According to Ciso Advisor, the hackers commanded a ransomware attack on October 3 and 4, hijacking 25 servers with 874 GB in files.

Now, the hackers threaten to sell all content through an auction on the Dark Web if the ransom they requested is not paid. The group posted a message:

„We have 874 GB of data, corporate and private documents, as well as files affecting investors obtained from the company’s local network on more than 25 file servers; before downloading the information only the most important and critical are analyzed and downloaded.

In a few days we will publish some of the company’s files here.

We will auction all the data later“.

Although hackers say there was a ransom demand, the figures were not disclosed. Ransomware operators have been known to hack into the systems of companies and public entities, with several cases registered this year.

In September, Revil led a Chilean public bank to close its branches in a similar attack. Before that, in July, the group attacked Spain’s railroad company ADIF, also stealing over 800 GB of data.

The group also usually ransom Monero after hijacking the systems and files. Also in July, one of the victims was Argentina’s largest telecom company, demanding a ransom of US$7.5 million in its privacy-focused currency.

Brazil is one of the countries in the world that suffers most from cyber attacks. Half of the orchestrated attacks against companies in Latin America have targeted companies in the country.
