Well, this just happened… Airbus has been hit by a series of cyberattacks suspected to be from China.
This is the fourth attack on the company this year. In previous attacks, documents have been stolen relating to aircraft. In the previous attacks, hackers have targeted documents belonging to the A400, and other military aircraft that Airbus makes. It is unknown if the hacker(s) are state-backed, or independent. The attack has been suspected to be an attempt to steal aircraft plans. More info coming soon.
Edit 1: In further investigation, a series of documents relating to or directly to the A400 have been stolen. It is unknown if anything else has been taken.
