Questions about rfb.gov.br

Is rfb.gov.br safe?
The scan of rfb.gov.br on 19 Aug 2026 reached no verdict either way (score 6). Too little was captured to judge it, which is an unknown rather than a pass.
What malware is associated with rfb.gov.br?
1 analysed samples communicate with this URL, including Genpack.
How was rfb.gov.br checked?
A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the fast tier allows, a headless browser rendered the page and recorded every request. Egress is SSRF-locked. Signatures that matched only page text are weighted far below one that matched a served file, because a page documenting malware matches the same rules.
