⚠️ 🇪🇸 🇨🇴 🇪🇨 🇲🇽 🇨🇱 🇵🇪 🇦🇷 🇨🇷 🇵🇦 🇬🇹 🇭🇳 🇸🇻 🇮 🌐 PREVENTIVE ALERT – ALLEGED EXFILTRATION OF FIBER INFRASTRUCTURE AND DATA FROM UFINET LATAM (ACTOR: 3TERNAL)
[STATUS: ALLEGED / UNCONFIRMED / THREAT ACTOR: 3TERNAL (GRIMGROUP) / DATE: NOVEMBER 3, 2026]
Centralized cyber-intelligence systems have intercepted a post on underground forums (dated November 3, 2026) by the threat actor "3ternal," acting on behalf of the group "GrimGroup." The report claims the compromise and subsequent exposure of internal infrastructure belonging to Ufinet Latam, a wholesale fiber-optic operator with a presence in Spain and Latin America.
The attacker details the extraction of data from an internal platform (KeyCom / Keypro Cloud), which includes information on physical telecommunications infrastructure—georeferenced using WGS84 coordinates—as well as records of utility poles, cables, network devices, and corporate email accounts belonging to staff, partner operators, and suppliers.
It is strictly noted that the veracity of this intrusion, the initial compromise vector, and the overall authenticity of the exposed data have not been officially confirmed by the company or incident response centers.
Threat Actor: 3ternal (GrimGroup).
Victim : Ufinet Latam (Wholesale fiber-optic operator in Spain and Latin America).
Sector: 📡 Telecommunications, Critical Infrastructure, Fiber-Optic Networks, and Connectivity. Publication Date: November 3, 2026.
Reported Scope: 44 operators, 402,756 utility poles, 296,687 cables, and 1,759 corporate email accounts.
Nature of the Incident: Alleged compromise of a network management platform, involving the exfiltration of fiber-optic network mapping—including precise geographic coordinates—and infrastructure inventory.
🛡️ TECHNICAL PREVENTIVE AND CONTAINMENT RECOMMENDATIONS (FOR SOC / CSIRT / OPERATORS)
Security Audit of Cloud and GIS Platforms: Technical teams at Ufinet and partner operators must immediately verify access to their geographic management platforms (KeyCom / Keypro Cloud) and revoke any compromised credentials.
Protection of Critical Infrastructure: Given the leak of coordinates for fiber nodes, splice points, and utility poles, it is recommended to strengthen both physical and logical surveillance of critical network points to prevent sabotage or physical intrusion.
Email Account Monitoring: Invalidate and monitor the 1,759 exposed corporate mailboxes to mitigate the risk of targeted phishing attacks and social engineering attempts against technical and administrative staff.
