Boeing said on March 28, 2018, it was hit by a cyberattack that some have identified as the infamous WannaCry ransomware. An internal memo obtained by the media states that the attack was ‘metastasizing rapidly’, possibly spreading to airline software and production systems, including some of manufacturing equipment used in building its 787 Dreamliner and newest 777X jetliners. But the U.S. plane maker is downplaying the attack saying it was limited in scope and has been contained.
