Oldelval, the operator of Argentina’s primary crude oil pipeline network, has confirmed that hackers successfully breached its administrative systems.
The company disclosed the incident to the securities regulator, clarifying that while unauthorized access was achieved, the physical transport of crude oil was never interrupted.
Operational continuity was maintained throughout the event, preventing any immediate supply shock to the market.
The cyberattack is attributed to the same threat actor responsible for a breach at Ecopetrol, Colombia’s state-owned oil company, just two weeks prior.
This pattern suggests a coordinated campaign targeting critical energy infrastructure across Latin America.
While the current incident did not disrupt flows, the recurrence of attacks on major regional operators raises concerns about the resilience of the sector’s digital defenses.
