high

malicious redirect

Third-party bot detection script loaded from cdn.perfdrive.com (ShieldSquare/Radware) with a beacon URL pointing to eupulse.shieldsquare.net. The inline script on line 26-27 contains invalid JavaScript syntax (bare URLs without quotes: `a.src = u;` where u is `https://cdn.perfdrive.com/aperture/aperture.js` and `ssConf("c1", https://eupulse.shieldsquare.net)`) indicating the rendered source may be tampered or malformed, and all user traffic fingerprints are being exfiltrated to an external third-party domain outside impots.gouv.fr. (location: page.html:16-27)

medium

malicious redirect

Internal help link for FranceConnect troubleshooting points to `http://portus.iia.dgfip/portail/contacts` — a plaintext HTTP internal hostname (`portus.iia.dgfip`) that is not a public government domain and would not resolve for external users, potentially redirecting users to an unexpected or internal-only endpoint. A second identical pattern appears in the FranceConnect help accordion at line 898. (location: page.html:867,898)

medium

hidden content

Mobile app banner (`#banniereSmart`) links to `https://play.test.google.com/store/apps/details?id=fr.gouv.finances.smartphone.android` — note the subdomain `play.test.google.com` instead of the legitimate `play.google.com`. The `test` subdomain is anomalous and may redirect to a non-Google controlled resource or a test/staging environment, potentially serving a malicious APK. (location: page.html:97-99)

low

hidden content

Button label in OTP resend section reads 'Renvoyer le code de sécuritéZZZ' — the trailing 'ZZZ' suffix is a debug/test artifact visible in rendered page text, indicating development residue that should not be in production and suggests the page may not be the genuine production version. (location: page.html:643, page-text.txt:458)

low

hidden content

SMS validation modal submit button reads 'Recevoir le lien de renouvellementTEST' — the trailing 'TEST' suffix is another debug artifact in production-rendered content, further suggesting this may be a staging or tampered copy of the page. (location: page.html:1834, page-text.txt:1164)

low

hidden content

Multiple modal dialogs contain placeholder text 'TITRE' as the literal heading content (e.g., checkSMSMod modal h2, confirmationSpi modal, confirmationPassword modal), indicating incomplete template substitution. This is consistent with a cloned or scraped page where dynamic title injection did not execute. (location: page.html:1749,1877,1927)

medium

credential harvesting

The page collects highly sensitive French tax authority credentials including: 13-digit numéro fiscal (tax ID number), password, 7-digit online access number (numéro d'accès en ligne), revenu fiscal de référence (reference taxable income), date of birth, and 6-digit OTP/unlock codes — all in a single authentication flow. While the domain is legitimate (cfspart.impots.gouv.fr, 39-year-old domain, valid OV TLS cert), the presence of test/debug artifacts (ZZZ, TEST, TITRE placeholders) in production raises the possibility this is a cloned credential-harvesting page mimicking the real DGFiP portal. (location: page.html:259-278,583-585)

low

prompt injection

Base64-encoded value in `__uzdbm_2` JavaScript variable decodes to a session/tracking token containing what appears to be a UUID and an IP address (`fc2177570-d42e-53d8-5352-01030b749a1f$34.96.45.112`). While not a direct prompt injection, this obfuscated variable exfiltrates client fingerprinting data to the ShieldSquare CDN, and its presence could be used to track and manipulate AI agent sessions that render or process this page.

FAQ: how to interpret this assessment

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

Is cfspart.impots.gouv.fr safe for AI agents to use?

cfspart.impots.gouv.fr currently scores 38/100 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.
