1. ISS World
Recovery And Mitigation Costs: $75 Million To $112.4 Million
A Feb. 17 ransomware attack forced Denmark-based facilities management firm ISS World to switch off its networks and leave hundreds of thousands of employees without access to their systems or email, according to Computer Weekly. Three days later, ISS World said the root cause of the attack had been identified and the company was working with outside experts to gradually restore our IT systems.
By March 20, ISS World said it had regained control of most of its IT infrastructure and was systematically relaunching business-critical systems, albeit with somewhat reduced functionalities. ISS said it expects to be finished with restoring and rebuilding its systems and IT assets by the end of 2020.
ISS expects to spend $45 million to $75 million on: remediating the IT incident; putting in workarounds to enable the continuous delivery of service; service underperformance because of system down-time; and cost duplication associated with contract operation. A rebuild of part of ISS’s IT infrastructure due to damage to some of the company’s IT assets is expected to cost between $22.5 million and $45 million.
