Cooperativa de Electricidad Obras y Servicios Públicos de San Antonio de Areco

Cooperativa de Electricidad Obras y Servicios Públicos de San Antonio de Areco (CEOSP) is a utility cooperative based in San Antonio de Areco, Argentina. As indicated by its name, the organisation provides electricity works and public services to the local community. Being a cooperative, it is owned and governed by its members who are typically the consumers of its services. It serves the community of San Antonio de Areco.

In March 2023, CEOSP experienced a significant cyberattack that disrupted its operations and forced a temporary closure of some facilities. The incident was initiated by a malicious email that introduced a virus across the organisation's computer systems, rendering many machines inaccessible. Attackers reportedly demanded a ransom for the restoration of files containing years of operational data. Despite the disruption, the cooperative reported that its emergency electrical services continued to function during the event.

CEOSP publicly acknowledged the cyber incident but did not confirm whether a ransom was paid or if any data was compromised. The attack highlighted vulnerabilities in the cooperative's IT environment and prompted its technical teams to work continuously to restore normal operations. As a member‑owned entity, CEOSP's governance structure emphasizes local control and accountability to the community it serves. No further details about its size, subsidiaries, or parent organisations are available in the provided information.
