What we watch for

Hostnames in phishing feeds and certificate logs are matched on these brand tokens; feed target labels are matched on the aliases. Generated spellings (typos, lure words, look-alike characters, other top-level domains) are derived from the official domains and tokens and checked against feeds, certificate logs and DNS.

Records and check details

Published records

DMARC (_dmarc.itau.com.br)
v=DMARC1; p=reject; sp=reject; fo=1; pct=100; rua=mailto:…@itau.com.br; ruf=mailto:…@itau.com.br; rf=afrf
SPF (itau.com.br)
v=spf1 ip4:200.196.144.0/20 include:parceiros.itau.com.br include:parceiros1.itau.com.br -all
DKIM
Unknown (no known selector). DKIM use requires a known selector or message to assess; a published key alone cannot confirm signing.

Interpretation

  • p=reject: receivers are asked to reject failing mail.
  • Relaxed DKIM alignment (default).
  • Relaxed SPF alignment (default).
  • pct=100 is a legacy tag removed by RFC 9989; its effect is receiver-dependent.
  • rf is a legacy tag removed by RFC 9989.
  • -all: unlisted hosts fail SPF.
  • 9 DNS-querying terms (include, a, mx, ptr, exists, redirect), counted recursively; the limit is 10.
  • Static check of the published record: syntax, every referenced include/redirect record, the DNS-lookup count and a/mx/exists targets (resolved to count void lookups). It does not evaluate SPF for any particular sending host.
