Maersk says an isolated legacy-system incident shows no sensitive-data disclosure, operational impact, or ransom demand so far.

A.P. Moller-Maersk said on November 11 it is investigating an IT security incident involving a local legacy system inherited in a prior acquisition. The Register describes potential data theft; GBHackers reports unauthorized access and data extraction. Maersk says the affected system was secured, the incident appears isolated, and other systems—including customer and partner API and EDI connections—were not affected. Findings so far strongly suggest no sensitive data was disclosed. The company does not expect operational disruption, says booking and shipment platforms remain usable, and, according to GBHackers, has not reported encryption or a ransom demand.
