Maersk Cyberattack 2017

December 17, 2017 Security

The cyberattack on Maersk, one of the world's largest shipping companies, involving the NotPetya malware in June 2017, stands as a landmark in the history of cyber incidents due to its scale, complexity, and the significant financial cost incurred by the company. NotPetya was initially disguised as a form of ransomware, but it became evident that its primary purpose was to disrupt and destroy data, not to collect ransom.

Attack Overview

NotPetya exploited vulnerabilities in Microsoft Windows operating systems, including ones that had been addressed by patches that were not universally applied across organizations. It spread rapidly across networks, rendering computers inoperable and encrypting files. NotPetya was particularly insidious because it used legitimate system tools to propagate itself within networks, making it harder to detect and stop.

Impact on Maersk

Maersk was hit hard by NotPetya, with the malware penetrating its systems globally and affecting its operations across 600 port terminals and offices in 130 countries. The company's IT systems were crippled, leading to significant disruptions in its ability to manage and operate its shipping and logistics services. To resolve the issues, Maersk had to reinstall over 4,000 servers, 45,000 PCs, and 2,500 applications over the following weeks—a Herculean task that required a coordinated effort from its global IT team and external cybersecurity experts.

Cost to Maersk

The financial impact on Maersk was staggering. The company publicly disclosed that the cyberattack cost it between $250 million to $300 million, a figure that underscores the severe implications of such incidents on corporate finances. This estimate included not only the direct costs of responding to the attack, such as IT recovery efforts, but also the indirect costs from business interruption, including lost revenues and operational delays. The incident highlighted the vulnerability of global supply chains to cyber threats and the importance of cybersecurity measures in protecting critical infrastructure.

Lessons Learned

The NotPetya attack on Maersk served as a wake-up call for businesses worldwide about the risks of cyber warfare and the importance of cybersecurity. It demonstrated that companies could become collateral damage in cyber conflicts between nations, as NotPetya was widely attributed to state-sponsored hackers. Following the attack, there was a marked increase in awareness and investment in cybersecurity measures within the shipping industry and among other sectors vulnerable to similar threats. Companies began to place greater emphasis on implementing robust security protocols, conducting regular vulnerability assessments, and ensuring that all systems are promptly updated to defend against potential cyberattacks.

The Maersk incident illustrates the profound impact that cyberattacks can have on global businesses and the economy at large, reinforcing the need for comprehensive cybersecurity strategies and international cooperation to combat cyber threats.
