What’s Behind the Wolters Kluwer Tax Outage?
Summary: KrebsOnSecurity reported on May 3, 2019 that CCH's software download directories were open and writable by any anonymous user, with suspicious PHP and text files present, and the directory was taken offline shortly after. Wolters Kluwer later confirmed a malware installation detected on Monday, May 6, took a broad range of platforms offline as a precaution, and had restored CCH Axcess, CCH SureTax, CCH AnswerConnect and CCH Intelliconnect by May 7 while stating it saw no evidence customer data was compromised.
Bottom line: Accountants reported being unable to file clients' May 15 returns or reach their clients' tax data in the cloud, and Wolters Kluwer's own support line played a message about technical difficulties while emails and calls went unreturned - the outage and the silence around it landed on firms with filing deadlines and no local backup.
