In 2017, a cyber attack against Maersk Line, a large container transport company, resulted in thousands of their devices disrupted by the NotPetya ransomware by having the contents on those devices encrypted and made inaccessible to the company. The firm eventually rebuilt over 45,000 desktops and over 2,500 servers. Port operations in 76 countries were impacted, costing the company $300M in lost revenue and remediation costs. Hundreds of companies had their logistics chains stopped or severely degraded. Researchers have tied the distribution of the ransomware to efforts by a Russian APT. According to the classification system presented, the primary effect to Maersk’s devices is best described as a: 1 point Data Attack Sensor Exploitation External Denial of Service Attack Internal Denial of Service Attack Message Manipulation Attack
