The company added: "Meanwhile, Cosco Shipping Lines has already checked the operating system, and updated the patch and the virus database." But despite the damages caused by NotPetya, cyber-attacks have continued to disrupt the shipping industry, as per recent data breaches suffered by UK shipbroker Clarksons and an Australian division of Maersk, respectively. And as the industry continues to ramp up its cyber defenses, tools that can track vulnerable ships have surfaced that companies hope could protect against the next NotPetya. Cosco has yet to confirm that this week's "network breakdown" was the result of ransomware, but according to Bleeping Computer, the company has reminded its staff not to open suspicious emails. The Daily Swig has reached out to Cosco for comment.
