ISS Now Recovered from 2020 Malware Incident

ISS Now Recovered from 2020 Malware Incident
25 February 2021

The effects of the ISS IT security incident have been resolved with all related costs fully recognised and with the majority paid in 2020, according to the company’s annual report.

The facilities management company suffered interruption to business-critical systems in its  IT infrastructure in February 2020, including payroll and invoicing after being targeted with malicious software


All Systems Recovered


The attack affected many of ISS core IT systems and as a precaution, all ISS systems were turned off. On 20 March 2020, control of critical business applications was regained and a major exercise started to clean up and harden the IT infrastructure leading to full recovery of all systems. A programme launched in September 2020 to strengthen IT security and build a robust, centrally managed IT infrastructure to further mitigate risk of future attacks. 

The rebuild of the IT infrastructure non-cash write-down was predicted to be up to DKK 350 million and was finalised as DKK 365 million (around £42 million)

ISS states that: “We never made any attempt to contact the attackers; we do not know who they were, and we did not pay any ransom money.”

ISS also shared their 2020 financial results, reporting free cash flow of DKK 1.8 billion for 2020 against the latest financial outlook of “around DKK 2 billion”.

Jacob Aarup-Andersen, Group CEO, commented:

“2020 was a year that will not be forgotten. The global pandemic challenged ISS, economies and businesses around the globe. Our financial performance was negatively impacted by global lockdowns and throughout these challenging times, we have focused on the safety and health of our colleagues as they made a real difference for our customers and their employees.”
