World’s Second-Largest Container Line Maersk Confirms Cybersecurity Incident Involving Data Theft

Shipping company Maersk has confirmed that an attacker gained unauthorised access to one of its local legacy systems and extracted data.

In a statement published on November 11, 2026, Maersk said that it identified an IT security incident. WhiteArmor, a ransomware group, claimed responsibility for the attack and threatened to release about 100 GB of data from Maersk’s OCF/LF Logistics platform.

WhiteArmor listed Maersk on its data leak site over the weekend and publicly demanded $5 million as ransom. According to reports, the group has given Maersk 30 days and asked for the payment in Bitcoin.
