Colombian Energy Firm EPM Suffers Ransomware Attack – UMBRA Defeats Ransomware and Maintains Operations

A ransomware attack hits Colombian Energy company EPM on Monday, disrupting its operations and taking down online services.

Empresas Publicas de Medellin (EPM) is one of Colombia’s largest public energy, water and gas providers, supplying services to 123 municipalities.

On Tuesday, the company informed around 4,000 of its workers to work from home, with IT infrastructure down and the company’s websites no longer available.

The company reported that they were responding to a cybersecurity incident and provided alternative methods for customers to pay for services. This was done to prevent further disruption to the company’s operations.

The BlackCat ransomware operation, aka ALPHV, was responsible for the attacks. They claimed to have acquired business data while carrying out the operations.
