Colombia’s state-controlled energy company Ecopetrol said a cyberattack led to the theft of data linked to about 3,300 user accounts and that it could not guarantee the incident would not have a material adverse financial effect, according to Reuters.

The company reported it had not identified any critical disruption to operations, production capacity, or direct financial impact as of Friday, and it said the hacker had not yet disclosed stolen data.

Ecopetrol said the breach affected cloud-based file storage environments across 15 subsidiaries, and it added that it was able to prevent an attempted ransomware attack.

The firm said the attacker communicated extortion demands and threatened public disclosure of the information, and it is continuing to assess what data was exposed, which could include confidential, proprietary, or personal information, it warned.
