required) Two flavors for mail observables backed by the free, keyless XposedOrNot API: XposedOrNot_CheckEmail (fast breach-name list) and XposedOrNot_BreachAnalytics (per-breach dates, records, exposed data classes, password-storage risk, overall risk score, breached-site domains extracted as artifacts). Taxonomies: XON:Breaches (safe/suspicious), XON:Risk, and a malicious-level XON:PlaintextPwd when any breach stored plaintext passwords. Both flavors are TLP- and PAP-gated; an optional API key raises rate limits via the Plus API. Clean results render a not-found panel rather than an error; 429 responses return an actionable message. Includes README, service logo and report templates for both flavors.

This PR adds an analyzer for XposedOrNot — an open, free data-breach search service. Given a
mailobservable, it reports which known data breaches the address appears in.No API key or registration required. Both flavors work out of the box via the free keyless API (rate limits: 2 req/s, 25/hour per IP; the analyzer returns an actionable error when reached). An optional
keyconfiguration item (from console.xposedornot.com) switches to the commercial Plus API with higher limits.Flavors
XON:Breaches=<count>(safeat 0,suspiciousat 1+).XON:Risk=<label>and amalicious-levelXON:PlaintextPwd=yeswhen any breach stored passwords in plaintext. Breached-site domains are extracted asdomainartifacts for pivoting.Privacy / data egress
Only the observable's email address is sent (TLS) to xposedornot.com. Since an email address is PII, both flavors ship TLP- and PAP-gated (
check_tlp/check_pap, max 2 by default), and this is documented in the analyzer README.Testing
