Downloads and caches the Disconnect.me services.json feed (24h TTL),
matching domains against the Advertising, Analytics, Social, Content,
and Disconnect categories. Severity is warn (privacy classification,
not malware). Reuses the shared feedCache infrastructure.
Downloads the Botvrij.eu public IOC domain list (no API key required),
caches it in-process with a 6h TTL, and flags any registered domain
that appears directly or as a parent of a feed entry.
Add two shared helpers to source.go and apply them across all sources:
- disabledResult(id, name) replaces the repeated inline SourceResult literal
- evidenceEval(r, severity) replaces the identical Evaluate body in 6 sources
ThreatFox queries the IOC database for domain indicators (C2 servers,
malware distribution, phishing); MalwareBazaar searches for malware
samples tagged with the domain. Both require a free abuse.ch Auth-Key.
Each source's Query() method previously set r.Listed and r.Severity,
embedding verdict logic inside the prober. Evaluation now lives in a
dedicated Evaluate(SourceResult) (bool, string) method per source,
keeping Query() as pure observation.
A package-level EvaluateResult() helper looks up the source by ID and
delegates to its Evaluate method; rules.go, report.go, types.go, and
provider.go all call this instead of reading pre-set r.Listed/r.Severity
values. An unknownSource sentinel handles results whose source is no
longer registered.
