Airbus-owned Stelia North America has been hacked in an apparent ransomware attack.

In a statement, Steila confirmed the attack, saying: “Upon detection, we immediately activated our cyber defence protocols and took proactive measures, including isolating affected systems, to mitigate the threat. We can confirm this incident is strictly contained to the Stelia North America IT environment and does not impact the broader Airbus Atlantic network. We are conducting a comprehensive forensic investigation alongside leading external cybersecurity experts. The safety and security of our people, our operations, our data, and our partners remain our absolute priority.

“We are maintaining close coordination with relevant authorities and keeping our employees and customers informed as the situation evolves.

“To protect the integrity of the ongoing investigation, we cannot provide further details at this time. So we will not further comment on the identity of the perpetrators, their methods, or the specifics of their claims.”

While Stelia has not commented on the identity of the perpetrators, cybersecurity film Comparitech has said that a group named Rhysida has claimed responsibility, demanding a 27 bitcoin ($2.07 million) ransom demand for 10 TB of data. A ransom deadline of seven days was set before the data will be released.

[Update: An earlier version of this story suggested that all divisions of Stelia, including Stelia Aerospace were involved in the data breach. In fact, just Stelia North America is affected.]
