Link: Spam website with evasion indicators
Detects messages containing links to spam websites that show signs of evasion techniques, including blocklisted IP provider messages or rate limiting responses when analyzed.
Detection Logic
type.inbound
// single meaningful root domain in links
and length(filter(distinct(body.links, .href_url.domain.root_domain),
// filter out unrelated domains
.href_url.domain.root_domain != sender.email.domain.root_domain
and any(recipients.to,
.email.domain.root_domain != ..href_url.domain.root_domain
)
and .href_url.domain.root_domain not in ("aka.ms")
)
) == 1
// specific spam website pattern
and any(body.links,
// did not redirect to any other domain
ml.link_analysis(.).effective_url.domain.domain == .href_url.domain.domain
and (
// LinkAnalysis was "evaded"
any(ml.link_analysis(.).effective_url.query_params_decoded["q"],
strings.icontains(., "IP provider is blacklisted!")
)
// or we encountered the rate limiting
or ml.link_analysis(.).final_dom.inner_text == "Too Many Requests!"
)
