elTOQUE (Mas Voces Foundation, Inc.)
July 2, 2026
•[ ddos, government, technology ]
From July 2 through July 8, 2026, elTOQUE received approximately 1.09 billion malicious automated requests intended to overwhelm eltoque.com and prevent access to its reporting. The campaign focused principally on the homepage, which hosts the outlet's widely used informal Cuban exchange-rate tracker. Protective systems stopped approximately 96% of the traffic before it reached the origin server, and the website remained online, although emergency mitigation rules temporarily delayed or impeded access for some legitimate users, particularly in Cuba. About 2,400 accompanying attempts to exploit website vulnerabilities were unsuccessful. Traffic came through rented data-center and cloud infrastructure in several countries and does not establish attribution. Given the sustained Cuban government pressure against elTOQUE, the politically sensitive target, and the pattern of earlier attacks, the actor country is coded Cuba as a low-confidence contextual assessment; the perpetrator and actor type remain undetermined.
