Brazilian airplane manufacturer Embraer’s data has reportedly been uploaded on a dark web website hosted by ransomware group RansomExx (a/k/a Defray 777) after Embraer reportedly refused to pay a ransom following a ransomware attack last month.

According to ZDNet, the hackers uploaded company files containing “samples of employee details, business contracts, photos of flight simulations, and source code, among others.”

In leaking the data and making it publicly accessible, sometimes selling it at auction, is designed by the attackers to put pressure on the company to pay the ransom to avoid legal obligations and regulatory fines or penalties, or to avoid access to confidential data by competitors and adversaries that can be used against the company.
