Cosan S.A.

Cosan S.A., also known as Cosan Group, is a Brazilian conglomerate that operates primarily in the energy and agribusiness sectors. Its core activities involve the cultivation, processing, and marketing of sugar and ethanol, as well as the production and distribution of bioenergy products. The company also participates in fuel distribution through its downstream operations and markets lubricants under its own brand. Additionally, Cosan has a logistics division that provides rail transportation services for various commodities. These operations serve domestic markets in Brazil and extend to international customers through export channels.

Cosan’s headquarters are located in Brazil, as indicated in the organisational context. The company is listed on both the São Paulo Stock Exchange (B3) under the ticker CSAN3 and the New York Stock Exchange (NYSE) under the ticker CSAN, reflecting its status as a publicly traded entity. Through joint ventures and wholly owned subsidiaries, Cosan holds stakes in ventures such as Raízen, a major sugar, ethanol, and bioenergy enterprise formed with Shell, and Rumo Logistics, which focuses on rail freight. These structural arrangements illustrate the group’s approach to combining agricultural production with energy processing and logistics infrastructure.

The organisation’s distinguishing attributes include its integration of sugarcane cultivation with ethanol production and bioenergy generation, which positions it within Brazil’s renewable energy landscape. Its involvement in both upstream agricultural activities and downstream fuel distribution allows it to manage a significant portion of the value chain for biobased products. The ransomware incident reported on 31 March 2020, in which Netfilm operators compromised Cosan’s systems and exposed approximately 3.1 GB of sensitive data, highlights a cybersecurity challenge faced by the conglomerate. This event was identified by the Cyble Research Unit and underscores the exposure of large enterprises to ransomware threats despite their established market positions.
