Do not pay, sign in, or share personal details with this site. Labels: Sensitive Interaction Risk, Governance Risk Assessed 2026-08-20 by automated analysis. Classification confidence 55%. | Field | Value | | --- | --- | | What this site appears to be | A simple 429 Too Many Requests error page indicating the client has exceeded allowed request rate. No interactive elements, forms, or monetization present. | ## Evidence status and limitations Evidence completeness: UNKNOWN - The real-world operator identity was not independently verified. - Module-level completeness metadata is unavailable for this legacy report. ## At a glance The checks that decide most of this verdict. | Check | Result | Status | | --- | --- | --- | | Malware engines | 16 flagged it (VirusTotal) | Risk | | Google Safe Browsing | Not listed (Google) | Clear | | Abuse reports on the host | 0 reports (AbuseIPDB; shared hosting inflates this count) | Noted | | Domain age | 2.5 years old (Registered history) | Clear | | Web archive | Archived since 2024 (Public history exists) | Clear | | Certificate | Encrypted connection (Issued by YR1) | Noted | ## The page as captured ![Screenshot of the rbfsci.com.br homepage captured during the TrustSniffer assessment](https://trustsniffer.com/outputs/rbfsci.com.br/screenshots/first.png) _What rbfsci.com.br served when TrustSniffer captured it on 2026-08-20. The page may look different now._ ## Key findings - Automated classification: Sensitive Interaction Risk. - Domain age: 1 to 3 years (registration continuity). - Public web-archive history exists since 2024. - At least one reputation service TrustSniffer consulted had flagged this domain at assessment time. ## Full analysis ### Security Alert Fortinet, Sophos flagged this site in external intelligence checks, indicating elevated compromise/scam exposure that requires immediate caution. The website at rbfsci.com.br currently presents only a “429 Too Many Requests” rate-limiting error page, with no visible interactive elements, business description, financial solicitation, or identifiable service proposition; its apparent purpose therefore cannot be established from the available presentation. ### Scam/Impersonation Risk **A confirmed blacklist signal creates a material security concern**, despite the captured page itself showing no login form, payment mechanism, wallet interaction, phishing form, or overtly malicious page behavior. Multiple external security detections, including detections attributed to Fortinet and Sophos, conflict with the otherwise limited and technically benign error-page behavior. No direct brand-impersonation or phishing mechanism was observed in the captured content, but the external detections and blacklist status are sufficient to make sensitive interaction inappropriate. The domain is also relatively recently registered, and the operator’s real-world identity remains unverified; these points do not independently establish fraud but reduce the basis for confidence. Evidence: - External reputation records: 16 malicious detections, with Fortinet and Sophos identified among the flagged vendors; blacklist status is true. - Domain registration record: registered 2024-03-01; age 2.47 years. - Archive records: 3 snapshots spanning 2024–2025, with 2 years tracked. - Homepage capture: HTTP 429 “Too Many Requests” response, with no forms, login elements, wallet connections, or external posts observed. ### Regulatory Verification Notes The accessible homepage is an error response and provides no legal, licensing, regulatory, or business-model disclosure. Consequently, no authorization or regulated status can be established from the site content. A registration record associates the domain with RBF Sistemas de Segurança Contra Incêndio LTDA, but the available identity-verification evidence does not independently connect that entity to the website’s operation. This is an identity and regulatory verification gap rather than an additional finding of impersonation. No matching broker-reputation record was returned in the supplied third-party context. Evidence: - Homepage: no company, licensing authority, registration number, terms, or regulated-service disclosure visible because the page resolves to a rate-limit error. - Registration record: owner listed as “RBF Sistemas de Seguran�a Contra Inc�ndio LTDA.” - Hosting record: served from AS26337, OIS1 - Oso Grande IP Services, LLC, US. - Transport security: TLS certificate issued by YR1 at DV validation level, valid to 2026-10-07T18:41:56+00:00. ### What to Verify Next Before any sensitive interaction, an independent check should confirm whether the named registered entity operates the domain and whether any activity later presented by the site requires authorization. Any claimed license should be checked directly with the relevant official regulator rather than through links or contact details supplied by the site. Official contact channels and ownership should also be validated through an independently sourced, offline route, and the site should be reassessed only after its substantive pages load consistently enough to review its terms and operating disclosures. Evidence: - The homepage currently provides no substantive service, legal, or contact