Is senff.app legit or a scam?
Phishing clone of Senff payment processor; 5-day-old domain harvesting CPF credentials, confirmed in phishing reports.
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.
Analysis Summary
Brand impersonation — not the real site

MT Intelligence
senff.app is a newly registered domain (5 days old) that replicates the invoice-access page of Senffnet Instituição de Pagamento Ltda, a legitimate 26-year-old Brazilian payment institution. The page presents a minimal form requesting only a CPF number under the guise of 'Fatura Digital' (digital invoice), claiming secure encrypted access but offering no business registration, privacy policy, terms of service, or contact details. Our research found two confirmed phishing reports submitted to PhishTank on June 17, 2026, for both senff.app and fatura.senff.app. The legitimate Senff company explicitly directs users to access invoices only through their official banking portal login or the Senff Clientes mobile app (rated 4.2 stars on app stores); there is no official senff.app invoice service. The hosting IP carries 65 abuse reports, and the domain is flagged as a clone of the legitimate senff.com.br. This combination of credential-harvesting form, impersonation of a real financial institution, phishing-database confirmation, and zero legitimate business presence makes this a high-confidence phishing attack.

Our research confirmed two phishing reports submitted to PhishTank on June 17, 2026, for both senff.app and fatura.senff.app. The legitimate Senffnet Instituição de Pagamento Ltda is a real Brazilian payment institution (CNPJ 03.877.288/0001-75) founded in 2000 and operating Banco Senff with a 7.9/10 rating on Reclame Aqui. However, Senff's official channels (senff.com.br, the Senff Clientes mobile app, and customer support) explicitly direct users to access invoices only through their banking portal login or the official app; there is no mention of a senff.app invoice service. Senff also publicly warns customers about fake boleto and phishing scams. The senff.app domain is a credential-harvesting clone with no legitimate business affiliation.
