Legal and business publisher Wolters Kluwer says it has discovered malware in a number of its platforms and applications and has taken them offline in order to reduce the malware’s impact.

It has found no evidence that customer data was compromised or that the malware has spread through its systems to any customers, it says.

Following is the statement released by Wolters Kluwer:

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. 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. On May 7, we were able to restore service to a number of applications and platforms.

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.

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 apologize for any inconvenience this may have caused.
