humboldt.com.br zoominfo.com/c/humboldt/372537346 Colegio Humboldt 300gb DATA Germany's official school in São Paulo — founded in 1916 by German immigrants (first class: 41 students, May 1, 1916), now a non-profit bilingual school of ~1,200–1,300 students (ages 2–18, ~295 staff) on a 60,000 m2 Interlagos campus built with German government funding (opened 1999), maintained by the parents' association SEBRB. Its dramatic history: closed twice by world wars — 1917 (WWI) and 1942 (WWII, when all assets were confiscated and took a 10-year legal battle to recover) — before parents rebuilt it into a top institution. Programs: two tracks (Bilingual — 40% German; International German — 80% German leading to the Abitur, with 100% pass rate and direct entry to German/European universities), plus DSD I/II, Cambridge, DELE certifications, and its crown jewel — the largest German dual vocational training center outside Germany (since 1982: 2-year technical programs in Administration, Logistics, IT.

Not assessable
Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
