9 threat patterns detected

medium

encoded payload

suspicious base64-like blobs detected in page content

high

cloaking

Page conditionally redirects based on referrer or user-agent

critical

credential harvesting

The initAccount() function reads 'token', 'account', 'password', and 'loginType' from IndexedDB and transmits them via postMessage to a parent window with wildcard origin '*'. This exfiltrates stored credentials to any listening parent frame without origin validation, enabling cross-origin credential theft. (location: page.html:81 — window.parent.postMessage({ type: 'fixToken', accountInfo: res }, '*'))

critical

credential harvesting

The message event listener accepts 'fixToken' messages from any origin (no origin check on event.origin) and writes received token, account, password, and loginType directly into IndexedDB. This allows any malicious parent frame or cross-origin page to inject or overwrite stored credentials. (location: page.html:85-93 — window.addEventListener('message', ...) with no origin validation)

high

brand impersonation

The domain 637yyt60.com presents itself as 'JiLi168' / 'JiLi168.CC' in all meta tags (og:site_name, og:title, twitter:title, description) while operating from an unrelated random-looking domain. This is a classic brand impersonation pattern where a throwaway domain masquerades as an established gambling brand to lure users. (location: page.html:1-13 — meta og:site_name='JiLi168', og:url='637yyt60.com')

high

social engineering

The page advertises a 'free random sign up bonus' withdrawable after one round of betting — a common gambling social engineering lure designed to harvest user registrations and financial credentials under false incentive pretenses. (location: page.html:1 — meta description: 'get a free random sign up bonus and withdraw it after one round of betting')

high

obfuscated code

window.__APP_CONFIG__ contains a 'domainInfo' field set to a very long Base64-like encoded string (prefixed '==AR3UCR3U...'). This obfuscated payload is decoded at runtime and likely contains configuration data including domain routing, redirect targets, or operator keys hidden from static analysis. (location: page.html:18 — window.__APP_CONFIG__ = { domainInfo: '==AR3UCR3U...' })

medium

malicious redirect

The isInIframe() function checks for a 'unTopWindow=true' URL parameter combined with 'domainType != google' to determine iframe context and alter credential-passing behavior. This parameter-driven branching logic is consistent with cloaking: showing normal content to Google crawlers while enabling credential exfiltration flows for real users embedded in iframe delivery chains. (location: page.html:21-24 — isInIframe() checks unTopWindow and domainType query params)

high

phishing

The site is a 115-day-old domain with a randomized name (637yyt60.com) impersonating the JiLi168 gambling brand, soliciting user registration including account credentials. The combination of brand impersonation, bonus lures, and credential storage/transmission infrastructure is consistent with a phishing operation targeting gambling platform users. (location: metadata.json + page.html — domain age 115 days, brand mismatch between 637yyt60.com and JiLi168.CC)

FAQ: how to interpret this assessment

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

Is 637yyt60.com safe for AI agents to use?

637yyt60.com currently scores 31/100 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.
