Full timeline through 2026
2026 — Alinto SMTP relay metadata exposure in French email-provider leak
Cataloged incident. April 2026 specialist reporting traced a 40-million-record Elasticsearch leak at French email vendor Alinto to open SMTP logging metadata that indexed high-volume business correspondents—including L'Oréal, Renault, French government ministries, and diplomatic mailflows—without researchers finding full message bodies in the exposure. Security journalists emphasized spear-phishing and infrastructure-mapping risk flowing from relay topology rather than classic HR table dumps at L'Oréal itself. Consolidated SMTP-index Exposed categories include SMTP transaction metadata (sender, recipient, timestamps, relay IPs)—not message content per Krebs-on-security-adjacent trade summaries echoed by TechRadar and Cybernews. BreachHistory cites approximately 40M+ affected records in this row. See the loreal-alinto-smtp-metadata 2026 record and canonical BreachHistory entry.

- 2026 monitoring — New disclosures roll into this timeline as they are verified or labeled unverified per catalog policy.
