Researchers are reporting that cyber attackers have stolen sensitive files belonging to Energias de Portugal (EDP) using the Ragnar Locker ransomware.
In a new web post, hackers claim that they have downloaded more than 10TB of private information. They threaten to release this information if EDP doesn’t pay a ransom of €10 million.
Screenshots of the data stolen, that are included in the post, indicate that the attackers already have access to a large amount of data. In a ransom note, the attackers claim to have access to confidential information on billing, contracts, transactions and more.
In a statement published by Current+, EDP confirmed that it was hit by a cyber attack on April 16th and continues to develop its response.
Ragnar Locker is a ransomware that can attack Windows-based systems. Attackers first began using the ransomware in a series of attacks against compromised networks in December of last year.
