# TheGentlemen ransomware claims Brazilian university Published: 2026-10-16 · Severity: high · Sectors: education Canonical: https://vorant.io/reports/9dbda8d9-9941-5cf6-935b-f45dbe83306a/thegentlemen-ransomware-claims-brazilian-university > Ransomware group TheGentlemen listed Universidade de Passo Fundo, a Brazilian university, as a victim on its leak site. Ransomware.live, a tracker that indexes ransomware group leak-site postings, recorded Universidade de Passo Fundo (UPF) — a private philanthropic university in Rio Grande do Sul, Brazil, with roughly 10,000 students and 7 campuses — as a listed victim of the ransomware operation known as "TheGentlemen." The entry consists primarily of background information about the university (accreditation, academic programs, financial standing, leadership) rather than details of the intrusion itself, and includes DNS records found for the victim's domain. No technical details about the initial access vector, exploited vulnerabilities, malware deployed, ransom demand, or exfiltrated data volume are provided in this listing. The source explicitly states it does not access, host, or redistribute any stolen data, and only indexes publicly visible claims made by ransomware operators. As such this should be treated as an unconfirmed leak-site claim pending further corroboration. Defenders in the education sector, particularly higher-education institutions in Brazil and Latin America, should be aware that TheGentlemen is an active ransomware/extortion group currently naming victims on a leak site. Organizations should monitor for any further disclosure from this actor, review their own exposure to common ransomware initial-access vectors (exposed RDP/VPN, phishing, unpatched edge devices), and ensure backup and incident-response plans are current given the ongoing activity of this group. ## Mentioned in this report - Threat actors: The Gentlemen 1 detection for this report is in the app: the rules that match its indicators, the Sigma rules already converted to Splunk SPL, to Elastic where their fields map onto Elastic's integrations and to Microsoft Defender XDR KQL wherever Defender records the activity, and the YARA and Suricata.
