The CNV is requesting an investigation into the origin of the attack and who was responsible. The hackers threatened to release 1.5 terabytes of financial information to the public within a week, and demanded a ransom of US$500,000. The financial information the attackers threatened to leak is in fact public, and includes balance sheets and other documents companies upload on its communication system, the CNV told the Herald on Monday. The Medusa ransomware operation first emerged in June 2021 and quickly expanded to target corporate victims, often demanding ransoms of a million dollars. The hackers have created a blog where they publish the data of victims who refuse to pay the ransom.
