On the morning of March 28, the Seattle Times reported the WannaCry ransomware had infiltrated aerospace manufacturer Boeing. The paper cited an internal memo from Mike VanderWel, chief engineer at Boeing. It’s hard to imagine a memo more alarming: “It is metastasizing rapidly out of North Charleston and I just heard 777 (automated spar assembly tools) may have gone down,” VanderWel wrote.

But in a statement later that day on Twitter, Boeing pushed back on reports the attack had been extensive. “A number of articles on a malware disruption are overstated and inaccurate,” the statement said. “Our cybersecurity operations center detected a limited intrusion of malware that affected a small number of systems. Remediations were applied and this is not a production or delivery issue.”
