Final answer:
The malware that disabled Maersk's computing systems was called NotPetya. It was a destructive cyberattack in June 2017 that led to significant operational disruptions and required extensive recovery efforts by the company.
Step-by-step explanation:
The malware that disabled Maersk's computing systems was known as NotPetya. This was a global cyberattack that occurred in June 2017, causing significant disruptions to businesses, governments, and infrastructure across the world. Maersk, being one of the world's largest shipping conglomerates, was severely affected with its operations halted as the malware spread through its network, encrypting files and demanding a ransom to unlock them.
NotPetya was particularly destructive because it was designed to spread quickly within organizations and did not include a reliable way for the attackers to decrypt files, even if a ransom was paid. As a result, Maersk had to undertake a massive recovery effort, reinstalling thousands of servers and computers over the course of several days to restore their systems to normal functionality.
