AI Generated Summary of the Ransomware Leak Page

On September 14, 2026, the ransomware group known as thegentlemen listed Humboldt, an educational institution in Brazil, on its leak site. The post identifies Humboldt as a bilingual school in São Paulo serving approximately 1,200–1,300 students, ranging from early childhood through secondary education, with roughly 295 staff members. It describes the institution as having German cultural and educational ties, a large campus, bilingual and international study tracks, language certifications, and vocational programs in areas including administration, logistics, and information technology. The threat actors claim to possess approximately 300 GB of Humboldt data. The listing therefore indicates an alleged data-leak or data-theft impact, but it does not state that the institution’s systems were encrypted. No compromise date separate from the publication date is provided, so September 14, 2026, is treated as the post date. The post does not provide a ransom demand or claimed payment amount. No screenshots or other images are included, and the listing does not provide additional publicly described evidence or download material.
