As initially reported by The Air Current, Boeing suffered an outage that “significantly disrupted” its commercial and military production. News of the outage first broke after the publication reported it, following interviews with people reportedly familiar with the matter.

The outage occurred on the last day of the quarter, a day Boeing usually spends trying to hand over as many planes as possible to customers to boost its financial standing.

However, the outage meant that final inspections of commercial jets and related paperwork were stopped.

While the timing may raise a few eyebrows regarding whether cyber criminals were involved, Boeing has confirmed the outage but said there is nothing to indicate that a cyber attack was to blame.

“We experienced an unplanned IT outage that affected some computer systems and applications,” Boeing said in a statement.

“The cause of the outage is understood – we have no reason to believe it is due to a cyber attack – and our IT team is working to bring all systems back online.”

Cyber Daily has not observed any threat actors claiming responsibility for the incident nor noted any evidence of cyber crime.

Last year, a supplier for Boeing, Airbus, Nissan, Samsung, Volkswagen and more was hit by threat actors, with claims made of stolen data.

DCS Software Solutions, a company that offers software solutions such as IT support, website development, and cloud account management to businesses, was listed on the dark web leak site of the J Group ransomware gang on 1 October.

The threat actor claimed to have stolen 11 gigabytes of data from DCS, including sensitive legal documents like insurance policies and certificates, client-side metadata, including user permissions and audit trails, config files for CAE, HPC and PLM systems, documentation and architecture for proprietary software and the internal procedures for technical support, security and backups.

To back up its claims, J Group posted a compressed folder along with a .txt file listing allegedly stolen .pdf files, which the threat actor claims were signed with the names of current and former employees. Other documents included training documents and yearly expense reports.

The compressed folder contained a number of internal documents from Sandvik, DCS’s parent company, including requirements, insurance documents, and more.