content for independent review. - Operator identity is marked unverified by the available evidence. - The captured browser behavior shows a rate-limited response rather than a functioning service interface. ### Summary Verdict The overall posture is **critical and unsuitable for sensitive interaction**. Available evidence does not support confidence in the website’s operator identity or legitimacy, and the external security contradictions outweigh the absence of malicious mechanics in the limited page capture. ### Infrastructure Integrity The domain resolves directly to 108.167.168.15 on AS26337, operated by OIS1 - Oso Grande IP Services, LLC, in the United States. No CDN or WAF was detected, and the observed address is assessed as a likely origin host; the valid DV certificate provides transport encryption only and does not establish website legitimacy. Evidence: - Network resolution: 1 unique IP, 0 edge IPs, and 1 likely origin IP; direct address 108.167.168.15. - Hosting infrastructure: AS26337, OIS1 - Oso Grande IP Services, LLC, US; registry ARIN. - TLS certificate: issuer YR1, validation level DV, expiry 2026-10-07T18:41:56+00:00. ### Closing Assessment Sensitive actions should remain suspended unless independent legal-entity, authorization, and contact-channel checks produce a consistent basis for trust and the site’s substantive pages can be reviewed reliably. _Written analysis generated 2026-08-20 by the TrustSniffer Analysis Engine from the evidence in this report._ ## What the analysis found 2 findings contributed to this verdict, raised by registration and ownership, analysis engine, external reputation. ### 01 Governance Risk - The public registration record for this domain is incomplete. (Registration and ownership `rule:KF_WHOIS_INCOMPLETE`) ### 02 Sensitive Interaction Risk - The analysis matched a pattern TrustSniffer treats as a direct threat to a visitor. (Analysis engine `signal:direct_threat`) - An external threat feed lists this domain: either Google Safe Browsing marked it malicious, or a significant number of malware engines flagged it. (External reputation `rule:EXT_BLACKLIST_CRITICAL`) ## Identity verification | Field | Value | | --- | --- | | Status | UNVERIFIED | | Identity score | 30/100 | | Identity verification confidence | 50% | - No on-site identity signals detected _Identity verification measures whether the site can be independently connected to a real-world brand or person. It is separate from the classification confidence._ ## What TrustSniffer observed First-party facts recorded during the assessment of rbfsci.com.br. - The request stayed on rbfsci.com.br.

It is a starting point for your own judgement, not a guarantee: a high score means the signals were consistent with a legitimately operated site, a low or critical score means several risk patterns were present. TrustSniffer assesses a website from the evidence it can collect at a point in time: domain registration and age, hosting and certificate, the content the site served, and third-party reputation feeds. A score is a summary of that evidence, not a guarantee and not a legal finding. There is no human rating and no user review in it. A site can change after it is assessed. ## Related on TrustSniffer - [juazeiroresidencehotel.com.br risk report](https://trustsniffer.com/report/juazeiroresidencehotel.com.br) (Critical Risk, 0/100) - [apollodesigner.com.br risk report](https://trustsniffer.com/report/apollodesigner.com.br) (Critical Risk, 0/100) - [cortinadevidrobh.com.br risk report](https://trustsniffer.com/report/cortinadevidrobh.com.br) (Critical Risk, 0/100) - [2cs.com.br risk report](https://trustsniffer.com/report/2cs.com.br) (Critical Risk, 0/100) - [113acessorios.com.br risk report](https://trustsniffer.com/report/113acessorios.com.br) (Critical Risk, 0/100) - [10mais.com.br risk report](https://trustsniffer.com/report/10mais.com.br) (Critical Risk, 0/100) - [108bpo.com.br risk report](https://trustsniffer.com/report/108bpo.com.br) (Critical Risk, 5/100) - [estudiokohler.com.ar risk report](https://trustsniffer.com/report/estudiokohler.com.ar) (Critical Risk, 0/100) - [cespedelespartano.com.ar risk report](https://trustsniffer.com/report/cespedelespartano.com.ar) (Critical Risk, 0/100) - [vatstrading.com risk report](https://trustsniffer.com/report/vatstrading.com) (Critical Risk, 0/100) - [Every website and wallet TrustSniffer has assessed](https://trustsniffer.com/directory) - [Other domains assessed as high-risk or phishing](https://trustsniffer.com/directory/phishing-domains) - [Check another website](https://trustsniffer.com/web-intelligence) - [Check a crypto wallet address](https://trustsniffer.com/on-chain-risk) - [The TrustSniffer Risk Index](https://trustsniffer.com/stats) ## Guides - [Stablecoin Freezes, Sep 28, 2026: 24 Wallets](https://trustsniffer.com/blog/stablecoin-freeze-report-2026-09-28) - [Stablecoin Freezes, Sep 27, 2026: 3 Wallets](https://trustsniffer.com/blog/stablecoin-freeze-report-2026-09-27) - [How We See USDT Wallet Freezes Coming](https://trustsniffer.com/blog/how-trustsniffer-sees-usdt-wallet-freezes-coming) --- *Source: [TrustSniffer](https://trustsniffer.com/report/rbfsci.com.br) — independent automated trust & fraud analysis.
