable across rescans.

  • T = 0.2 · nucleus 0.95
  • Fix roadmap, not payloads
  • Stable on rescan diffs

Spectral surface memory

The core is fed a Hunt graph, not a homepage. Certificate Transparency names, Wayback CDX history, in-scope crawl, live host probes, and signature fan-out all land in the same context window.

  • 200 in-scope hosts
  • 300 historical URLs
  • httpx-style live probes

Every lane we test

Paste a URL. 2.1R scores each aspect of the target, with evidence you can verify. Examples below are the kind of finding a real scan returns.

Security Lane 01

Headers, TLS, cookies

CSP, HSTS, X-Frame-Options, Referrer-Policy, cookie flags (HttpOnly, Secure, SameSite), certificate and redirect hygiene. Missing controls are treated as ground truth from the live response.

Example
MEDIUM  Missing Content-Security-Policy
target    https://northstar.app
evidence  GET / → 200 · no CSP header
impact    injected scripts run in the victim origin
fix       add_header Content-Security-Policy "default-src 'self'" always;
Recon Lane 02

Attack surface map

Certificate Transparency subdomains, Wayback historical URLs, in-scope crawl, live host probes, JS param harvest, exposed paths, dangling CNAMEs. Fan-out signatures hit more than the URL you typed.

Example
target         northstar.app
Subdomains     14 found
  api.northstar.app
  staging.northstar.app
  cdn.northstar.app
Exposed paths  /.git/HEAD [403]  /admin [302]
Wayback        214 historical URL(s)
Live hosts     9 probed · Fastly
SEO Lane 03

Crawlability & metadata

Title, description, canonical, robots.txt, sitemap.xml, Open Graph. 2.1R flags pages that search engines cannot index — or that leak staging into public metadata.

Example
LOW  robots.txt missing or empty
target    https://northstar.app
evidence  GET /robots.txt → 404
impact    crawlers guess paths; staging may get indexed
fix       publish Disallow rules for /admin /api/internal
Performance Lane 04

Delivery, cache, weight

Compression, caching headers, content-type, page weight signals. Not a lab Lighthouse run — a first-packet read of how the origin actually serves the document.

Example
LOW  HTML served without compression
target    https://northstar.app  ·  1.8 MB document
evidence  Content-Encoding absent on text/html
impact    slower TTFB on mobile / weak links
fix       gzip / brotli on text, json, svg, js
Privacy Lane 05

Trackers & permissions

Third-party scripts, Permissions-Policy, Referrer-Policy, cookie surface. The report covers more than firewalls — what the page phones home to, and what the browser is allowed to do.

Example
MEDIUM  Permissions-Policy missing
target    https://northstar.app
evidence  3 third-party scripts · no Permissions-Policy
impact    camera / mic / geo not explicitly denied
fix       Permissions-Policy: camera=(), microphone=(), geolocation=()
Accessibility Lane 06

A11y basics

Document language, image alts, form labels, heading outline from the fetched HTML. Enough to catch launch-blocking gaps — not a full WCAG audit by a human.

Example
LOW  <html> missing lang
target    https://northstar.app
evidence  root element has no lang · 6 images without alt
impact    screen readers guess the language
fix       <html lang="en">
Technology Lane 07

Stack fingerprint

CDN, WAF, CMS, server tokens, JS libraries. Used to pick the right fix snippets (Nginx vs Cloudflare vs WordPress) and to drive the hunt playbook toward paying checks for that stack.

Example
target  northstar.app
CDN     Fastly
WAF     —
CMS     Ghost
Server  nginx/1.25
playbook  check /ghost/ /rss/ /.well-known/security.txt
Passive-safe ceiling

Smart. Large. Contained.

2.1R is a big model with a small mandate: observe, rank, explain. It will not write exploit PoCs, run authenticated attacks, or scan past program scope.

  • Authorized targets onlyYou paste the URL. Scope tags keep fan-out inside the program.
  • Existence, not exploitationPaths, headers, fingerprints, dangling CNAMEs — never payloads.
  • Operator last mileHackerOne markdown, CWE / CVSS, copy-ready fixes, PDF export.
Weekly drops

Not the final version.

RX VeX ships every week — more surface, more signatures, more watch — until Rx System becomes the main home for bug hunters.

About the engine

What 2.1R is — and what it is not.

RX VeX 2.1R is the current reasoning revision of the RX VeX core — a large cyber language model with constrained decoding and live-fetch grounding. R is the reasoning line.

No. It fetches the URL you authorize, then expands only to in-scope hosts, historical URLs, and signatures. Out-of-scope names are tagged, not attacked.

No. 2.1R maps and ranks. Paste the Hunt graph into Burp or Caido if you need an interactive proof. The report stays existence-and-fingerprint so the product can be hosted.

A /100 score, seven category bars, ranked findings with evidence, a fix roadmap with snippets, HackerOne-ready markdown, PDF export, and rescan diffs.
