Tejucana

Tejucana is a mining company headquartered in Brazil. The firm is engaged in the extraction of mineral resources, although the specific commodities it produces are not detailed in the available sources. Its activities are situated within the broader mining sector.

No explicit information regarding the company's size, workforce, revenue, or geographic reach is provided in the sources. Consequently, any description of its scale or market footprint would be speculative and is omitted here.

In August 2022, Tejucana was identified as one of the mining firms whose internal emails and documents were exfiltrated by the hacktivist collective Guacamaya. The collective released over two terabytes of data through Enlace Hacktivista and the transparency platform DDoSecrets, framing the leak as a denunciation of environmental exploitation and pollution by international corporations operating in Central and South America. Tejucana’s inclusion meant that its internal communications were among those cited in the broader critique of corporate practices. The incident followed an earlier Guacamaya operation that had released approximately 4.2 terabytes of data from other mining subsidiaries. Collectively, these leaks contributed to a global investigative journalism collaboration examining the impacts of resource extraction.
