(Reuters) — A series of cyberattacks on Airbus in the past few months were conducted via the computer systems of its suppliers and contractors and security sources suspect a link to China, AFP news agency reported on Thursday. Airbus, the world's second-largest aerospace group, did not immediately respond to a request for comment on the report. China has repeatedly denied involvement in hacking and neither the foreign ministry nor China's official cyber regulator responded to requests for comment on the report. Airbus said last January that a cyberattack on its systems had resulted in a data breach. Last year, U.S. prosecutors said Chinese intelligence officers and hackers stole information about a jet engine being developed by firms who supply Airbus as well as its U.S. rival Boeing. According to the AFP report, which cited multiple unnamed security sources, cyberattacks in the past months on Airbus were mounted via French technology consultancy Expleo, engine maker Rolls Royce, and two French Airbus subcontractors which were not identified. Expleo and Rolls Royce did not immediately respond to requests for comment. Over the past 12 months, Airbus has been targeted by four major cyberattacks, AFP cited one of the sources as saying. Some of the attacks date back further, the report said. The report cited the sources as saying the hackers appeared to have been seeking information about engines for the A400M military transport aircraft and A350 airliner. The AFP report did not make clear whether the cyberattacks it described had led to data breaches or affected Airbus operations. It said the security sources have not definitively attributed responsibility for the cyberattacks, but that they bore the hallmarks of groups linked to Chinese intelligence.
Airbus's supply chain has been the target of four cyber attacks within the last year in a coordinated attack that may have originated from China, according to the news outlet AFP. The Chinese government is also suspected of being behind an attempt by hackers known as Fancy Bear and Cozy Bear, which are believed to be linked with Russian intelligence, to steal data on Airbus planes during their The incidents appeared to be focused on gleaning data about engines for the A400M military transport aircraft and A350 airliner. Furthermore, US prosecutors claimed that China was behind attacks last year on Airbus suppliers working on an engine, while Airbus confirmed a breach of its own systems in January 2019.
