7 threat patterns detected

medium

encoded payload

suspicious base64-like blobs detected in page content

critical

brand impersonation

The page hosted on vsb55.com (a 225-day-old unrelated domain) renders a near-perfect replica of Google's CAPTCHA/unusual-traffic interstitial page, including Google branding, Google policy links, and Google support links. The page title is set to 'https://google.com/' and all visible text mimics official Google infrastructure pages to deceive users into believing they are interacting with Google systems. (location: page.html:3, page.html:22-28)

critical

phishing

The site impersonates a Google CAPTCHA verification page on a non-Google domain (vsb55.com). The form posts to 'index' with hidden fields including a 'continue' parameter set to 'https://google.com/', creating a convincing phishing flow that captures CAPTCHA completions and form submissions from users who believe they are on a Google property. (location: page.html:7, page.html:17)

high

malicious redirect

A hidden form field 'continue' is set to 'https://google.com/', which will redirect the user to Google after form submission. This is a classic post-phishing redirect to mask the malicious interception — the user is sent to a legitimate site after credentials or CAPTCHA tokens are harvested, reducing suspicion. (location: page.html:17)

high

credential harvesting

The form contains a hidden input field 'q' with a long opaque base64/encoded token value and a hidden 'continue' field. The form POSTs to 'index' on vsb55.com, meaning any CAPTCHA token, session data, or user interaction data is submitted to the attacker-controlled server before any redirect occurs. This is consistent with harvesting Google reCAPTCHA enterprise tokens or session identifiers. (location: page.html:17)

high

social engineering

The page uses authoritative, fear-inducing language ('Our systems have detected unusual traffic from your computer network') copied verbatim from Google's own error pages. This social engineering technique pressures users into completing the CAPTCHA form on the attacker's domain, lending false legitimacy to the interaction and lowering user suspicion. (location: page.html:24, page-text.txt:21-24)

medium

hidden content

An 'infoDiv' element is present with style 'display:none' and is only revealed on user click. It contains additional Google-impersonating text and links to google.com policy and support pages. This hidden content reinforces the brand impersonation and is not visible on initial page load. (location: page.html:26-28)

FAQ: how to interpret this assessment

Common questions teams ask before deciding whether to use this domain in agent workflows.

Is vsb55.com safe for AI agents to use?

vsb55.com currently scores 24/100 with a suspicious verdict and low confidence. The goal is to protect agents from high-risk context before they act on it. Treat this as a decision signal: higher scores suggest lower observed risk, while lower scores mean you should add review or block this domain.

How should I interpret the score and verdict?

Use the score as a policy threshold: 80–100 is safe, 50–79 is caution, 20–49 is suspicious, and 0–19 is dangerous. Teams often auto-allow safe, require human review for caution/suspicious, and block dangerous.

How does brin compute this domain score?

brin evaluates four dimensions: identity (source trust), behavior (runtime patterns), content (malicious instructions), and graph (relationship risk). Analysis runs in tiers: static signals, deterministic pattern checks, then AI semantic analysis when needed.

What do identity, behavior, content, and graph mean for this domain?

Identity checks source trust, behavior checks unusual runtime patterns, content checks for malicious instructions, and graph checks risky relationships to other entities. Looking at sub-scores helps you understand why an entity passed or failed.

Why does brin scan packages, repos, skills, MCP servers, pages, and commits?

brin performs risk assessments on external context before it reaches an AI agent. It scores that context for threats like prompt injection, hijacking, credential harvesting, and supply chain attacks, so teams can decide whether to block, review, or proceed safely.

Can I rely on a safe verdict as a full security guarantee?

No. A safe verdict means no significant risk signals were detected in this scan. It is not a formal guarantee; assessments are automated and point-in-time, so combine scores with your own controls and periodic re-checks.

When should I re-check before using an entity?

Re-check before high-impact actions such as installs, upgrades, connecting MCP servers, executing remote code, or granting secrets. Use the API in CI or runtime gates so decisions are based on the latest scan.
