WhiteArmor claimed the system held logistics and account data
WhiteArmor listed Maersk on its leak site on Nov 7 and threatened to publish information it claimed to have obtained unless Maersk paid a $5 million ransom, according to WhiteArmor.
The group claimed to have obtained approximately 100GB of data from a platform associated with LF Logistics, a Hong Kong-based logistics company acquired by Maersk in 2022. Its claims included roughly 29,000 driver records, 16,123 staff accounts and more than 27,000 mobile device logs.
The alleged data also included delivery recipients’ information, signed delivery receipts, inventory records, purchase orders and shipping notices. Maersk has not confirmed the types of data extracted.
Maersk said customer operations could continue
Maersk said it did not anticipate disruption to operations for customers at this time, and customers could continue to use its platforms to book and manage shipments as usual.
Infosecurity Magazine reported that Maersk had not clarified when the unauthorized access occurred.
Logistics companies have faced similar claims
Nick Harris said several WhiteArmor attacks targeted logistics companies, including J.B. Hunt, Ryder and Echo Global Logistics.
Treat possible insider recruitment as “assumed compromise” and set controls and alerts accordingly, Nick Harris said.

The company has not confirmed WhiteArmor’s involvement or identified the types of data extracted. It also advised people to treat unexpected communications claiming to relate to the matter with caution and verify them through their usual Maersk contact.
