Maersk confirms a data breach involving a legacy system, with 100GB of data stolen and a $5 million ransom demanded.

## Steps
1. Search the repo, its CI and infra config for Maersk. If present, report the version in use and whether it's affected.
2. No source names a fix yet; check the vendor advisory. Until one ships: restrict network access to it.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.
