Hackers stole data on Airbus employees in a cyber attack on systems of the French aircraft maker, according to a company press release.

Airbus
said it detected a cyber incident on its “Commercial Aircraft business”
information systems, “which resulted in unauthorised access to data.” The
company’s commercial operations were not affected.

“This
incident is being thoroughly investigated by Airbus’ experts who have taken
immediate and appropriate actions to reinforce existing security measures and
to mitigate its potential impact, as well as determining its origins,” reads
the notice.

Airbus
is now trying to figure out whether specific data was targeted, which would
help build a profile of the attacker (i.e. a competitor or a state-sponsored
hacker looking to steal engineering blueprints).

“However
we do know some personal data was accessed. This is mostly professional contact
and IT identification details of some Airbus employees in Europe,” Airbus
confirmed.

Airbus,
which designs and manufactures aircraft ranging from commercial airliners to
combat planes and helicopters, employs a massive workforce of around 129,000.

As
per the EU’s General Data Protection Regulation requirements, the company has
immediately contacted the relevant regulatory authorities to provide a formal
notice of the breach.

“Airbus
employees are being advised to take all necessary precautions,” Airbus
concluded.

Last
year, the WannaCry ransomware infected “a small number of systems” at Boeing,
the world’s largest manufacturer of commercial airplanes.
