Analysis · EC · Energy & Transportation
What began as unauthorized access has now turned into a full-blown data leak, with stolen information from 15 subsidiaries published online. Ecopetrol is actively coordinating with Colombia's Attorney General and tech ministry to take down the illegally published material.
