Days after a Russian-affiliated ransomware group claimed responsibility for a cyber breach, Boeing confirmed a cyberattack was affecting Global Services operations—online, at least.

“We are aware of a cyberincident impacting elements of our parts and distribution business,” a Boeing spokesperson told Manufacturing Dive, which like Aviation Week Network is owned by Informa. “This issue does not affect flight safety.”

As of Nov. 4, the services.boeing.com website continued to state: “site down due to technical issues.”

News reports in late October said ransomware group Lockbit claimed to have sensitive data from the large defense prime and OEM, and it threatened to publish some unless Boeing started cooperating with the hackers by Nov. 2. Citing the U.S. Cybersecurity and Infrastructure Security Agency, Reuters said Lockbit has been responsible for 1,700 cyberattacks in the U.S. over three years.
