A ransomware attack last fall cost Universal Health Services $67 million in pre-tax losses, the healthcare provider confirmed in an earnings report released today.

Referring to it as an “information technology security incident,” UHS officials said the cyberattack forced the organization to suspend user access to several information technology applications in the US during the attack. No evidence of unauthorized access, copying or misuse of any patient or employee data was identified to date, according to UHS, one of the largest hospital and healthcare services providers in the US.
