Wolters Kluwer global services hit by malware

Wolters Kluwer, the company behind cloud accounting software CCH, has been impacted by a malware infection, leading to service disruptions across the globe, including Australia.

“On Monday, May 6, we started seeing technical anomalies in a number of our platforms and applications. We immediately started investigating and discovered the installation of malware,” an official statement from Wolters Kluwer said.

“As a precaution, in parallel, we decided to take a broader range of platforms and applications offline. With this action, we aimed to quickly limit the impact this malware could have had, giving us the opportunity to investigate the issue with assistance from third-party forensics consultants and work on a solution.


“Unfortunately, this impacted our communication channels and limited our ability to share updates.”

The company had come under flak for not sharing more information around the outage, with several Australian users taking to social media to request for an estimated timeline for services to be restored.

Speaking to Accountants Daily, Wolters Kluwer APAC managing director Izzy Silva said that, as of 8 May, all applications and platforms have had their service restored.

Mr Silva said its customer-facing platforms — CCH iFirm, CCH Intelliconnect, CCH iKnow/IQ, CCH PinPoint, CCH Integrator, CCH Tax Integrator, and CCH Lodgment Portal — were not impacted by this interruption.

“We regret any inconvenience and that we were unable to share more information initially, as our focus was on investigation and restoring services as quickly as possible for our customers,” Wolters Kluwer said.

“We have seen no evidence that customer data was taken or that there was a breach of confidentiality of that data. Also, there is no reason to believe that our customers have been infected through our platforms and applications.

“Our investigation is ongoing. We want to apologise for any inconvenience this may have caused.”
